Write the equation of the line in slope-intercept form and identify the slope.
−5x + 10y = 20
Answer:
Slope = 1/2Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question the equation is
- 5x + 10y = 20
To find the slope we must first write the equation in the form above
- 5x + 10y = 20
Move - 5x to the right side of the equation
10y = 5x + 20
Divide both sides by 10
We have
[tex]y = \frac{5}{10} x + \frac{20}{10} [/tex]
[tex]y = \frac{1}{2} x + 10[/tex]
Comparing with the general form of equation above
Slope / m = 1/2

x/8 - 5/2 =5/2
Answer:
x = 40
Step-by-step explanation:
x/8 - 5/2 =5/2
x/8 = 10/2
x/8 = 5
x = 40
Answer:
[tex]\Huge \boxed{x = 40}[/tex]
Step-by-step explanation:
x/8 - 5/2 = 5/2
Add 5/2 to both sides of the equation.
x/8 - 5/2 + 5/2 = 5/2 + 5/2
Simplify the equation.
x/8 = 10/2
x/8 = 5
Multiply both sides of the equation by 8.
(8)x/8 = (8)5
x = 40
Here is a rule to make a sequence. The next term is 4 less than 3 times the previous term. .Starting with the initial term of 10, build a sequence of 5 numbers.
Answer:
So the sequence of the five numbers are;
10,26,74,218,650
Step-by-step explanation:
In this question, we are interested in building a sequence of 5 numbers given the initial term.
Okay, to build this sequence, we will need to look at the rule that guides the building of the new sequence:
The rule is that the next term is 4 less than 3 times the previous term.
Okay, let’s call the next term y, while the previous term is x.
Following what was specified in the question;
y = 3x -4
Recall; the next term(y) is 4 less (-4) than 3 times (3 multiplied by) the previous term (x)
So let’s start with the initial term of 10.
The next term will be;
y = 3(10) -4 = 30-4 = 26
The next term after 26 will be ;
y = 3(26) -4 = 78-4 = 74
The next term after 74 will be;
y = 3(74) -4 = 222-4 = 218
The next term after 218 will be;
y = 3(218) -4 = 650
The function h(x)= 12x^8+49 is an even function. Which transformation of h(x) would result in a function that is neither even nor odd?
Answer:
A translation (9 units) to the left will result in a function that is neither even nor odd
Step-by-step explanation:
With horizontal translation to the left, we have;
h(x) = 12(x - 9)⁸ + 49
Which gives;
h(x) = 12(x - 9)⁸ + 49 = 12(x⁸ - 72x⁷ + 2268x⁶ - 40824x⁵ + 459270x⁴ -3306744x³ + 14880348x² - 38263752x + 43046721) + 49
For x = 1, we get;
h(x) = 201326641
When we replace x by -x, we get;
h(x) = 12(-x - 9)⁸ + 49 = 12(x⁸ + 72x⁷ + 2268x⁶ + 40824x⁵ + 459270x⁴ + 3306744x³ + 14880348x² + 38263752x + 43046721) + 49
For x = 1, we get;
h(x) = 1200000049
Therefore a translation 9 units to the left will result in a function that is neither even nor odd.

In a football game, Jim's team gained 7 yards on the first play, lost 2 yards on the second play, and lost 10 yards on the third play. How many total yards did Jim's team gain or lose after three plays?
Answer:
team loss after three games is 5.
Step-by-step explanation:
we will use positive sign for gain and negative sign for loss.
Given
Jim's team gained 7 yards on the first play
gain of yards = +7
lost 2 yards on the second play
loss of yards = -2
lost 10 yards on the third play
loss of yards = -10
Total yards gain or lost by Jim's team = +7 + (- 2) + ( - 10)
Total yards gain or lost by Jim's team = +7 -2 -10 = -5
sine sign is negative, it means there is loss and the net loss is 7 yards.
Thus, team loss after three games is 5.

Hey There!!
∠ABC ≅ ∠DEC
∠DEC = ∠GEF
thus:
∠ABC = ∠GEF
∠GFE ≅ ∠DCE
∠DCE = ∠ACB
thus:
∠ACB = ∠GFE
If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°.
Thus: ΔABC ∼ ΔGEF by AA similar triangle postulate.

Currently, your plane is cruising at an altitude of 33,000 feet and holding steady. You are instructed from the airline control tower that you need to get to a crusing altitude either below 31,000 or above 35,000 feet. If your plane can comfortably climb at an average rate of 800 feet per minute and descend at an average rate of 500 feet per minute, what is the range of times (in minutes) it will take your plane to be in the instructed cruising altitude?
Answer:
The range of time it would take the plane to be in the instructed area is 2.5 minutes to 4 minutes.
Step-by-step explanation:
The given parameters are;
The current altitude of the plane = 33,000 feet
The required altitude of the plane = Below 31,000 or above 35,000 feet
The average climbing speed of the plane = 800 feet per minute
The average descending speed of the plane = 500 feet per minute
The difference in the current and required altitudes are;
For climbing we have 35,000 feet - 33,000 feet = 2,000 feet
For descending we have 33,000 feet - 31,000 feet = 2,000 feet
Speed = Distance/Time
∴ Time = Distance/Speed
Based on the climbing and descending rate, we have;
The time it would take to climb 2,000 feet is t = 2000 feet/(800 feet/minute) = 2.5 minutes
The time it would take to descend 2,000 feet is t = 2000 feet/(500 feet/minute) = 4 minutes
The range of time it would take the plane to be in the instructed area is therefore;
Time for descending to time for ascending, which is 2.5 minutes to 4 minutes.
The range of time it would take the plane to be in the instructed area = 2.5 minutes to 4 minutes.

x = - 11Step-by-step explanation:
[tex] \frac{4}{x + 2} = \frac{12}{2x - 5} [/tex]Cross multiply
That's
4( 2x - 5) = 12( x + 2)
Expand the terms in the bracket
That's
8x - 20 = 12x + 24
Group like terms
8x - 12x = 24 + 20
- 4x = 44
Divide both sides by - 4
We have the final answer as
x = - 11Hope this helps you
Answer: x = -11
Step-by-step explanation:
First Cross product to reduce it
4(2x-5) = 12(x+2) Now apply the distributive property on each sides and solve for x.
8x - 20 = 12x + 24 Add 20 to both sides
+20 +20
8x = 12x +44 subtract 12x from both sides
-12x -12x
-4x = 44 Divide both sides by -4
x = -11
Which of the following best defines an angle?
O A corner of a figure like a triangle or square
O Any object that has a vertex,
OTwo rays that share a common endpoint
O The point where two line segments intersect
Answer:
Third option
Step-by-step explanation:
The first definition is not as broad as it should be, therefore, while an angle does meet that criteria, it's not a general definition, hence, it is incorrect. The second one is incorrect as well because a parabola has a vertex, and it is certainly not an angle. This definition is not specific enough, so it will be eliminated. The last one is again, too specific. The third one is the best answer because it is broad enough while still being specific.

Which expressions are equivalent to − 6 + 3 ( 2 + ( − 4 t ) ) −6+3(2+(−4t))minus, 6, plus, 3, left parenthesis, 2, plus, left parenthesis, minus, 4, t, right parenthesis, right parenthesis ?
Answer:
-12tStep-by-step explanation:
Given the expression − 6 + 3 ( 2 + ( − 4 t ) ), to get the equivalent expression, the following steps must be followed;
Step 1: Multiply the signs inside the parenthesis
= − 6 + 3 ( 2 + ( − 4 t ) )
= -6+3(2-4t)
Step 2: Open up the parenthesis
= -6 + 3(2)+3(-4t)
= -6 + 6 - 12t
Step 3: Simplify the resulting expression by taking the diffrence between -6 and 6:
= 0 - 12t
= -12t
Hence the equivalent expression is -12t
Answer:

23=9-4x I don’t understand this equation
Answer:
= -7/2
Step-by-step explanation:
What the equation is saying is that 9 - 4x = 23.
x means some number we don't know, but the value of x should be able to satisfy 9 - 4x = 23
In order to find what x may be we must separate it so it is by itself.
First we subtract 9 from both sides,
9 - 9 - 4x = 23 - 9
-4x = 14
Now we divide both sides by -4 to get x,
-4x/-4 = 14/-4
x = -14/4 = -7/2
Answer:
x= -3.5 or x=-7/2
Step-by-step explanation:
We are given the equation:
23 = 9 - 4x
We want to solve for the variable, x. Therefore, we must isolate x on one side of the equation.
First, let's rearrange the equation.
23 = 9 -4x
23= -4x +9
9 is being added to -4x. The inverse of addition is subtraction. Subtract 9 from both sides of the equation.
23-9= -4x +9-9
23-9= -4x
14 = -4x
-4 and x are being multiplied. The inverse of multiplication is division. Divide both sides of the equation by -4.
14/-4= -4x/-4
14/-4= x
-7/2=x
-3.5=x
Let's check our solution. Plug -3.5 in for x and solve.
23=9-4x (x=-3.5)
23= 9-4(-3.5)
23= 9- -14
23= 9+14
The statement above is true, so we know our solution is correct.
The solution to the equation is x= -3.5 or x= -7/2

Use dimensional analysis to convert the measurements. A dwarf sea horse swims at a rate of 49.68 feet per hour. Convert this speed to inches per minute. The speed is inches per minute.
Answer:
9.936in/minStep-by-step explanation:
Given the rate at which a dwarf sea horse swims expressed as 49.68 feet per hour, to convert the speed to inches per minutes, the following conversion factors must be used.
1 foot = 12inches and 1 hour = 60 minutes
49.68 feet per hour can also be written as [tex]\dfrac{49.68* 1 ft}{1 hour}[/tex]
On conversion:
[tex]= \dfrac{49.68* 1 ft}{1 hour} * \dfrac{1 hour * 12 in}{1 ft * 60min} \\\\= \dfrac{49.68* 12in}{60 min} \\\\= \dfrac{596.16in}{60 min}\\\\= 9.936 in/min[/tex]
Hence the speed expressed in inches per minute is 9.936in/min

Answer:
The number is 3
Step-by-step explanation:
Let the number be x
Four times a number = 4 *x = 4x
Three more than four times a number = 4x + 3
4x +3 = 15
Subtract 3 from both sides
4x + 3 - 3 = 15 -3
4x = 12
Divide both sides by 4
4x/4x = 12/4

Multiply both sides of the second equation by 100 to get rid of the decimals:
0.05n + 0.10d = 1.50
==> 5n + 10d = 150
Multiply both sides of the first equation by -5:
n + d = 21
==> -5n - 5d = -105
Add the two equations together:
(5n + 10d) + (-5n - 5d) = 150 + (-105)
Notice that the terms containing n get eliminated and we can solve for d :
(5n - 5n) + (10d - 5d) = 150 - 105
5d = 45
d = 45/5 = 9
Plug this into either original equation to solve for n. Doing this with the first equation is easiest:
n + 9 = 21
n = 21 - 9 = 12
