What is y=1/2x+4 in standard form?
===========================================
Explanation:
Multiply both sides by 2 to clear out the fraction
y = (1/2)x+4
2y = 2[ (1/2)x + 4 ]
2y = 2*(1/2)x + 2*4
2y = x + 8
Then move the x term over to the left side
2y = x+8
2y-x = 8
-x+2y = 8
Optionally we can multiply both sides by -1
-x+2y = 8
-1*(-x+2y) = -1*8
x-2y = -8
This is in standard form Ax+By = C with A = 1, B = -2, C = -8
The reason why I multiplied both sides by -1 was to make A > 0 which is what some textbooks use as convention. Of course -x+2y = 8 is equally valid too.
AC = 22, BC = x + 14, and AB = x + 10.
Find x.
Hi there! :)
Answer:
[tex]\huge\boxed{x = -1}[/tex]
Given:
AC = 22
BC = x + 14
AB + x + 10
AC is equivalent to AB + BC, therefore:
AC = AB + BC
Substitute in the expressions:
22 = (x + 10) + (x + 14)
Combine like terms:
22 = 2x + 24
Subtract 24 from both sides:
-2 = 2x
Divide both sides by 2:
x = -1
Given : AC = 22, BC = x + 14, and AB = x + 10.
[tex]\rule{130}1[/tex]
Solution :
[tex]:\implies\sf AB + BC = AC\:\:\:\:\Bigg\lgroup \bf{Segment\: addition\: postulate}\Bigg\rgroup \\\\\\:\implies\sf (x + 10) + (x + 14) = 22\:\:\:\:\Bigg\lgroup \bf{Substitution}\Bigg\rgroup\\\\\\:\implies\sf 2x + 24 = 22\:\:\:\:\Bigg\lgroup \bf{Simplify\:(added\:like\:term)}\Bigg\rgroup\\\\\\:\implies\sf 2x = -2\\\\\\:\implies\sf x = \dfrac{-2}{2}\\\\\\:\implies\underline{\boxed{\pink{\sf x = -1}}} [/tex]

Step-by-step explanation:
Janet wants to calculate the time it takes to earn a certain amount of
interest on a principal amount in an investment with simple interest. What
equation can she use?
Answer:
The time it takes to earn an amount A with a given principal P invested for a time period t is t = (A/P - 1)/r
Step-by-step explanation:
In order to calculate the time it would take to earn a certain amount of interest on a principal amount in an investment with simple interest, we use the simple interest formula as follows;
A = P·(1 + r·t)
A = The final amount after the number of periods of investment
P = The principal or initial amount
r = The interest rate per period
t = The number of the time periods
Therefore, the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest is fount by making t the subject of the above equation, which is given as follows;
A/P = 1 + rt
rt = A/P - 1
t = (A/P - 1)/r
Therefore, the time it takes to earn an amount A with a given principal P invested for a time period t is given by t = (A/P - 1)/r.

How to do this question plz answer my question step by step plzz plz plz plz
Answer:
40°, 95°, 105°, and 160°
Step-by-step explanation:
Let the smallest angle be x.
Measures of the 3 angles can be expressed as:
[tex] x + 55 [/tex]
[tex] x + 65 [/tex]
[tex] x + 120 [/tex]
The sum of all angles in a quadrilateral = 360°.
Therefore, [tex] (x + 55) + (x + 65) + (x + 120) = 360 [/tex]
Solve for x
[tex] x + 55 + x + 65 + x + 120 = 360 [/tex]
[tex] 3x + 240 = 360 [/tex]
[tex] 3x + 240 - 240 = 360 - 240 [/tex]
[tex] 3x = 120 [/tex]
[tex] \frac{3x}{3} = \frac{120}{3} [/tex]
[tex] x = 40 [/tex]
The smallest angle = 40°
Plug in the value of x in the earlier stated expressions to find the measure of the other angles:
[tex] x + 55 = 40 + 55 = 95 [/tex]
[tex] x + 65 = 40 + 65 = 105 [/tex]
[tex] x + 120 = 40 + 120 = 160 [/tex]

= -4.
Think of these numbers as 'directed' numbers - the numbers depend on the direction.
If we have a thermometer and the temperature reads 1 degree and the temperature drops, the mercury travels down ( negative direction) by 5 units. . It goes down 1 degree to reach 0 then another 4 degrees to reach -4,
1 - 5 = -4.
1 rectangle has a circumference of 72cm. If you reduce the width by 6cm and keep the same length, the area will decrease by 120cm2. Calculate the length and width of the rectangle. Detail solution pls
Answer
the length is 20 cm and breadth is 16cm
Step-by-step explanation:
let, 2(a+b)= 72( as its the formulae of circumference)
here a is the length and b is the breadth
now total area is ab
according to the question
a(b-6)= ab-120
or -6a= - 120
so length is 20 cm
now by putting the value in the 1st eq we get
2(a+b)=72
or(a+b)=36
or 20+b=36
so breadth is 16 cm.
length is 20cm and breadth is 16 cm

The one that does not belong contains fewer points.
The one that does not belong has a different number of dimensions.
Answer:
The one that does not belong has a different number of dimensions.
Step-by-step explanation:
Given list consists of:
a line segment (AB)a plane (CDE)a line (FG)a ray (HI)Three of them have one dimension but the plane has two dimensions,
therefore the plane in the list does not belong with the other three.

Although they haven’t met before, they begin talking and realize they are all are going along the same route to get to their respective destinations. Alice’s destination is 20 miles away, Ben’s destination is 30 miles away, and Calvin’s destination is 40 miles away. The taxi costs $2 per mile with tip included. The fare is the same no matter the number of passengers. Provide an argument as to how much each person should pay, if the three share a cab to their respective destinations
Answer: $17.78; 26.67; 35.56
Step-by-step explanation:
Given the following information.:
Price of cab = $2 per mile , irrespective of the number of passengers.
Alice's destination = 20 miles
Ben's destination = 30 miles
Calvin's destination = 40 miles
If the three share a cab, the cab fee will be (cost per mile * number of miles of the farthest destination).
($2 * 40) = $80
Let price = a, for 20 miles
Ben's mile = 30 miles = 1.5 times Alice's miles, then Ben's pay = (1.5a)
Calvin's mile = 40 miles = 2 times Alice's miles, then Calvin's pay = (2a)
Thus,
a + 1.5a + 2a = $80
4.5a = $80
a = $80 / 4. 5
a = $17.78
Ben's pay = 1.5a = $26.67
Calvin's pay = 2a = $35.56

The base of the carton is 5*8 = 40 square cm. The height of the milk is 12 cm, so the milk takes up 40*12 = 480 cubic cm of volume. Imagine a rectangular block with dimensions 5, 8 and 12. The volume would be 480.
The carton is placed on its side. Specifically the orange side is flat on the table (assume the table is level). This orange face has area 8*15 = 120 square cm. It multiplies with some height h, which is the height of the milk after moving the carton, to get the volume of the milk inside.
The volume of the milk is 120h and it must be equal to 480 since the amount of milk has not changed as we moved the carton (assume there are no leaks)
So,
120h = 480
120h/120 = 480/120
h = 4
The height of the milk after moving the carton is 4 cm
Log k-log(k-2)=log25
Answer:
k = [tex]\frac{25}{12}[/tex]
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log([tex]\frac{x}{y}[/tex] )
log a = log b ⇒ a = b
Given
logk - log(k - 2) = log25, then
log ([tex]\frac{k}{k-2}[/tex] ) = log25, thus
[tex]\frac{k}{k-2}[/tex] = 25 ( multiply both sides by (k - 2)
25(k - 2) = k
25k - 50 = k ( subtract k from both sides )
24k - 50 = 0 ( add 50 to both sides )
24k = 50 ( divide both sides by 24 )
k = [tex]\frac{50}{24}[/tex] = [tex]\frac{25}{12}[/tex]
The yearly attendance at a local restaurant is 48,300 and grows continuously at a rate of 6.8% each year. What is the approximate attendance at the restaurant in 18 years?
y=-x+9; (-9, ),(1, ),(5, )
Answer: (-9,18) , (1,8) and (5,4)
Step-by-step explanation:
If the x coordinate is -9 then plot it into the equation and solve for y.
y = -1(-9) + 0
y = 9 + 9
y = 18
Same for the second one plot in the value of x and solve for y
y= -1(1) + 9
y = -1 + 9
y = 8
Again same for the last one
y = -1(5) + 9
y = -5 + 9
y = 4

Answer:
x=15
Step-by-step explanation:
5x= 75 (divide)
75/5= 15
Answer: There is only one step to solve this equation; we use inverse operations to isolate the x by dividing 5 on both sides. We divide because 5 is being multiplied by x, and the inverse operation for multiplication is division.
5x/5 = x
75/5 = 15
The equation now looks like:
x = 15
x is equal to 15. This is your answer.
Lin deposited $300 in a savings account that has a 2% interest rate per year. How much is in her account after 1 year? After 2 years? Diego wants to sell his bicycle. It cost $150 when he bought it but has depreciated by 15%. How much should he sell it for? I will give brainlyies
Answer:
Step-by-step explanation:
Lin after 1 year has 300+2*300/100=300+6=306 $
after 2 years has 306+2*306/100=306+6.12=312.12$
150-15*150/100=150-22.5=127.5 $ the price for the bicycle
The value after 20 years is $ 723.514
Solution:
Formula for Amount compounded annually is as follows:
Where,
"A" is the total amount
"p" is the principal sum
"r" is the rate of interest
"n" is the number of years
From given question,
p = $ 300
r = 4.5 %
n = 20 years
Substituting the values we get,
Thus value after 20 years is $ 723.514
PART 2)
2. Given data
Cost of bicycle = $150
Depreciation = 15%
Firstly let us calculate 15% of $150
(15/100)*150 =0.15*150
= $22.5
Since the value depreciated
We will minus the the depression from the initial amount
New amount = 150-22.5=
$127.5
