-32=-7x-8y slope intercept form
Answer:
y = [tex]-\frac{7}{8}[/tex]x + 4
Step-by-step explanation:
-32 = -7x - 8y
Slope-intercept: y=mx+b
First, we can add 8y on both sides so we can get u by itself.
8y - 32 = -7x
Now, we can add 32 to both sides.
8y = -7x + 32
Now, we divide 8 on both sides of the equation so we can get y by itself just like in the slope-intercept formula.
y = [tex]\frac{-7}{8}[/tex]x + [tex]\frac{32}{8}[/tex]
Lastly, we can simplify and you will have your answer.
y = [tex]-\frac{7}{8}[/tex]x + 4

Determine between which consecutive integers the real zeros of f(x) = x^3 - 2 are located.
a. between 1&2
c. between 0&1
b. between -1&0
d. between -2&-1
Answer:
Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".
Step-by-step explanation:
In order to find the zeros of a function we need to find at which values for "x" make f(x) equal to zero. Therefore we have:
[tex]f(x) = x^3 - 2 \\0 = x^3 - 2\\x^3 - 2 = 0\\x^3 = 2\\x = \sqrt[3]{2} = 1.2599[/tex]
Therefore the zeros of this function are between 1 and 2. So the correct answer is "a".
Please Hurry! What is the solution to log2_(9x)-log2_3=3?
Answer:
[tex] log_{2}(9x) - log_{2}(3) = 3 \\ 3 = log_{2}(8) or log_{2}( {2}^{3} ) \\ log_{2}( \frac{9x}{3} ) = log_{2}(8) \\ \frac{9x}{3} = 8 \\ 9x = 8 \times 3 \\ 9x = 24 \\ x = \frac{24}{9} \\ x = \frac{8}{3} \\ x = 2 \times \frac{2}{3} [/tex]
Answer:
[tex]\log _2\left(9x\right)-\log _2\left(3\right)=3 : x = \frac{8}{3}[/tex]
Decimal:
[tex]x = 2.66666...[/tex]
Step-by-step explanation:
[tex]\log _2\left(9x\right)-\log _2\left(3\right)=3[/tex]
Add [tex]log _2\left(3)[/tex] to both sides:
[tex]\log _2\left(9x\right)-\log _2\left(3\right)+\log _2\left(3\right)=3+\log _2\left(3\right)[/tex]
Simplify:
[tex]\log _2\left(9x\right)=3+\log _2\left(3\right)[/tex]
Use the logarithmic definition: If [tex]\log _a\left(b\right)=c\:\mathrm{then}\:b=a^c[/tex]
[tex]\log _2\left(9x\right)=3+\log _2\left(3\right)\quad \Rightarrow \quad \:9x=2^{3+\log _2\left(3\right)}[/tex]
[tex]9x=2^{3+\log _2\left(3\right)}[/tex]
Expand [tex]2^{3+\log _2\left(3\right)} : 24[/tex]
[tex]9x=24[/tex]
Solve: [tex]9x=24 : x = \frac{8}{3}[/tex]
[tex]x = \frac{8}{3}[/tex]
Verify solutions: [tex]x = \frac{8}{3}[/tex] : True
The solution is:
[tex]x=\frac{8}{3}[/tex]

In ΔABC, the measure of ∠C=90°, the measure of ∠A=47°, and BC = 3.5 feet. Find the length of AB to the nearest tenth of a foot.
Answer:
AB = 4.9 ft
Step-by-step explanation:
Here, we are to calculate the length of AB.
Firstly, please check the diagram of the triangle we have in the attachment.
From there we can see that what we are asked to calculate is the length of the hypotenuse(AB) while what we have is the length of the opposite and the angle.
Mathematically, when we have the opposite and the hypotenuse, the trigonometric ratio that links both is the sine
sine = opposite/hypotenuse
Sin 47 = 3.5/hypotenuse
hypotenuse = 3.5/sin 47
hypotenuse = 4.7856
To the nearest tenth of a foot AB = 4.8 ft

144f
9514 1404 393
Answer:
(d) 528 ft³
Step-by-step explanation:
The shape is that of a trapezoidal prism. The front face is a trapezoid with bases 8 ft and 14 ft, and height 6 ft. Its area is ...
A = (1/2)(b1 +b2)h = (1/2)(8 +14)(6) = 66 . . . . square feet
Then the volume is given by ...
V = Bh
where B is the area of the (trapezoidal) base, and h is the height of the prism (8 ft). Filling in the values, we find ...
V = (66 ft²)(8 ft) = 528 ft³
The pool can hold 528 ft³ of water.
The space capsule is on its way back to earth after deploying its first two parachutes falls at a speed of 100 mph what is the space capsules velocity?
Answer:
Step-by-step explanation:
Velocity is the speed of an object in a definite direction. In mechanics, velocity is a vector quantity. It requires magnitude and direction to make any sense. Velocities are expressed per unit time.
The SI unit of time is the second.
Now, suppose we need the velocity in feet per second. A simple calculation will help:
feet per second = miles per hour × 1.466667 [ in other words, one mile per hour equals 1.466667 feet per second]
For a space capsule moving at 80 miles per hour, the velocity is given by
= 100 × 1.466667
= 146.67 ft/s [feet per second]

EF is a median of trapezoid ABCD. The length of AB is 12, and the length of CD is 18. The length of BF is 4. What is the length of FC?
Answer:
Step-by-step explanation:
The diagram representing the trapezoid is shown in the attached photo. The median EF is a line segment that is half way between the 2 bases. The length of the median is the average of the two bases. Therefore,
EF = (12 + 18)/2 = 15
Two similar trapezoids are formed. They are ABFE and EFCD
By comparing both trapezoids, it means that
4/15 = FC/18
Cross multiplying, it becomes
4 × 18 = 15FC
72 = 15FC
FC = 72/15
FC = 4.8

16m
-
-
8 m
Answer:
The area of trapezoid is 36 [tex]m^2[/tex].
Step-by-step explanation:
To find the area of a trapezoid, you need this formula:
[tex]A = \frac{(a+b)}{2} \times h[/tex]
[tex]a =[/tex] long base
[tex]b =[/tex]short base
[tex]h =[/tex] altitude (height)
-Use the following measures of trapezoid for the formula:
[tex]A = \frac{(8+4)}{2} \times 6[/tex]
-Then, you solve the formula:
[tex]A = \frac{(8+4)}{2} \times 6[/tex]
[tex]A = \frac{12}{2} \times 6[/tex]
[tex]A = 6 \times 6[/tex]
[tex]A = 36[/tex]
So, therefore, the area of a trapezoid is 36 [tex]m^2[/tex].

Help! I don’t understand this and I need help! “What is the length of the missing side?” Also D was cut off but it says 90
Answer:
The missing side = 30 cm
Step-by-step explanation:
Pythagorean Theorem
a^2 + b^2 = c^2
40^2 + b^2 = 50^2
1600 + b^2 = 2500
-1600 -1600
b^2=900
square root of both sides
b=30 cm

Answer:
x =5
y = 35
Step-by-step explanation:
y = 7x
y = 3x+20
Since they both equal y, we can set them equal to each other
7x = 3x+20
Subtract 3x from each side
7x-3x = 3x+20-3x
4x= 20
Divide each side by 4
4x/4 =20/4
x = 5
Now find y
y = 7x
y = 7(5)
y = 35

If there are 13 people in club a and 20 people in club b and 25 students in total, how many people are in both clubs?
Answer:
2 students are in both clubs
Step-by-step explanation:
x = 1 student (this number may be more than the total because one student can be in 2 clubs)
Club a = 13
Club b = 20
13 + 20 = 27x
Total members of clubs - total number of students = 27x - 25 = 2
2 students are in both clubs

Alculate the amount of heat transferred when 710 grams of water warms from an initial temperature of 4.0 ºC to a final temperature of 25.0 ºC. The specific heat capacity of liquid water is 4.184 J/g ºC. Please express you answer as a number in units of kJ, and be careful about the sign (is the answer a positive or negative number?) since that shows the direction of heat flow.
Answer:
The Quantity of heat require is [tex]0.062kJ[/tex]
Step-by-step explanation:
This problem bothers on the topic of heat capacity.
Given data
mass of water m= [tex]710 grams[/tex]
converting from grams to kg we have =[tex]\frac{710}{1000} = 0.71kg[/tex]
initial temperature T1= 4°C
final temperature T2= 25°C
heat capacity of water = [tex]4.184 J/g[/tex]
The expression for the quantity of heat required is given has
[tex]Q= mc(T2-T1)[/tex]
substituting our given data we have
[tex]Q= 0.71*4.184*(25-4)\\Q= 2.97*(21)\\Q= 62.38J\\[/tex]
In kilograms we have to divide by [tex]1000[/tex]
[tex]Q= \frac{62.38}{1000} = 0.062kJ[/tex]
- Ms. McNeil buys 2.4 gallons of gasoline. The total cost is $7.56. The
equation 2.4p = 7.56 can be used to find the price p in dollars of
one gallon of gasoline. What is the price of one gallon of gasoline?
Answer:
The price of one gallon of gasoline is $3.15
Step-by-step explanation:
If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":
2.4 p = 7.56
then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:
p = 7.56/2.4
p = $3.15
so this is the price per gallon of gasoline.
