The equation 2x - 4y - 8 models the relationship between x and y. What is the rate of change of y with respect tox?
Answer:
1/2Step-by-step explanation:
Given the equation 2x-4y = 8 models the relationship between x and y
The rate of change of y with respect to x is known as the slope of the line.
The standard form of equation of a line is y = mx+c where;
m is the slope
c is the intercept
Rewrite the equation in its standard form as shown:
2x-4y = 8
-4y = -2x+8
-4y/-4 = -2x/-4 + 8/-4
y = 1/2 x -2
On comparison, the slope m is 1/2
Hence the rate of change of y with respect to x is 1/2

I am thinking of a number. Its square root
is an integer. Its cube root is an integer.
Answer:
You may be thinking about 64
Step-by-step explanation:
64 = 8*8 = (2*2*2) * (2*2*2)
64 = 4*4*4 = (2*2) * (2*2) * (2*2)
Which of the following are point-slope equations of the line going through
(-4,-7) and (3, 2)? Check all that apply.
PLEASSSEEE HELP I’VE BEEN STUCK ON THIS FOR A COUPLE OF DAYS .. 15 points
Answer:
The equations of the line are
y + 7 = [tex]\frac{9}{7}[/tex] (x + 4) ⇒ B
y - 2 = [tex]\frac{9}{7}[/tex] (x - 3) ⇒ E
Step-by-step explanation:
The point-slope form of the linear equation is
[tex]y-y1=m(x-x1)[/tex] , where
m is the slope of the line(x1, y1) is a point on the lineThe rule of the slope is [tex]m=\frac{y2-y1}{x2-x1}[/tex]∵ The line passes through points (-4, -7) and (3, 2)
∴ x1 = -4 and y1 = -7
∴ x2 = 3 and y2 = 2
→ Use the rule of the slope above to find it
∵ [tex]m=\frac{2--7}{3--4}=\frac{2+7}{3+4}=\frac{9}{7}[/tex]
∴ The slope of the line is [tex]\frac{9}{7}[/tex]
→ Substitute the values of m and (x1, y1) in the form of the equation above
∵ y - -7 = [tex]\frac{9}{7}[/tex] (x - -4)
∴ y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)
∴ The equation of the line is y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)
→ Substitute the values of m and (x2, y2) in the form of the equation above
∵ y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)
∴ The equation of the line is y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)
→ Look at the answers to find the same equations
∴ Answers B and E have the same equations

A hot air balloon can hold up to 300 pounds of weight. The balloon's pilot weighs 140 pounds. How many 20-pound bags or sand can also be carried by the hot air balloon?
Answer:
8 sand bags can be carried along.
Step-by-step explanation:
First you want to subtract 300-140. That subtracts the pilots weight giving you the maximum weight capacity left. (160) Then you want to divide 160 (the weight that can be carried) by 20 (the weight of the sand bags) after doing that you will get 8. And that is how i got 8 sand bags as my answer.

Trucks must haul between 150,000 yd' and 180,000 yd of earth each day to create a new
water park near Universal Studios in Orlando, Florida. The trucks can haul 10.000 yd per day
and 120,500 yds have already been brought to the site. How many days are needed to
complete this job?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Range which must be hauled by trucks :
150,000 - 180,000 yds of earth
Haul per day = 10000 yds
Already removed = 120,500
We can express the problem as an inequality:
Using y = number of days
150,000 ≤ (10000y + 120,500) ≤ 180000
150,000 ≤ (10000y + 120,500)
150000 - 120500 ≤ 10000y
29500/10000
y = 2.95 days
10000y + 120,500 ≤ 160000
10000y ≤ 160000 - 120500
y = 39500/10000
y = 3.95
2.95 ≤ y ≤ 3.95

PLS HELP 50 points!!!! Which relation is a function?
O {(-2, 1), (-7, - 1), (2, 8), (-7, – 8)}
O {(-2, 2), (-7, 7), (-1, 1), (-8, 8)}
O {(-2, 1), (-2, 2), (-2, 7), (-2, 8)}
O {(1, -7), (2, – 8), (-2, 7), (1, 8)}
Answer:
B
Step-by-step explanation:
For a relation to be a function, it must fit the following criteria:
Each input must be matched to exactly one output. Inputs cannot repeat*. Outputs can. *If inputs do repeat, they must be equal the same output as the other inputs.So, let’s go through each of the choices.
Choice A)
In this relation, -7 repeats. It simultaneously equals -1 and -8. So, this is not a function since it’s repeating and it doesn’t equal to same.
Choice B)
In this relation, none of the inputs are repeating. Therefore, B is the corrrect answer.
Choice C)
In this relation, -2 repeats four times. And each time, it equals something different. Therefore, C is not a function.
Choice D)
Here, 1 repeats twice, equalling both -7 and 8. Since it appeared more than once and is not equal to the same thing, D is not a function.
Therefore, our answer is B.

The function y = −0.03x(x− 10) models the jump of a rabbit where x is the horizontal distance (in feet). How long is the rabbit’s jump? what is the rabbits max height?
show step plz
Answer:
x (distance) = 10, max height = .75
Step-by-step explanation:
y=-.03x(x-10)
The distance are the x intercepts: 0 and 10, where 0 is time started and 10 is time ended.
Expand the equation:
y=-.03x^2 +.3x
To find max height you find the vertex
x = -b/2a
x = -.3/-.06 = 5
Plug the x into the equation
y=.-03(5)^2 +.3(5)
y=.75
