Answer:
e. 2x - 7y = 31.
Step-by-step explanation:
If you want a line parallel to the equation, the line must have the same slope.
2x - 7y = 9
-7y = -2x + 9
y = 2/7x - 9/7
You are looking for a line where the slope is 2/7.
a. Slope is 7/2.
b. Slope is -7/2.
c. Slope is 7/2.
d. Slope is...
y + 2 = 3/4x + 3
y = 3/4x + 1
Slope is 3/4.
e. Slope is -2/-7, which is 2/7. Just make sure to check whether it passes through (5, -3) by substituting those points into the equation.
2 * 5 - 7 * -3 = 31
10 --21 = 31
10 + 21 = 31
And there's your answer: e.

To find this answer multiply the cost of the ice cream by 18%/100, or .18
$154 x .18 = $27.72

PART A:
The x-intercept at 0 shows the location where the ball was kicked. The x-intercept at x = 16 shows the location where the ball hit the ground.
The maximum value represents the highest point of the ball.
The interval where the function is increasing is 0<x<8. Between this interval, the height of the ball measured from the ground is increasing.
The interval where the function is decreasing is 0<x<16. Between this interval, the height of the ball is decreasing.
PART B:
Reading from the graph
When x = 8, y = 10 ⇒ let this be x₁ = 8 and y₁ = 10
When x = 13, y = 6 ⇒ let this be x₂ = 13 and y₂ = 6
The rate of change = (y₂-y₁) / (x₂-x₁)
The rate of change = (6 - 10) / (13 - 8)
The rate of change = -4 / 5 = -(4/5)
You use the distance distance formula d √︎(x₂-x₁)+(y₂-y₁) on this as well as y=mx+b.
With mx+b you find your second set of coordinates. With the distance formula you get your square root.
So y=-3x+10 well send you 10 up the y intercept the, neg 3 down, and positive one across the x axis.
This gives you your second set of coordinates (1,7) to go with your first set.
You apply both sets of coordinates to the distance formula. d √︎(x₂-x₁)+(y₂-y₁)
You get √︎(1-(-6))+(7-8)
Then √︎7-1
Finally √︎6
And √︎6 is between 2*2 and 3*3
Rough guess, the Sq root of 6 is 2.449 or rounded to the hundredth 2.45
