Answer:
320.416
Step-by-step explanation:
I cant graph it but y is anything less that 4/5 such as 1/5,2/5,3/5,and 4/5
I hope that is what you need.
We need to convert this equation to slope-intercept form first.
We can do that by solving for y.
x - 5y = 15
<em><u>Add 5y to both sides.</u></em>
x = 5y + 15
<em><u>Subtract 15 from both sides.</u></em>
x - 15 = 5y
<em><u>Divide both sides by 5.</u></em>
y = 1/5x - 3
We now know the slope is 1/5.
The slope of the line perpendicular to the line with a slope of 1/5 is -5.
The slope of a perpendicular line is the negative reciprocal of the original slope.
Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).
The equation of the new line is y = -5x - 6.
2^3 = 8
3^2 = 9
5^2 = 25
2^5 = 32
(5^2 = 5*5 = 25)
(2^5 = 2*2*2*2*2 = 32)
The correct answer would be A, because 160/10 is getting you your unit rate, or the amount Sarah spent every week.
