Answer:
Step-by-step explanation:
We want a line parallel to 3x − 4y = 7. Any such line will have an equation of the same form but a different constant.
If the new line is to pass through the point (-4, -2), replace x with -4 and y with -2. We obtain:
3(-4) − 4(-2) = -12 + 8 = -4. Thus, the desired new equation is 3x − 4y = -4.
This could also be written as 3x − 4y + 4 = 0. We could also solve this for y, obtaining:
3x + 4 = 4y, or y = (3/4)x + 1.
0.15p , p < $900
C(p) = 0.17p, $900 < p < $1,500
0.21p, p > $1,500
Create an equation for the total costs of driving x miles: 3.50 + 2.50x
since Sasha has $37, the equation would become: 3.50 + 2.50x = $37
subtract 3.50 from both sides: 2.50x = 33.50
divide 2.50 on both sides: x = 13.4
since the problem is asking for the greatest whole number of miles, you have to round down and the answer would be: 13 miles.
