Solving <span>8x-5y=10 for y helps us to identify the y-intercept:
-5y = -8x + 10. Dividing both sides by -5, we get (8/5)x -2. Therefore, y = (8/5)x - 2; the y-intercept is (0,-2).
The equation </span><span>-6x-7y=-6 can be solved for its slope in the same manner.
7y = -6x + 6; then y = (-6/7)x + 6/7. Its slope is -7/6. A line perpendicular to this line has slope equal to the negative reciprocal of -7/6, which is 6/7.
So, using the slope-intercept form, y = mx + b becomes y = (6/7)x -2.</span>
Y=16x+7
the x represents the number of memberships the 16 represents the cost of a membership and the 7 represents the additional cost.
Answer:30 mi
3s = 2.5(s+2)
3s = 2.5s + 5
3s - 2.5s = 5
.5s = 5
s = 5/.5
s = 10 mph to the beach

Confirm this by finding the actual distance each way, should be the same
3*10 = 30 mi
Step-by-step explanation:
Answer:
A = 615.75
cost = $107.08
Step-by-step explanation:
the training area = (28/2)^2*pi
training area = 615.75 square feet
615.75/5.75 = 107.08
$107.08
A.0 I don't actually know
