Each was 10 inches because she had 95 and 95-15=40 divided by 4 = 10
The systems will intersect at (1,-4), and i think the system has infinite solutions (not sure)
512=2w^2 is the best answer
Answer:
s=8
Step-by-step explanation:
lmk if you want an in depth explanation
So anytime we have a slope and want to find the slope of a perpendicular line, we just have to remember a perpendicular line's slope is the negative reciprocal (reciprocal means flip the fraction). So if we had a slope of 3/4, the slope perpendicular to it would be - 4/3.
First we need to find our slope, to do this we take the change in y over the change in x like so:
(15-12)/(4-7) = - 3/4
The slope perpendicular to this is 4/3.
