Find slope. Y2-y1/x2-x1. Then y=mx+b with m being the6 slope and -7 as x. 9 is y, so then substitute, and you have b=whatever number you get. Then put it in y=-7x+what that number is for b.
Answer:
x=7
Step-by-step explanation:
4(5x-2)=2(9x+3) do everything in the parentheses
20x-8=18x+6
+8 +8
20x=18x+14
get X by itself by adding same terms
20x=18x+14
-18x -18x
2x=14 divide
/2 /2
X=7

Step-by-step explanation:
Answer:
8 m/s^2
Step-by-step explanation:
F=kA
F=force
k=constant you will use for each F=kA relation
A=acceleration
Second sentence says F=90 while A=10 (plug in and find k)
90=k(10) so k=9
We have for any (A,F) that F=9A
Last sentence F=72, what is A?
So 72=9A which means A=8 m/s^2
The ratio of a pair of corresponding sides of 1/16.
