Answer: -10
Step-by-step explanation:
If you put it in an equation it would be -7x=7(x+20). You would then -7x to both sides to get -14x=140. Just divide -14 on both sides to isolate x. This equates to -10. If you put -10 back into the equation then it says that 70 is 7 times larger than 10. Which it is.
1. D linear
2. A quadratic
3. B exponential
4. C rational
This is a one-step equation. All you need to do is multiply the 2.5 over to the 20 to get x by itself.
x=50
Hope this helps!
Answer:
y= -4x-9
Step-by-step explanation:
first you distribute the -4: y+5= -4x-4
then you subtract 5 from both sides to isolate the variable but keep the equation balanced: y= -4x-9
Explanation
Part A
