Answer:
Step-by-step explanation:
<u>It looks like</u>
<u>Cross-multiplication:</u>
- 4m(m+7) = 9*18
- 2m(m+7) = 9*9
- 2m^2 + 14m = 81
- 2m^2 + 14m - 81 = 0
Here is the quadratic equation
The slope of this equation is
3
I think it's 13. Hope this helps
Answer:
it's 1/7^2
Step-by-step explanation:
When multiply bases with exponents, as long as they are the like bases, you add the exponents. 7^3 x 7^-5 = 7^-2.
When you have a negative exponent, you can get rid of it by moving it to a fraction. put a 1 over the base and exponent and drop the negative, so 1/7^2
