What is the result of adding these two
equations?
2x + 7y= 4
- 2x – 8y = -2

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x

What is the inverse of the function f(x) = 2x + 1?

Will mark ! (10 points also! ) if x varies inversely with y and x =6 when y= 10, find y when x=8 a. y=4.8 b. y=7.5 c. y=40/3 d. y=4/15
