Question

Solve the equation formed when f(x) = g(x). f(x) = 2.5x − 4 g(x) = −2x + 10 a. x=1 b.x=2 c. x=3 d. x=4

Answer 1

(1+1/2+1/4) divided by

Answer 2

Substitute the numbers for f(x) and g(x).
F(x)=g(x)
2.5x-4=-2x+10
Collect like terms
2.5x+2x=10+4
4.5x=14
Divide both sides by 4.5
4.5x/4.5=14/4.5
X=3.1111
Therefore, X=3, option C
