Question 7 (5 points)
given that f(x) = x2 – 7x-1, g(x) = 2x – 3, and h(x) = 4x – 5 find each function,
(f+ g)(x)

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
