If f(x)=-7x+1 and g(x) =-5x+3 , what is (f+g)(x)? A.2x+2
B.35x+3
C.-2x-2
D.-12x+4

the answer is c

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
