Let f(x)=−7x+1. then the expression hf(x+h)−f(x) can be written in the form ah+bx+c, where a, b, and c are constants. (note: it's possible for one or more of these constants to be 0.) find the constants.

A= 0,

B=0,

C=-7

Step-by-step explanation:

if f(x) = -7x +1 , then can be written as Ah+Bx+C

f(x+h) = -7 (x+h) +1 = -7x - 7h +1

f(x+h) - f(x) =  -7x - 7h +1 - (-7x +1) =  -7x - 7h +1 +7x -1

f(x+h) - f(x) = - 7h

= -7 =Ah+Bx+C

Ah+Bx+C = 0h+0x-7 = -7

Here:

A= 0,

B=0,

C=-7

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
