Answer:
Step-by-step explanation:
<u>Given </u>
- f(x) = x + 4 and
- g(x) = x + 7
<u>Find (g - f)(x):</u>
- (g – f)(x) =
- g(x) - f(x) =
- x + 7 - x - 4 =
- 3

Answer:
option C
c.
least: $101
greatest: $1001
Step-by-step explanation:
A radio station advertises a contest with ten cash prizes totaling $5510. There is to be a $100 difference between each successive prize.
Sum of 10 prizes = 5510
100 is the difference. there is a common difference d=100
So its a arithmetic sequence
the sum formula for arithmetic sequence is

Sn = 5510, n=10 n d= 100 we need to find out first term a1

5510 = 5 (2a1 + 900)
5510 = 10a1 + 4500
Subtract 4500 on both sides
1010= 10a1
divide by 10 on both sides
a1 = 101
so first term that is least term is 101
To find out greatest term we use formula

a(10) = 101 + (10-1)100
= 101 + 900= 1001
greatest is 1001
