Answer:
No
Step-by-step explanation:
By the factor theorem if (x + 2) is a factor of f(x) then f(- 2) = 0
f(- 2)
= 2 +
+ 32(- 2) + 32
= 2(64) - 32 - 64 + 32
= 128 - 32 - 64 + 32
= 64 ≠ 0
Hence (x + 2) is not a factor of f(x)

Answer:
y = .5x +15
The graph is a line.
The slope is .5 and the y intercept is 15. The flat fee is the y intercept and the cost per mile is the slope.
Step-by-step explanation:
The flat fee is the y intercept and the cost per mile is the slope
The total cost for the day is equal to the cost per mile * the number of miles driven plus the flat fee. Let x be the number of miles driven and y be the total cost for the day.
We can use y = mx+b
y = .5x +15
When we graph, x must be greater than 0 because we cannot drive negative miles.
The slope is .5 and the y intercept is 15. The flat fee is the y intercept and the cost per mile is the slope.

Answer:
Conrad had 56 sales on Monday , 168 sales on Tuesday and 504 sales on Wednesday.
Step-by-step explanation:
Let x be the no. of sales on Monday
We are given that On Tuesday Conrad had 3 times as many sales as on Monday.
So, Conrad had sales on Tuesday = 3x
We are also given that On Wednesday, he had 9 times as many sales as on Monday.
So, Conrad had sales on Wednesday = 9x
Over the three days, he had a total of 728 sales
So, x+3x+9x=728
13x=728
x=56
Conrad had sales on Tuesday = 3x =3(56)=168
Conrad had sales on Wednesday = 9x=9(56)=504
Hence Conrad had 56 sales on Monday , 168 sales on Tuesday and 504 sales on Wednesday.
