Answer:
c. f(x) = (x + 4)(x - 1)
Step-by-step explanation:
Since you're familiar with the product of two binomials:
(x +a)(x +b) = x² + (a+b)x + ab
you know that the constants in the binomial factors must ...
- have a product of -4
- have a sum of +3
__
All of the choices except B have binomial constants that have a product of -4.
In order, the sums of the remaining choices are ...
A: 1-4 = -3
C: 4-1 = 3 . . . . this is the correct choice
D: -2+2 = 0
5 times a number plus two is 17
5(x) + 2 = 17
isolate the x, do the opposite of PEMDAS
(Note: What you do to one side you do to the other, because of equal sign)
5x + 2 (-2) = 17 (-2)
5x = 15
5x/5 = 15/5
x = 3
hope this helps
Answer:
u should redder the reader about the
formulas as it is a direct question
$6.48- $6.00= $.48
.48÷ 6.0= 0.08
0.08 = 8%
tax rate is 8%
Answer:
.85
Step-by-step explanation:
Price she would have to pay =
(Price on Tag (Original Price)) - (Cost Discount) =
(Price on Tag) - (15%)(Price on Tag) =
(100%)(Price on Tag) - (15%)(Price on Tag) =
(100% - 15%)(Price on Tag) =
85% * (Price on Tag) =
.85 * (Price on Tag),
so .85 is the answer.
