Answer:
- g(x) = x^2 – 4x – 21
- g(x) = 3x^2 – 12x – 63
- g(x) = –(x + 3)(x – 7)
Step-by-step explanation:
When r is an x-intercept of the function, (x -r) is a factor. The two given x-intercepts mean that two factors of the function are (x -(-3))(x -7). There may be a vertical scale factor that is not necessarily positive.
These factors multiply out to give ...
(x +3)(x -7) = x^2 -4x -21 . . . . . . matches the first choice
When this expression is multiplied by 3, it matches the third choice:
3(x +3)(x -7) = 3x^2 -12x -63
When the factored form is multiplied by -1, it matches the fourth choice:
-(x +3)(x -7)
It is in the the tenths and ones
Answer:
By 19% the computer was less than the original price
Step-by-step explanation:
The original price on the computer was $1500
Discount is 25%= 0.25
Discount amount = 1500 * 0.25 = 375
Discounted price = 1500 - 375 = 1125
Now 8% shipping cost to discounted price
8% = 0.08
Shipping cost = 1125 * 0.08 = 90
cost of computer with shipping cost = 1125 + 90 = 1215
Percentage less = (original cost - cost of computer now ) / original cost
= 
To get percentage we multiply by 100
0.19 * 100 = 19%
Answer:
d. 200
Step-by-step explanation:
