Answer:
(2x+1) (2x-7)
Step-by-step explanation:
Multiply the coefficient of the first term by the constant 4 • -7 = -28
Find two factors of -28 whose sum equals the coefficient of the middle term, which is -12
( -28 + 1 = -27
-14 + 2 = -12 )
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and 2
4x2 - 14x + 2x - 7
Add up the first 2 terms, pulling out like factors :
2x • (2x-7)
Add up the last 2 terms, pulling out common factors :
1 • (2x-7)
Add up the four terms :
(2x+1) • (2x-7)
Answer:
2000
Step-by-step explanation:
1600 is 100% - 20% = 80% of the original price.
So it is 4/5 of the original price.
So, the marked price is 1600 * 5/4 = 2000
Answer:
Your answer is 3,947 ÷ 45 = 87 r 32

The statement is false, because -2 is larger than -3.
<h3>Is the statement true?</h3>
We know that -3 is a lower bound for the real zeros of f(x).
So, if we define k as the smallest real zero of f(x), we have:
-3 < k.
Then we can take, for example, k = -2.5
That is an allowed value for the real zero.
In that case, -2 is not a lower bound, because is false that:
-2 < k = -2.5
Then if -3 is a lower bound for the real zeros of f(x), we can't assume that -2 is also a lower bound (because -2 is larger than -3).

Answer:
A) 1/20
B) H = x/20
C) 9.5 in
Step-by-step explanation:
A) Slope is the ratio of rise to run, so is ...
slope = rise/run = (1 in)/(20 in)
slope = 1/20
__
B) The maximum height is 1/20 of the horizontal distance, so ...
H = (1/20)x
__
C) Using x=190 in the above formula, ...
H = (190 in)/20 = 9.5 in
The ramp will reach a height of 9.5 inches.
