Answer: (C) divide by 1
<u>Step-by-step explanation:</u>
when dividing by x - 1, set the expression equal to zero to find the zero. That is actually what you are dividing by:
x - 1 = 0 ⇒ x = 1
so the number outside of the synthetic division symbol is 1.
>First jump = 4.25 m
>Best jump = 1.12 * First jump
Best jump = 1.12 * (4.25 m)
Best jump = 4.76 m
>Best jump = 0.85 * Winning jump
Hence,
Winning jump = Best jump / 0.85
Winning jump = 4.76 m / 0.85
<span>Winning jump = 5.6 m</span>
Given:
Amount spent on 2 DVDs = $41.75
Sales tax = $3.15
Coupon = $1.00 off
To find:
The cost of each DVD.
Solution:
Let x be the cost of each DVD.
Then, cost of two DVDs = 2x
Amount spent of 2 DVDs = Cost of 2 DVDs + Sales tax - Coupon discount
Divide both sides by 2.
Therefore, the cost of each DVD is $19.8.

6x + 18y = 18. Let us take x = 0
6(0) + 18y = 18
0 + 18y = 18
18y = 18
y = 18/18
y = 1
(0, 1) [x = 0, y = 1]
6x + 18y = 18. Let us take y = 0
6x + 18(0) = 18
6x + 0 = 18
6x = 18
x = 18/6
x = 3
(3, 0) [x = 3, y =0]
Infinite solutions can be found for x and y
