If the dealership advertises a 10% discount and a factory rebate of $1500. Then the function S for the cost of the new car will be given below.
S = 0.90p - 15000
<h3>What is the percentage?</h3>
The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
The suggested retail price for a new car is in p dollars.
The dealership advertises a 10% discount and a factory rebate of $1500.
Write a function S in terms of p, representing the cost of the car after receiving the dealership discount will be
The amount of a car after discount will be
A = 0.90 p
And the factory gives a rebate of $ 1,500. Then the function S will be given as
S = 0.90 p - 1500

Answer:
- rewrite: 2x^2 +5x +20x +50
- factored: (x +10)(2x +5)
Step-by-step explanation:
I find this approach the most straightforward of the various ways that trinomial factoring is explained or diagramed.
You want two factors of "ac" that have a total of "b". Here, that means you want factors of 2·50 = 100 that have a total of 25. It is helpful to know your times tables.
100 = 1·100 = 2·50 = 4·25 = 5·20 = 10·10
The sums of these factor pairs are 101, 52, 29, 25, and 20. We want the pair with a sum of 25, so that's 5 and 20.
The trinomial can be rewritten using these factors as ...
2x^2 +5x +20x +50
Then it can be factored by grouping consecutive pairs:
(2x^2 +5x) +(20x +50) = x(2x +5) +10(2x +5) = (x +10)(2x +5)

<em>Additional comment</em>
It doesn't matter which of the factors of the pair you write first. If our rewrite were ...
2x^2 +20x +5x +50
Then the grouping and factoring would be (2x^2 +20x) +(5x +50)
= 2x(x +10) +5(x +10) = (2x +5)(x +10) . . . . . same factoring

Answer:
Step-by-step explanation:
Add the 2 equations
-7x+8x = 13-14
x=-1
7-y=13
-y = 6
y=-6
