Answer:
-1.25
Step-by-step explanation:
The change in position for x is -5, the change in position for y is 4, -5/4 = -1.25
Polynomials are equations that uses variables and several terms
The polynomial in standard form is f(x) = x^2 - x -20
<h3>How to determine the polynomial</h3>
The polynomial has 2 zeros.
So, the form of the polynomial is:
f(x) = a(x - x1)(x - x2)
The zeros of the polynomial are 5 and -4.
So, the equation becomes
f(x) = a(x - 5)(x + 4)
The value of a = 1.
So, we have;
f(x) = 1(x - 5)(x + 4)
This gives
f(x) = (x - 5)(x + 4)
Expand
f(x) = x^2 - x -20
Hence, the polynomial in standard form is f(x) = x^2 - x -20

Answer:
the graphs are blurry, sorry :c
Step-by-step explanation:
The first thing we must do for this case is to look for the real dimensions.
We have then:
(3) * (4) = 12 feet
(4-1 / 2) * (4) = 18 feet
We are now looking for the room area:
(12) * (18) = 216 feet ^ 2
We consider the following conversion:
1 yard = 3 feet
Applying the conversion:
(216) * (1/3) ^ 2 = 24 yd ^ 2
The total cost will then be:
(24) * (15) = 360 $
Answer:
it would cost to install the carpet about:
360 $
