<u>Answer:</u>
(x, y) = (-2, 2)
<u>Step-by-step explanation:</u>
We are given the following two equations which we are to solve using the substitution method:
--- (1)
--- (2)
From equation (1):
Substituting this value of x in (2) to get:
![x = [tex]x - 2y = -6\\\\(y-4)-2y=-6\\\\-y=-6+4\\\\-y=-2](https://tex.z-dn.net/?f=x%20%3D%20%5Btex%5Dx%20-%202y%20%3D%20-6%5C%5C%5C%5C%28y-4%29-2y%3D-6%5C%5C%5C%5C-y%3D-6%2B4%5C%5C%5C%5C-y%3D-2)
[/tex]
y = 2
Substituting the value of y in (1) to get x:
x = -2
Therefore, (x, y) = (-2, 2).
You have to compute the prices of the two alternatives after
deducting discount based on the different percentage given.
First alternative: $19.99 – ($19.99 x 20%) = $15.99
Second alternative: $17 – ($17 x 10%)
= $15.30
Therefore, the alternative where
there will be a 10% off on the original price of $17 for a book is cheaper.
Answer:
(-4,6) is the vertex
Step-by-step explanation:
because it's either the lowest or highest point on the graph.
.8 percent of 200 is 1600 becaus 2000* .8=1600
16 pounds are greater than 16 ounces
