Answer:
(3, -3)
Step-by-step explanation:
When asked to solve by elimination, you put them on top of one another, like you're going to add it.
10x + 7y = 9
-4x - 7y = 9
See that 7y? You can cancel those out because one is negative, and one is positive. So those are gone. You finish adding the rest of the numbers as usual and solve for x.
6x = 18
x = 3
Take x, and plug it into either equation to find y.
10(3) + 7y = 9
7y = -21
y = -3
(3, -3)
Hope this helped!
If H = 4, we simply plug 4 into the position of h in the expression.
48 + 25 * 4
48 + 100
148
The customer pays $148
take square root of 121, which is 11
so -12, 3, 10,
the songs are approximately 1 dollar each
80 songs times 1 dollar = 80 dollars
It depend on the center of the dilation. For example, if the point (-6,4) is the center itself, than it will remain the same.
If the dilation has the origin as center, instead, the factor 1/2 simply means that you have to divide all coordinates by 2: the point (-6,4) becomes the point (-3,2)
