Subtract 10x
10x + y = -19
10x + 3y = -17
You would get:
-2y = -2
Two negatives make a positive number! Divide
y = 1
Plug in
10x + (1) = -19
10x = -20
Divide
x = -2
Your solutions are
x = -2
y = 1
Natural, Whole, and Integers. Hopefully I helped :)
B. 9 I think because it looks like it is bisected in the middle to cut into two equal parts. Please correct me if I am wrong. Thanks.
You factor the numerator and denominator and cancel the common factors. So maybe that should help you
Answer:
D. (x - 2)(x + 2)
Step-by-step explanation:
Look at the graph, when y = 0, x = - 2 and x = 2, vertex = -4
OK so x = -2 means x + 2 = 0
and x = 2, means x - 2 = 0
So
answer :D. (x - 2)(x + 2)
