Answer:
Step-by-step explanation:
The given system is:
4x-3y=8
5x-2y=-11
We make x the subject in the top equation to get:
Plug this expression for x in the bottom equation to get
We expand to obtain
Multiply through by 4
Group similar terms
This means
Step-by-step explanation:
Option A is the correct answer
You need two sides so you can rewrite it as:
2x = 70-(14+32)
2x = 24
x = 24/2
x = 12
The height is 12in.
Hope this helps! :)
Answer:
y=2x-8
just wondering: how does summer depend on this?!?!
X^4 - 5x^2 - 36 = 0
(x^2 - 9)(x^2 + 4) = 0
(x-3)(x+3)(x-2)(x+2) = 0
x = -3, -2, 2, 3
