Answer:
- 8
Step-by-step explanation:
Given
x² - 64 = 0 ( add 64 to both sides )
x² = 64 ( take the square root of both sides )
x = ±
= ± 8
Solutions are x = 8 and x = - 8
Answer:
A: write0,4,8,12,16,20 on the line which the answer for A is 16 divided by 4=4
B: Write 0,25,50,75,100,125,150 on the line which the answer for B is 50 divided by 2= 25
From the first equation
6x - y = 1
6x - y - 1 = 0
6x - 1 = y
Substituting we get
4x - 3(6x - 1) = -11
