Answer: The number 0
x^2 + 8x - 4 = x^2 + 8
8x - 4 = 8 ... subtract x^2 from both sides
8x = 12 .... add 4 to both sides
x = 12/8 .... divide both sides by 8
x = 3/2 ... reduce
x = 1.5 .... convert to decimal form
Now plug x = 1.5 into the expression 2x-3 and simplify
2x-3 = 2*1.5-3 = 3-3 = 0 which is the answer
28% x 358 = 28/100 x 358 =<u> 100 </u>7th graders have iphone

Answer:
The answer is 8
Step-by-step explanation:
You set the equation 9n=8n+8
Subtract 9n-8n
n=8
Y=ax+b
a... slope
b... interception on the line y
you get the equation y=-1/2 *x + 12
