Answer:
{x|x¥8} is the answer to the question
Hello from MrBillDoesMath!
Answer:
x = 8, x = -4
Discussion:
5 | x - 2| = 30 => divide both sides by 5
|x -2| = 30/5 = 6 => |x-2| = 6
(x-2) = 6 => x = 2 +6
x = 8
or
(x-2) = -6 => x = 2 + -6
x = -4
Thank you,

A. He will have to buy 200 copies
B. He will have to pay $60 for the copies plus the %6 tax which would be a total of $63.60
Answer:
a) parabola opens upwards
b) y-intercept y = 2
c) x₁ = 1 x₂ = 2
Step-by-step explanation:
y = x² - 3x + 2
This parabola is open upwards since the coefficient of x² is positive (1)
b) y-intercept is when x = 0 then
y = (0)² - 3*(0) + 2
y-intercept y = 2
to determine zeros, we can proceed as follows
x² - 3x + 2 = 0
Factoring that xpression
( x -1 ) * ( x - 2 ) = 0
Then either x- 1 = 0 and x₁ = 1 or
x - 2 = 0 and x₂ = 2
