The answer for y=22-4x+6 is 0=22-4x+6
And apart of it 4x=28and x=7
And for y=x+2 is 0=x+2
Apart of it -x=2 and x=-2
Answer:
D
Step-by-step explanation:
Given
x = 6 - x² ( subtract 6 - x² from both sides )
x² + x - 6 = 0 ← in standard form
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)
The factors are + 3 and - 2, since
- 3 × 2 = - 6 and 3 - 2 = + 1, thus
(x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
Sum of solutions = - 3 + 2 = - 1 → D
The line with the arrows is where y=-3 is
Just plug in a calculator 336/7 and you should get a non decimal answer.
X=6
12x-30=8x-6 simplify and solve :)
