I think the correct answer is <span>a)x in first equation
</span>
Look at the <span>first equation:
</span><span>3x + 6y = 9
</span>You can divide both sides by 3 to get:
x + 2y = 3
And then solve it for x:
x = 3 - 2y
<span>Now you can substitute x to 3-2y in the second equation
</span><span>Next you will solve the second equation for y</span>
Answer:
y = 2x^2 − 4x + 5
y = 2(x^2 − 2x) + 5
y = 2(x^2 − 2x + 1 - 1) + 5
y = 2(x^2 − 2x + 1) + 5 - 2
y = 2(x - 1)^2 + 3
x = 1 is the axis of symmetry.
Do you agree?
Answer:
7 x + y = 9
Step-by-step explanation:
It would be D because you can't have two of the same X factors with different Y outputs
