The parabola equation in its vertex form is y = a(x-h)² + k , where:
a is the same as the a coefficient in the standard form;
h is the x-coordinate of the parabola vertex; and.
k is the y-coordinate of the parabola vertex.
that’s how you find it

Which expression is equivalent to 1/3(12x+6x-21)

marin [14]

Answer:

$6x-7$

Step-by-step explanation:

$\frac{1}{3} (12x + 6x -21)$

break it into pieces

$\frac{1}{3}*12x = 4x$

$\frac{1}{3}*6x=2x$

$\frac{1}{3} *-21=-7$

put it all together

*since there's no negative in front of the other numbers except 7 they're positive so you add them*

$4x + 2x - 7$

simplify

$6x - 7$

Luke is building a storage building and needs to have a slab of concrete poured. He knows the contractor charges an initial cost

kherson [118]

The answer is A.

y is the total cost, than you would need to multiply x, the number additional number of square feet, which is 3.5x. you would then add 95 dollars to the equation to represent the initial fee. So the equation would look like Y=3.5x+95.
