Write the equation in vertex form of the parabola with the vertex (-4,-4) that goes through the point (-2,-16)

Brrunno [24]

Answer:

$- 3(x + 4) {}^{2} - 4$

Step-by-step explanation:

Vertex form is

$a(x - h) {}^{2} + k = f(x)$

We know that h and k are both -4. Let x be -2 and y be -16.

$a( - 2 + 4) {}^{2} - 4 = - 16$

$a(2) {}^{2} - 4 = - 16$

$4a - 4 = - 16$

$4a = - 12$

$a = - 3$

So the equation in vertex form is

$- 3(x + 4) {}^{2} - 4$

If TU =UV and T has a coordinate of -17 and U has coordinate 2, what is the coordinate of V?

Alex787 [66]

Step-by-step explanation:

this is one-dimensional ? everything just on one number line ?

TU = 2 - -17 = 2 + 17 = 19

TU is 19 units long (17 units on the negative side, and 2 units on the positive side of the number line).

therefore, to make TU = UV a true statement, UV has also to be 19 units long.

as U = 2,

V = U + UV = 2 + 19 = 21
