the vertex of this parabola is at (4,-3). When the x-value is 5, the y-value is -6. what is the coefficient of the squared expre
kondaur [170]

Answer:

Step-by-step explanation:

The work form of this upside down parabola is

y=-|a|(x-h)^2+k

It's VERY important that you remember that the negative value there in front of the absolute value of a just means that the parabola is upside down. a itself will not be negative (and we know that because of the absolute value symbols there!). Filling in the x, y, h, and k values we were given allows us to solve for the |a|:

-6=-|a|(5-4)^2-3 and

-6=-|a|(1)^2-3 and

-6=-|a|1-3 and

-6=-|a|(-2) and

3 = -|a|

Again, the negative simply tells us the parabola is upside down, so the absolute value of a = 3, choice c.

Classify the equation as having one solution no solution or infinite solution
Art [367]

Answer:

no solution

Step-by-step explanation:

4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4

36x + 16 = 36x - 7  ( subtract 16 from both sides )

36x = 36x - 23 ( subtract 36x from both sides )

0 = - 23 ← False statement

This indicates the equation has no solution
