Hi :)

Ok, well- solve the equation first, then maybe from there we will have more ideas on what to do here.

So:

(x - 6)(x + 2) = 0

Set factors equal to 0

x - 6 = 0 or x + 2 = 0

x = 0 + 6 or x = 0 - 2

x = 6 or x = -2

Now we can answer the questions....

1) For (x - 6)(x + 2) to equal 0, either (x - 6) or (x + 2) must equal 0

2) In order from least to greatest, are -2 and 6

Let me know if you have any questions. As always, it is my pleasure to help students like you!

How to determine if 3 points are collinear?

A football is kicked toward an end zone with an initial vertical velocity of 30 ft/s. The function h(t) = -16+ 30t models the he

Ulleksa [173]

Answer:

A. The football does not reach a height of 15ft

Step-by-step explanation:

Given

$h(t) = -16t^2 + 30t$

Required

Determine which of the options is true

The option illustrates the height reached by the ball.

To solve this, we make use of maximum of a function

For a function f(x)

Such that:

$f(x) = ax^2 + bx + c$ :

$f(\frac{-b}{2a}) = maximum/minimum$

i.e we first solve for $\frac{-b}{2a}$

Then substitute $\frac{-b}{2a}$ for x in $f(x) = ax^2 + bx + c$

In our case:

First we need to solve $\frac{-b}{2a}$

Then substitute $\frac{-b}{2a}$ for t in $h(t) = -16t^2 + 30t$

By comparison:

$b = 30$

$c = -16$

$\frac{-b}{2a} = \frac{-30}{2 * -16}$

$\frac{-b}{2a} = \frac{-30}{-32}$

$\frac{-b}{2a} = \frac{30}{32}$

$\frac{-b}{2a} = \frac{15}{16}$

Substitute $\frac{15}{16}$ for t in $h(t) = -16t^2 + 30t$

$h(\frac{15}{16}) = -16(\frac{15}{16})^2 + 30(\frac{15}{16})$

$h(\frac{15}{16}) = -16(\frac{225}{256}) + \frac{450}{16}$

$h(\frac{15}{16}) = -(\frac{225}{16}) + \frac{450}{16}$

$h(\frac{15}{16}) = \frac{-225 + 450}{16}$

$h(\frac{15}{16}) = \frac{225}{16}$

$h(\frac{15}{16}) = 14.0625$

This implies that the maximum height reached is 14.0625ft.

So, the option that answers the question is A because $14.0625 < 15$

Rewrite the equation in Ax+By=C form Use the integers for A, B, and C <br><br><br>y=1/2x+6

Inessa05 [86]

The equation in required form is: -x+2y = 12

Step-by-step explanation:

Given equation is:

$y = \frac{1}{2}x+6$

In order to convert the equation in $Ax+By = C$

Multiplying both sides by 2

$2y = \frac{1}{2}x * 2 + 6*2\\2y = x + 12$

subtracting x from both sides

$2y-x = x-x+12\\2y-x = 12\\-x+2y = 12$

Hence,

The equation in required form is: -x+2y = 12
