4 0

Answer:

r(x) = -7

Step-by-step explanation:

r(x) = -x - 7

<u>+ 7 + 7</u>

7 = -x

<u>÷ -x ÷ -x</u>

7/-1 = x

-7 = x

The intersection of the two red rays forms a set of vertical angle pairs. In such a pair, angles opposite one another have the same measure, so the angle opposite the one labeled 93 degrees also has measure 93 degrees.

The red ray on the right together with the black ray pointing directly to the right form a pair of supplementary angles, whose measures add up to 180 degrees. This means the angle adjacent to the one labeled 128 degrees has measure 180 - 128 degrees.

In any triangle, the interior angles' measures add up to 180 degrees. So we have

? + 93 + (180 - 128) = 180

? + 93 - 128 = 0

? = 128 - 93

? = 35

Every time Jason buys 2 red marbles he buys 1 blue marble. If y = the number of red marbles Jason buys, and x = the number of bl
ahrayia [7]
If y is the red marbles and x is the blue marbles, then for every x value you would be able to multiply by 2 to get the y value... it is the equivalent of looking at is as the slope rise/run or 2/1

D is the graph that shows this relationship.  Look at the x value and multiply by 2 for the y value.

The graph of a quadratic function has roots at -3 and -7 and a vertex at (-5,4). What is the
ollegr [7]

The equation of the function in vertex form is y = -(x + 5)² + 4

<h3>What is quadratic equation?</h3>

A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .

Given that the quadratic function has roots at -3 and -7 and a vertex at (-5,4).

We need to find the equation of the function in vertex form

equation of the function in vertex form.

As per the information given in the question,

The given roots of the function are -3 and -7,

y = a (x + 3) (x + 7)

y = a (x² + 10x + 21)

y = a (x² + 10x + 25 − 4)

y = a (x² + 10x + 25) − 4a

y = a (x + 5)² − 4a

The vertex is (-5, 4),

So, a = -1.

y = -(x + 5)² + 4

Hence, y = -(x + 5)² + 4  is the equation of the function in vertex form
