Answer:

2r

Step-by-step explanation:

2r is the answer because:

We have to switch the -3r in to +3r and positive + positive = positive.

Then we change the add sign in to subtracting sign and we subtract:

3r-5r and  it will give us:

2r

And we keep the answer positive  because our answer was a +5r so the bigger number keeps the sign  the same.

A parabola opens down and its vertex is (2, 5). What is the range of this function?
Margaret [11]

The range of the parabola that opens down and has its vertex as (2, 5) is (b) (-\infty,5]

<h3>Vertex</h3>

The vertex of a parabola can represent the minimum or the maximum point in the parabola

The vertex of the parabola is given as:

(h,k) = (2,5)

<h3>The range</h3>

The range of a function is the set of output values the function can take

From the question, we understand that the parabola opens down.

This means that, the vertex of the parabola is a maximum.

Hence, the range of the parabola is (-\infty,5]

How many solutins<br> 6x + 35 +9x =15x(x+4) -25
Sveta_85 [38]
Hi again............. I am glad to help you again.

6x + 35 + 9x = 15x(x+4) -25
6x + 35 + 9x = 15x² + 60x - 25
15x + 35 = 15x² + 60x - 25
Now, we gonna put all the common terms together
15x - 60x + 35 + 25 - 15x² =
-45x + 60 - 15x² = 0
Now, we need to factorize
-15(x-1)(x+4)=0
Set factors equal to 0
x -1 = 0 or x + 4 = 0
x = 1 or x = 4


I hope that's help !
