I think the correct answer from the choices listed above is the first option. The equation (m + 5)(m - 9) = 0 has <span>solutions of m = -5 and m = 9. Hope this answers the question. Have a nice day. Feel free to ask more questions. Thank you.</span>

Answer:

A. $(m+5)(m-9)=0$

Step-by-step explanation:

We have been given that an equation has solutions of $m=-5$ and $m=9$ . We are asked to the equation, which represents these solutions.

Let us check our given choices:

A. $(m+5)(m-9)=0$

Using zero product property, we will get:

$m+5=0\text{ (or) }m-9=0$

$m+5-5=0-5\text{ (or) }m-9+9=0+9$

$m=-5\text{ (or) }m=9$

Therefore, option A is the correct choice.

Graph 3x + 4y = -10

cricket20 [7]

First, isolate y on one side to find some information about the graph.

3x+4y=-10
4y=-10-3x
y=(-10-3x)/4

Now find out the x and y intercepts of this equation;

(0)=(-10-3x)/4
4x0=-10-3x
0=-10-3x
3x=-10
x=-10/3 or -3.3333 (x-intercept)

y=(-10-3(0))/4
4y=-10
y=-10/4 or -5/2 = -2.5 (y-intercept)

Plot these points onto your graph and connect the lines.

I have attached a graph below, I'm sorry I couldn't do it on paper.

Hope I helped :)
