To find an equation with specific roots, we have an equation if the form y=A(x-h)(x-k) where the roots are h and k. this is because when you plug in x=h or x=k, you get y=A(h-h)(h-k)=A(0)(h-k) = 0

so for the first question, we have
y=A(x-(-10))(x-(-6))=A(x+10)(x+6)

but the vertex must be at (-8,-8), which means when x=-8, then y=-8

plugging this in we get:
-8=A(-8+10)(-8+6)
-8=A(2)(-2)
-8=A(-4)
A=2

so our final answer is
y=2(x+10)(x+6)

using the same method the answer so the second one is:

y=-(x-2)(x-4)

I would really appreciate help

Check your y-intercept on the graph, it is at 3. Now go up two units and then move three units to the right you will see that it lands on a point. This is called rise/run. The shading goes above the line so that means you will use this symbol: >. Also it is a dotted line. So your inequality would be:
y > 2/3x + 3
I hope this helps love! :)

Mazyrski [523]
All you would have to do is look at the 2 in the place of the thousands which equals 2000, then look at the 2 that is in the place of the tens, which equals 20, so (this might get complicated) 2000/20 is... (If you need more help just tell me)
