B because 20- 16 equals 4 I guess
3 and 4! Because 3x4=12 and 4x3= 12! Mark me brainliest so I can help more people !
Answer:
Step-by-step explanation:
The vertex would be the highest/lowest point so lets factor this first
when we factor we get
2(x^2+6x+8)
2(x+4) (x+2)
Using zero product property we find the 2 x values and x intercepts are
-4 and -2
the middle point of these points is -3
Substitute -3 for x and solve
2(-3+4) (-3+2)
2 * 1 * -1
2*-1
-2
(-3,-2) is the vertex
Answer:
6
Step-by-step explanation:
First, subtract 9 on both sides:
d+9-9=15-9
d=6

Answer:
The answer is
<h2>
![y + 9 = - 2(x - 10)](https://tex.z-dn.net/?f=y%20%2B%209%20%3D%20%20-%202%28x%20-%2010%29)
</h2>
Step-by-step explanation:
To find the equation of a line given a point and slope we use the formula
<h3>y - y1 = m(x - x1)</h3>
where
m is the slope
( x1 , y1) is the point
From the question
Slope / m = - 2
The point is ( 10, - 9)
Substitute the values into the above formula
That's the final answer is
<h3>
![y + 9 = - 2(x - 10)](https://tex.z-dn.net/?f=y%20%2B%209%20%3D%20%20-%202%28x%20-%2010%29%20)
