Answer:
The slope is 3.75 OR 3 3/4.
Step-by-step explanation:
So the formula for slope I am using NOW, is based on the variables I named my dimensions. WARNING: NOT SLOPE FORMULA YOU MIGHT BE USING
y = 95 - 80
x = 10 - 6
Slope Formula: y/x
Substituted Slope Formula: (95 - 80)/(10 - 6)
Simplified Substituted Slope Formula: 15/4 OR 3.75
Hope this helps!!
the number changes by the degree so you need to multiply it.
3*4=12
2x*4=8x
So,answer is 8x+12
<u>ANSWER</u>
The vertex form is 
<u>EXPLANATION</u>
We use completing squares
We factor -4 out of the first two terms
We add and subtract 
, that is coming from, 
.
The expression in the first parenthesis is now a perfect square.
The function is now in the form,
, where 
is the vertex
Hence the vertex is
X² + 4x - 8 = 5
This is a simple quadratic equation. Let's move everything to the left side to start:
x² + 4x - 8 - 5 = 5 - 5
Now we have:
x² + 4x - 13 = 0
In a quadratic equation, x =
Therefore, we plug in a = 1, b = 4, and c = -13, and we find that x = -2 - sqrt{17} OR -2 + sqrt{17}.
