Answer:
x1 = -4.872983346
x2 = 2.872983346
Step-by-step explanation:
<u>Given:</u>
x^2+2x+7=21
<u>Subtract 21 on both sides to get the right side equal to 0:</u>
x^2+2x-14=0
<u>Use the quadratic formula:</u>
x1 = -4.872983346
x2 = 2.872983346
Answer: I think it’s B. Output values
Well, to find the answer to this problem you have to change the -15 to a positive (+15) and add the two numbers together. And, 15 + 68 = +83 degrees.
So, your answer is: A. +83 degrees.
It's really easy because all your doing is changing the -15 to a positive 15 and adding the two numbers together to get your answer.
Hope I helped!

Answer:
The slope is -4/5
The y intercept is (0,7)
Step-by-step explanation:
f(x) = 7 -4/5x
Rewriting
y = -4/5x +7
This is in slope intercept form
y = mx+b where m is the slope and x is the y intercept
The slope is -4/5
The y intercept is (0,7)
