Answer:
2) is addition property
3) is multiplication property
Step-by-step explanation:
Using the cosine function:
Solve for b:

Answer:
f(7) = -113
Step-by-step explanation:
Hello!
Substitute 7 for x in the equation.
<h3>Evaluate</h3>
- f(x) = -4x² + 10x + 13
- f(7) = -4(7)² + 10(7) + 13
- f(7) = -4(49) + 70 + 13
- f(7) = -196 + 70 + 13
- f(7) = -113
f(7) is -113.
This is pretty simple once you get used to this
First set it equal to the original and the negative one
(>_) is the bigger and equal to part
4x+5>_45 or 4x+5>_-45
Then solve for x for both
4x>_40. 4x>_-50
X>_10 X>_-25/2
Figure B is the answer!
The formula for the Pythagorean theorem is
A^2+B^2=C^2
In figure B the units are squared. Making it your answer.
