Answer:

Step-by-step explanation:
We have:

And we want to solve for y when x is -9.
So, substitute -9 for x and evaluate:

Hence, when x is -9, y is -13.
Answer: The root of this function would be (7,0)
Answer:
-6
Step-by-step explanation:
Answer:
27.3 yards
Step-by-step explanation:
Since this triangle is a right triangle, this can be solved using the equation:
a^2 + b^2 = c^2
c^2 is the side opposite to the right angle (37)
So, you need to change the equation to where it is set equal to b^2.
Subtract a^2 on both sides.
b^2 = c^2 - a^2
Now, plug in the numbers you have.
b^2 = 37^2 - 25^2
Simplify.
b^2 = 1369 - 625
b^2 = 744
Now, to find b, take the square root of 744.
√744 = 27.3
