Answer:
B 9, -9
Step-by-step explanation:
x^2 - 81 = 0
Add 81 to each side
x^2 = 81
Take the square root of each side
sqrt(x^2) = sqrt(81)
x = ±9
Simplify them until they can be simplified no more, then compare both sides.
Answer:
15/30:2/30
15/30=2/30x
divide by 15/30
7.5 is x
Step-by-step explanation:
Larger because I want the points and you are going to get an F
To find the ordered pair, we simply set the x value equal to 6.
We already know the first coordinate will be 6.
f(6) = 3(6) - 4
f(6) = 18 - 4
f(6) = 14
<h3><u>The y value is 14, and so our coordinate pair is (6, 14)</u></h3>
