Answer:
(b) 20 1/4
Step-by-step explanation:
9(-3)^2(2^-2) = 9(9)(1/4) = 81/4 = 20 1/4
Answer:
The answer is 80°
Step-by-step explanation:
pls give brainliest!
all angles = 360°
100+100+80=280°
360°-280°=80°
Answer:
y+6=9(x+4)
Step-by-step explanation:
point slope form is y-y1=m(X-x1)
y1 is -6
x1 is -4
And the slope or m is 9 so we can fill it in
y-(-6)=9(x-(-4))
y+6=9(x+4)
we can fill the equation out to see if it’s true
-6+6=9(-4+4)
0=9(0)
0=0
It is true

Explanation:</h2>
Hello! here we need to match the statements on the left-hand side to the reasons on the right-hand-side.
So this is as follows:
Statements: Reasons:
Segment Addition Postulate 
Substitute the given values 
Simplify 
Subtract 5x from both sides 
Divide both sides by 2 
Simplify 
Substitute 8 for x 
Simplify 
So what we did here is to find the measure of segment AC by finding the x-value first. In other words, we have proven that AC = 56 by following logical arguments organized in an structured manner.
