Answer:
Step-by-step explanation:
The angles are complimentary, so they add to 90
6x + 3 + 7x + 9 = 90 Combine like terms
13x + 12 = 90 Subtract 12 from both sides
13x = 90 - 12 Combine
13x = 78 Divide both sides by 13
x = 6
<A = 6x + 3
<A = 6*6 + 3
<A = 36 + 3
<A = 39
Answer:
y - 4 = 0
Step-by-step explanation:
They give you the y coordinate, 4, and the x coordinate as 0.
Put 4 in as y.
4 - 4 = 0. That means x = 0 and that is right.
To make sure it has a slope of zero, subtract 4 on both sides.
You get : y = 4. This means that the line will be straight and it will have a slope of zero.
Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
f(x) = x - 2
g(x) = x²
In order to find (fog)(-1) we must first find (fog)(x)
To find (fog)(x) substitute the g(x) into f(x) that's for every x in f (x) replace it with
g (x).
That's
(fog)(x) = x² - 2
To find (fog)(-1) substitute the value of x that's - 1 into (fog)(x)
We have
(fog)(-1) = (-1)² - 2 = 1 - 2 = - 1

Answer:
Step-by-step explanation:
<u>Given</u>
<u>Solving in steps</u>
- 1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)
- 2. ⇒ z = - (2.5 - 0.72)
- 3. ⇒ z = - 1.78
The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72
