The answer is C) z - 2 = 5.
z - 2 = 5
Add 2 to both sides of the equal sign.
z - 2 + 2 = 5 + 2
z = 7.
Therefore, the solution is 7.
Hope this helps!
Answer:
x = 7
Step-by-step explanation:
Let
x = the unknown number
double it :
2x
add 11:
2x + 11
I get 25:
The equation is
2x + 11 = 25
2x = 25 - 12
2x = 14
Divide both sides by 2
x = 14/2
x = 7
The question is an illustration of a number line, and the point located at -8.65 is B
<h3>How to determine the point?</h3>
From the complete question, we have the following highlight
Point B is between -8 and -9, and point B is closer to -9 than -8
No other point is between -8 and -9
So, we can conclude that the point located at -8.65 is point B

Answer:
Step-by-step explanation:
We are asked to express cos^ 3 x in terms of powers of trigonometric functions not greater than 1
cos ^ 3 x is equal to cos x * cos^2 x.
<span>cos^2 x = 1 - sin^2 x.
</span>sin^2 x = (1 - cos 2x) /2
the answer is cos ^ 3 x = cos x * (1 - <span> (1 - cos 2x) /2 )</span>
