65% of 39 is 60 the answer is 60
Simplify brackets
2/5(x - 4) = 2x
Simplify 2/5(x - 4) to 2(x - 4)/5
2(x - 4)/5 = 2x
Multiply both sides by 5
2(x - 4) = 10x
Divide both sides by 2
x - 4 = 5x
Subtract x from both sides
-4 = 5x - x
Simplify 5x - x to 4x
-4 = 4x
Divide both sides by 4
-1 = x
Switch sides
<u>x = -1</u>
Answer:
Step-by-step explanation:
The answer for this is
See the red line in the graph which says f(X)
See the blue line in the graph which says g(X)
So these are the variables which come under the example of exponential functions
And the answer is option B. Both graphs are exponential functions.
Answer: x = 12 and y = -8
Explanation:
x + y = 4
4x + 3y = 24
———————
-3(x + y = 4)
4x + 3y = 24
———————-
-3x - 3y = -12
4x + 3y = 24
———————
x = 12
If x = 12
x + y = 4
12 + y = 4
y = -8
Answer:
Reference angles are always acute.
We can find the reference angle with the "formula"
π

θ
, where
θ
is our given angle.
We can plug
