Answer:
x=1
Step-by-step explanation:
-4-2(3-x)=-2(x+3)
Expand parentheses:
-4-6+2x=-2x-6
Add 2x+6 to both sides:
4x-4=0
Add 4 to both sides:
4x=4
Divide both sides by 4:
x=1
Hope this helps!

Answer: 9.9
Step-by-step explanation:
SINE RULE:
7/sin(31) = q / sin(47)
Therefore q = 7 / sin(31) * sin(47)
which equals: 9.9 to the nearest tenth.
Answer:
w = 25
Step-by-step explanation:
- 45+30 = 100 - w
- 75 = 100 - w
- w = 100 - 75
- w = 25
Answer:
x, y, 4, 0
Step-by-step explanation:
To determine the inverse of the given function change f(x) to y switch <u><em>x</em></u> and y and solve for <u><em>y</em></u>.
f(x) = sqrt(x - 4)
y = sqrt(x - 4)
x = sqrt(y - 4)
x^2 = y - 4
x^2 + 4 = y
y = x^2 + 4
The domain of the inverse is the same as the range of the original function.
inverse f(x) = x^2 + 4
x^2 + 4 >= 4
x^2 >= 0
x >= 0
The resulting function can be written as inverse f(x) = x^4 + <u><em>4</em></u>, where x >= <u><em>0</em></u>.
