Answer: 12
Step-by-step explanation:
2x + 8 = 3x - 4
In order to solve for x, we must isolate x. We can do this by moving all of the numbers with "x" in it to the left side of the equal side, and move everything else to the right of it!
Let's start off by subtracting 8 from both sides. Remember : what you do to one side, you must do it to the other.
2x + 8 - 8 = 3x - 4 - 8
Simplify!
2x = 3x - 12
Now, let's subtract 3x from both sides.
2x - 3x = 3x - 12 - 3x
Simplify!
-x = -12
Divide both sides by -1.
-x ÷ -1 = -12 ÷ -1
Simplify.
x = 12

Answer:
The inverse of the function h(x) is
.
Step-by-step explanation:
The given function is

Replace h(x) by y.

Interchange x and y.

Subtract 4 from both sides to isolate variable y,

Multiply both sides by 2.

Divide both sides by 5.

Replace y by h⁻¹(x).

Therefore the inverse of the function h(x) is
.
<u>Answer:</u>
Lin: 25 × 8,2 =<em> 205 meters</em>
Elena: 250 ÷ 28 = <em>8,9 meters per second</em>
Diego: 32 × (-8,1) = <em>-250,2 meters</em>
Andre: -258 ÷ 25 = <em>-10,32 meters per second </em>
Hello!
173 + 32 = 205
5 * 205 = 1025
