The answer is B. -3
hope this helps!
Answer:
g ∈ ∅
Step-by-step explanation:
Expand the expression
30 g + 12 = 30
Cancel out the 30g on both sides
12 = 0
Decide whether the statement is true or false
g ∈ ∅
The inverse of function f(x) = 9x+7 is f-1(x) = x/9 - 7/9
<h3>How to determine the inverse of the function?</h3>
The function is given as:
f(x) = 9x + 7
Express f(x) as y
y = 9x + 7
Swap the positions of x and y in the above equation
x = 9y + 7
Subtract 7 from both sides
9y = x - 7
Divide through by 9
y = x/9 - 7/9
Express as an inverse function
f-1(x) = x/9 - 7/9
Hence, the inverse of function f(x) = 9x+7 is f-1(x) = x/9 - 7/9

x ≥ 4 which means that x must be greater than or equal to 4.
<h3>What is inequality?</h3>
An Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Given inequality as :
⇒ 2x - 2 ≥ 6
Divided by 2 both sides of the inequality,
⇒ x - 1 ≥ 3
Add the 1 on both sides of the inequality,
⇒ x - 1 + 1 ≥ 3 + 1
⇒ x ≥ 4 or
⇒ x ∈ [4, ∞ )
So, the solution of 2x - 2 ≥ 6 is x ≥ 4
Therefore, x must be greater than or equal to 4.
