In order to invert a function, switch y and x in the definition, and solve for y again:
Solving for y, we have
Answer:
I got 8, but I'm not sure.
Step-by-step explanation:
So I first did -6 + 5, and I got -1 as an answer. Then I did -1 plus 9 because both sides need to be equal. I wrote that x = 8 but that wasn't an option. I'm not sure if this was helpful and I'm really sorry if it's not.
Answer:
Distributive property

Answer:
x = 121
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 7, thus
sum = 180° × 5 = 900°
Sum the given angles and equate to 900
x + 125 + 119 + 117 + 145 + 133 + 140 = 900, that is
x + 779 = 900 ( subtract 779 from both sides )
x = 121
