F(x) = 3x² - 1
f(-2) = 3(-2)² - 1
f(-2) = 3(4) - 1
f(-2) = 12 - 1
f(-2) = 11
f(x) = x < 1
f(-2) = -2 < 1
f(x) = x + 2
f(-2) = -2 + 2
f(-2) = 0
f(x) = x > 1
f(-2) = -2 > 1
f(-2) = -2 < 1

Answer:
x = 15
Step-by-step explanation:
75 + 10x = 225

10x = 150
divide both sides by 10
x = 15
Answer:
<em>There are </em><em>82</em><em> number of seats in the 18th row.</em>
Step-by-step explanation:
Given that, there are 14 seats in the first row, 18 seats in the second row, 22 seats in the third row, and so on.
i.e (14, 18, 22, ........so on)
This series is in Arithmetic Progression.
Here,
a = initial term = 14
d = common difference = 4
As we have to calculate number of seats in 18th row, so we have find n₁₈
We know that,
Putting the values,
Answer:
The overall image would be 4 units to the right and 3 units down on the coordinate plane.
Step-by-step explanation:
(x+4,y-3) means that the x value of each coordinate gets increased by 4 and the y value of each coordinate gets decreased by 3. The overall image would be 4 units to the right and 3 units down on the coordinate plane.
