Answer:
18
Step-by-step explanation:
Given
x - 1 = 2 ( add 1 to both sides )
x = 3
Then
2x² = 2(3)² = 2 × 9 = 18
Answer:
-$43.67
Step-by-step explanation:
your balance was negative $12.71 then you still took $30.96 for the groceries so the equation suppose be
-12.71 -30.96

Answer:
No amplitude
Period is pi
Step-by-step explanation:
Answer:
y = -19
Step-by-step explanation:
The equation has a negative slope (-3). This means the y value decreases as x increases. Since the maximum value for x is 5 (≤5), we know that the value produced when x = -5 will result in the smallest value of y.
In this case,
y = -3x - 4
y = -3(5) - 4
y = -19
See attached graph.
So add 6.5 to both sides. 1/2x > 18.5.
Multiply both sides by 2.
So it's x > 37.
