Answer:
16
Step-by-step explanation:
Use the order PEMDAS
So, parenthesises first.
(2 + 2)
= 4
Then divide.
8/2
= 4
Then multiply.
4(4)
= 16
Answer:
x=-7
Step-by-step explanation:

You would set the problem into slope-interslope form : y = mx + b.
Slope (m) = rate of change b = y-intercept
Therefore, your in the above:
m = 3
b = 0
The constant proportionality (slope) is 3 and the y-intercept is 0.
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = - 2x² + 4x - 2
To find the y- intercept set x = 0
f(0) = 0 + 0 - 2 = - 2 ← y- intercept
The equation of the axis of symmetry is of the form x = c
where c is the value of the x- coordinate the line goes through.
Given the equation in standard form
with a = - 2, b = 4 then the axis of symmetry is
x = -
= -
= 1
Equation of axis of symmetry is x = 1
