Answer:
y=-3
y=6
y=15
y=24
y=32
Step-by-step explanation:
Replace x with the numbers
Remember PEMDAS(order of operations)
1) y=-1*9+6
y=-3
2) y=0*9+6
y=6
3) y=1*9+6
y=15
4) y=2*9+6
y=24
5) y= 3*9+6
y=32
Answer:
$132.63
Step-by-step explanation:
$49.13 - ($32.50 × 2)
$49.13 - $65 = $-15.87
$-15.87 + ($74.25 × 2)
$-15.87 + $148.50
=$132.63
Answer:
f(x) = - 2 (x + 2)² + 6
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 2, 6), thus
y = a(x - (- 2))² + 6, that is
y = a(x + 2)² + 6
To find a substitute the point (0, - 2) into the equation
- 2 = a(0 + 2)² + 6 ( subtract 6 from both sides )
- 8 = 4a ( divide both sides by 4 )
- 2 = a
f(x) = - 2(x + 2)² + 6 ← in vertex form
Answer:
D) (9 , 5)
Step-by-step explanation:
y = x - 4
Substitute x = 9 value in the equation
y = 9 - 4 = 5
We got the y value as 5
So, (9,5) is the pair generated by the equation
