Answer:
The axis of symmetry is x = 6
Step-by-step explanation:
To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.
x + 9 = 0
x = -9
x - 21 = 0
x = 21
Now take the average of these two numbers.
(-9 + 21)/2
12/2
6

Answer:
A, D, and E
Step-by-step explanation:
80% off 22 is 17.6
A- 80 ? 100=0.8 x 22= 17.6
D- 0.8 x 22= 17.6
E- 4/5=0.8 x 22= 17.6
Step-by-step explanation:
To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape. subtract basic figure volumes NOT belonging to the composite figure.
