Answer:
2
Step-by-step explanation:
First, we are going to rewrite it as a parabola equation.
Rewrite.

Divide by 8.

Factor out coefficient.

Then, we are going to convert x into square form.

Convert the whole expression into square form.

Simplify.

Subtract 6 from both sides.

Divide by coefficient.

Rewrite in standard form.
The radius of the circle will be -2. Also, no matter what the sign says, the radius has to always be positive.
Have a nice day! :)
Answer:
Y-intercept (0,-20)
Answer:
y = 3/2x + 6
Step-by-step explanation:
y = 3/2x - 4
y-intercept through point (-2, 3):
3 = 3/2(-2) + b
3 = -3 + b
b = 6
Equation of line:
y = mx + b
y = 3/2x + 6
**Parallel line share the same slope, in this case 3/2.
For the first number you can choose from 8, for the second number only 7, for the third number only 6. So the number of combinations is 8x7x6=336
