Answer:
B
Step-by-step explanation:
3x - 2y = 8 → (1)
x + y = 6 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate y
2x + 2y = 12 → (3)
Add (1) and (3) term by term to eliminate y
(3x + 2x) + (- 2y + 2y) = (8 + 12) , that is
5x + 0 = 20
5x = 20 → B
It’s gotta be C since the “b” term in the equation shows the y intercept; -3 is less than the rest. Don’t listen to the other guy commenting here!

The discriminant of the function is 120, and the function has 2 different x-intercepts
<h3>How to determine the discriminant?</h3>
The function is given as:
f(x) = -7x^2 + 8x + 2
The discriminant (d) is calculated using:
D =b^2 - 4ac
So, we have:
D = 8^2 - 4 * (-7) * 2
Evaluate
D = 120
Because the value of D is greater than 0, then the function has 2 different x-intercepts
