Answer:
see below
Step-by-step explanation:
A discriminant value of zero means there is exactly one x-intercept. The graph below has that characteristic.
_____
<em>Comment on discriminant</em>
discriminant > 0, two (2) x-intercepts (first 2 graphs)
discriminant < 0, no (0) x-intercepts (third graph)
Answer:
This answer is not possible.
Step-by-step explanation:
If you did every combination none of them would be equal to 30, so using these numbers you cannot make this answer true
Y=2x + 6. ( because 2x is 2 quarters a day and you started with 6
X + y = 20 Substitute
x by 2 y - 4 in x + y = 20 to obtain 2 y •
4 + y = 20 Solve for y to find y = 8 and
x = 2y - 4 = 12
