Answer:
a. Negative discriminant: above
b. Positive discriminant: below
c. Discriminant is zero: on
Step-by-step explanation:
If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis
If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis
If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis
Answer:
32
Step-by-step explanation:
39 = 4(x + 5) + 2x + 1
39 = 4x + 20 + 2x + 1
39 = 6x + 21
18 = 6x
x = 3
MN = 4(x + 5)
MN = 4(3 + 5)
MN = 4(8)
MN = 32
hope this helped!
Answer:
f(x) = -4x-1
f(7) = -(4)(7)-1
f(7) = -29
g(x) = 4x^2 - x
g(-4) = 4(-4)^2 - (-4)
g(-4) = 4(16) + 4
g(-4) = 64 + 4
g(-4) = 68
Let me know if this helps!
400 because if you add 324.5+75.5 it equals 400
Answer is D. y = 1/2x + 3
Explanation
you are looking for “least steep” on the graph, so you are looking for the least amount of slope. Slope is the number next to x in the slope intercept y=mx+b.
1/2 on a graph would be 1 up and 2 to the right
The other three options would be 1 up 1 over, 2 up 1 over, 3 up 1 over, all having a steeper slope.
