Answer:

Step-by-step explanation:

The discriminant comes from the quadratic formula. We use the discriminant to determine, before factoring, what types of solutions we can expect when we do factor. In the quadratic formula, the discriminant is under a square root sign. If the number under a square root sign is negative (meaning the discriminant is negative), we will not have real number solutions because you can't have a negative number under a square root. So a is your choice.

What is the equation of a line that passes through the points (0,5) and (4,8)? Write your answer in slope-intercept form.
7nadin3 [17]

Answer:

y=3/4x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-5)/(4-0)

m=3/4

y-y1=m(x-x1)

y-5=3/4(x-0)

y-5=3/4(x)

y-5=3/4x

y=3/4x+5

Can someone please solve
pentagon [3]

Answer:

78

Step-by-step explanation:

Evaluate 6 (2 x^2 - 5) where x = -3:

6 (2 x^2 - 5) = 6 (2×(-3)^2 - 5)

Hint: | Evaluate (-3)^2.

(-3)^2 = 9:

6 (2×9 - 5)

Hint: | Multiply 2 and 9 together.

2×9 = 18:

6 (18 - 5)

Hint: | Subtract 5 from 18.

| 1 | 8

- | | 5

| 1 | 3:

6×13

Hint: | Multiply 6 and 13 together.

6×13 = 78:
