Answer:

A. if the discriminant is zero there is real solution

B. if the discriminant is negative there are 0 real solutions

C. if the discriminant is positive there are 2 real solutions​

Step-by-step explanation:

B² - 4AC is the discriminant

If B²-4AC < 0, no real roots

If B2-4AC = 0, roots are real and repeated

If B²-4AC > 0, roots are real and distinct

Answer:

A, B, and C

Step-by-step explanation:

The discriminant is denoted by b^2 - 4ac, and it can give us information about the roots of the quadratic equation.

It tells us that if:

- b^2 - 4ac < 0 , then there are 0 real solutions; they're all imaginary (involving the letter i, which is the square root of -1)

- b^2 - 4ac = 0 , then there is 1 real solution; this 1 solution has a multiplicity of 2 because the roots of the quadratic are the same number

- b^2 - 4ac > 0 , then there are 2 real solutions; there are no imaginary solutions

Looking at the possible choices, we see that all of A (A, I'm assuming you meant to write "if the discriminant is zero there is one real solution"), B, and C reflect the above properties.

Thus, they're all right.

I WILL MARK AS BRAINLIEST! Solve for Y
zzz [600]

Answer:

See below.

Step-by-step explanation:

Substitute the value for the variable and solve.

a.)

⇒ y = -5(3) + 17

⇒ y = -15 + 17

⇒ y = 2

b.)

⇒ y = 3(3) - 22

⇒ y = 9 - 22

⇒ y = -13

c.)

⇒ y = 2(3) - 25

⇒ y = 6 - 25

⇒ y = -19

d.)

⇒ y = 6(3) - 39

⇒ y = 18 - 39

⇒ y = -21
