Answer:

A: (-7, 4)

B: (-6, -4)

C: (0, -3)

D: (2, 0)

Step-by-step explanation:

The first number in an ordered pair is the x point, so which number the point aligns with on the horizontal line.

The second number in an ordered pair is the y point, so which number the point aligns with on the vertical line.

If you look at point B you can see that it is directly below the -6 on the horizontal line and directly left of the -4 on the vertical line.

This means that point B is at (-6, 4)

A is your answer. Parallel lines never intersect. They both run the same direction, the same distance from each other.

a quadratic equation has a discriminant of 12. which could be the equation? a.0 = –x2 8x 2 b.0 = 2x2 6x 3 c.0 = –x2 4x 1 d.0 = 4

Norma-Jean [14]

Answer:

Option b which is $2x^2+6x+3=0$

Step-by-step explanation:

We have been given the discriminant 12

We have to choose the equation which will satisfy the given discriminant.

We will consider all the given equation one by one

First we will take option a which is $-x^2+8x+2=0$

Discriminant from the equation we will find by the formula

$D=b^2-4ac$

Here, a=-1,b=8 and c=2 on substituting the values we will get

$D=8^2-4(-1)(2)=72$

Hence, option a is incorrect.

Now, we will consider option b which is $2x^2+6x+3=0$

Here, a=2,b=6 and c=3 on substituting the values we get

$D=(6)^2-4(2)(3)=12$

Hence, option b is correct

Therefore, option b is the required answer.

Complete 5^9/5^3=5^a

Goryan [66]

Answer:

6=a

Step-by-step explanation:

5^9/5^3=5^a

We know that b^c = b^d = b^(c-d)

5^9/5^3=5^a

5^(9-3) = 5^a

5^6 = 5^a

The bases are the same so the exponents are the same

6=a
