Is (2, 2) a solution of y < 4x – 6?

Roman55 [17]

Answer:

Step-by-step explanation:

To see if (2,2) is a solution, substitute them into the inequality and see if it is true.

2 is our x value, and 2 is also our y value

y < 4x – 6

2< 4(2)– 6

2 < 8 – 6

2 < 2

This statement is false. 2 is not less than 2, so (2,2) is not a solution to this equation.

yanalaym [24]

Answer:

Option C.

Step-by-step explanation:

A dashed straight line has a negative slope and goes through (0, 2) and (4, 0).

The given inequality is

$y$

We need find the point which is a solution to the given linear inequality.

Check the given inequality for point (2, 3).

$3$

This statement is false. Option 1 is incorrect.

Check the given inequality for point (2, 1).

$1$

This statement is false. Option 2 is incorrect.

Check the given inequality for point (3, -2).

$-2$

This statement is false. Option 3 is correct.

Check the given inequality for point (-1,3).

$3$

This statement is false. Option 4 is incorrect.

Therefore, the correct option is C.

Use the discriminant to determine the number of solutions and types of solutions for the quadratic equation, below. Then answer

Setler79 [48]

Answer:

A. Discriminant = 116

B. Number of solutions for the quadratic equation = 2

C. Type of solutions (circle one):Imaginary

D. Type of solutions (circle one):irrational

Step-by-step explanation:

The given quadratic equation is

${x}^{2} + 8x = 13$

We rewrite in standard form to get;

${x}^{2} + 8x - 13 = 0$

The discriminant is

$D = {b}^{2} - 4ac$

where a=1, b=8, c=-13

We substitute to get:

$D = {8}^{2} - 4 \times 1 \times - 13$

$D = 64 + 52$

$D = 116$

Since the discriminant is great than zero, we have two distinct real roots

The 200 meter race times at a state track meet are normally distributed with a mean of 13.56 seconds and a standard deviation of

BaLLatris [955]

Answer:

A. 0.4880

Step-by-step explanation:

First, find the z-score:

z = (x − μ) / σ

z = (13.5 − 13.56) / 2.24

z = -0.03

Using a z-score table:

P(z < -0.03) = 0.4880
