Answer:

B

Step-by-step explanation:

In a linear function, the <u>rate of change</u> (slope) is constant.

Therefore, as the x-value increases or decreases by a constant, the y-values should also increase or decrease by a constant.

<u>A = {(0, -1), (3, 3), (6, 6), (9, 9)}</u>

  • The x-values increase by 3 each time.
  • The y-values increase by 4, 3, and 3.

Therefore, this is <u>not</u> a linear function as the increase in y-values is not constant compared to a constant increase in x-values.

<u>B = {(-1, -6), (1, -2), (3, 2), (5, 6)}</u>

  • The x-values increase by 2 each time.
  • The y-values increase by 4 each time.

Therefore, this is a linear function as the increase in x-values and y-values is constant.

<u>C = {(-6, 6), (-4, 3), (2, -6), (4, -8)}</u>

  • The x-values increase by 2, 6, and 2.
  • The y-values increase by -3, -9, and -2.

As the ratio of increases in x-values and y-values is not the same, this is <u>not</u> a linear function.

<u>D = {(-2, 9), (1, 3), (3, -3), (6, -9)}</u>

  • The x-values increase by 3, 2, and 3.
  • The y-values increase by -6 each time.

Therefore, this is <u>not</u> a linear function as the increase in x-values is not constant compared to a constant increase in y-values.

Which equation represents the model shown below
Alona [7]

Answer:

-4x - 3 = -8

Step-by-step explanation:

On our left, we have -x in 4 places = 4(-x) = -4x

And on the left, we also have -1 in 3 places = 3(-1) = -3

Altogether in our left, we have: -4x +(-3)

That is: -4x - 3

On our right, we have -1 in 8 places, which is 8(-1) = -8

Therefore, the equation that represents the model would be:

-4x - 3 = -8

On the number line, a bug P is moving in the positive direction from the point 0, and a bug N is moving in the negative directio
Hatshy [7]
They are 150 units apart.

Since P travels in a positive direction 8 units in 4 seconds, this means that P's speed is 2 units/sec.

Since N travels in a negative direction 12 units in 4 seconds, this means that N's speed is -3 units/sec.

After 30 seconds, P will have traveled 2(30) = 60 units.
After 30 seconds, N will have traveled -3(30) = -90 units.

60--90 = 150.

What is the value of x? sin(x 37)°=cos(2x 8)° enter your answer in the box. x =
Assoli18 [71]
Applying the trig formula: sin a = cos (90 - a)
cos (2x + 8) = sin (x + 37) = cos (90 - x - 37) = cos (53 - x)
Property of the cosine function -->

)

a. 2x + 8 = 53 - x
3x = 45
x

b. 2x + 8 = - 53 + x
x

Check by calculator.
x = 15 --> sin (x + 37) = sin 52 = 0.788
cos (2x + 8) = cos (38) = 0.788. Proved
x = - 61 --> sin (x + 37) = sin (- 24) = - sin 24 = - 0.407
cos (2x + 8) = cos (-122 + 8) = cos (- 114) = - 0.407. Proved
