Answer:

4b³ + 11b² - 6b + 13

Step-by-step explanation:

Subtract like terms.

6b³ - 2b³ = 4b³

3b² - (-8b²) = 3b² + 8b² = 11b²

0 - 6b = -6b

8 - (-5) = 13

All together, the difference is 4b³ + 11b² - 6b + 13.

(-3,0),(5,-2) find the slope
Mashcka [7]

Answer:

-4

Step-by-step explanation:

Point slope form: y - y = m (x - x)

5 - (-3) = m (-2 - 0)

5 + 3 = m (-2)

8 = m (-2)

m = 8/(-2)

m=4

A certain function is defined as "multiply the input by -3/4,then add 2 I need the function rule asap
Olegator [25]
Hi there!

The answer is:
y = - \frac{3}{4} x + 2

Let the input be represented by X. We can see we have to multiply it by -3/4, so we get -3/4X. To find our outcome (which is represented by y), we only have to add 2 to the function.
y (outcome) = - 3/4x (income) + 2

y = - \frac{3}{4} x + 2

What is the equation of a line that is parallel to −3x+4y=4 and passes through the point (4, 0) ?
Degger [83]
First, change the given equation to slope-intercept form:

4y = 3x + 4
y = (3/4)x + 1

Because the line we are trying to write the equation for is parallel to the above line, the new line must have the same slope (3/4).

We can then substitute (4, 0) to find the y-intercept (b):

0 = (3/4) * 4 + b
0 = 3 + b
-3 = b

Our y-intercept is -3

We can now write the whole equation:

y = (3/4)x - 3

Your final answer is y = (3/4)x - 3

Hope this helps!! Let me know if you have ANY questions.
