Hello from MrBillDoesMath!


Answer:    

       Domain restriction:  -3  <= x <= 0

       Range restriction:    -4 <= y <= 0

Discussion

These numbers came directly from the graph. I am assuming the endpoints such as x = -3 are included in the domain.

Please help!!!!<br> Write the equation of the given line in slope-intercept form.
Tpy6a [65]
<h3>Answer:</h3>

y = -3x +2

<h3>Step-by-step explanation:</h3>

The y-intercept is at +2, so that is the value of the added constant (b).

The line goes down 3 units for each unit to the right, so the slope (m) is ...

... m = ∆y/∆x = -3/1 = -3

Then in the form ...

... y = mx + b

with m=-3 and b=2, your line's equation is ...

... y = -3x +2

Simplify 3(4x + 6) - 9x.<br><br> -15x + 18<br> 3x + 18<br> 3x + 6<br> 12x + 18 - 9x
Readme [11.4K]
3(4x + 6) - 9x

Apply the Distributive Property:
3 (4x) + 3 * 6 - 9x

Multiply by 4 by 3 to get 12:
12x + 3 * 6 -9x

Multiply 3 by 6 to get 18:
12x + 18 - 9x

Subtract 9x from 12x to get 3x:
3x + 18

Your answer is the second option!
