Answer: false.

Step-by-step explanation: the equation is as follows:

-3 + 7 = 7 - 3, which = 5

-3 times 5 = -15, making the statement false.

Can you help me figure out the slope of this line? please and thx ASAP.

The rise is the vertical distance between the two points, which is the difference between their y-coordinates. That makes the rise y2 − y1. The run between these two points is the difference in the x-coordinates, or x2 − x1.

Divide (-3x^2 - 9x) ÷ (x + 3) please explain/show work! <33

Stolb23 [73]

Step-by-step explanation:

 $( - 3 {x}^{2} - 9x) \div (x + 3)$ 

This is the original equation so you will open the brackets.

 $- 3 {x}^{2} - 9x \div x + 3$ 

The x will cross the division sign making it times x.

 $3 {x}^{2} - 9x \times x = 3$ 

So you will proceed to multiply the 9x by x making it;

 $3 {x}^{2} - 9 {x}^{2} = 3$ 

So you will subtract 9x² from 3x² which won't be possible so it will be negative.

 $- 6 {x}^{2} = 3$ 

Then you will square root both sides making it;

 $- \sqrt{6 {x}^{2} } = \sqrt{3}$ 

So the ² will cancel the √ leaving 

-6x=√3

-6x=1.73(Divide both sides by -6)

x=0.288

That's the final answer.
