If you can please help me

finlep [7]

Answer/Step-by-step explanation:

1. -14

2. 3

3. -3

4. 10

5. -8

1. 4 x -3 = -12 - 2 = 14

2. -3 x 2 = -6 + 9 = 3

3. 8 divided by 4 = 2 - 5 = -3

4. 3/2 = 1.5 x 2 = 3 + 7 = 10

5. -9/3 = -3 - 5 = -8

Need help with both of them pleaseee

defon

For problem 12 you would do 44.8 times 5 and that would give you 224 miles.

Problem 13: In the first race he drove at an average speed of 149 miles per hour. I got this by dividing 2.5 by 372.5. In the second race he drove 144 miles per hour. I determined this by dividing 3.2 by 460.8. Therefore, in his first race he drove the fastest average speed.

I hope this helps!

Are the graphs of the lines in the pair parallel? Explain.<br><br> y = 2/3x– 17<br> 4x – 6y = –6

goldenfox [79]

Answer:

Yes, they are parallel.

Step-by-step explanation:

Parallel lines have the same slope. We must find the slopes of the two lines.

When the equation of a line is written in the slope-intercept form,

y = mx + b,

the slope is m.

The first line has equation

$y = \dfrac{2}{3}x - 17$

It is already written in the slope-intercept form. Comparing y = 2/3x - 17 with y = mx + b, you see that m = 2/3. The slope of the first line is 2/3.

Now we solve the second equation for y to obtain the slope-intercept form of that equation.

4x - 6y = -6

Subtract 4x from both sides.

-6y = -4x - 6

Divide both sides by -6.

$\dfrac{-6}{-6}y = \dfrac{-4}{-6}x + \dfrac{-6}{-6}$

$y = \dfrac{2}{3}x + 1$

We now compare this form of the second equation with y = mx + b, and we see that m = 2/3.

Both equations have the same slope, 2/3, so the lines are parallel.
