Answer:

Step-by-step explanation:

A positive correlation is a relationship between two variables that move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.

Solve for x: 4x > -28

AnnZ [28]

Answer:

x> -7

Step-by-step explanation:

Divide by 4

4x/4 >-28/4

x > - 7

The arrow does not change direction unless you are dividing by a minus. Then the arrow goes in the opposite direction to the way it is currently going.

What is the slope of a line parallel to the line whose equation is 3x – 3y = -45.

Karolina [17]

Answer:

One

Step-by-step explanation:

A parallel line has the same slope of the original graph. Because of this, all we need to do is put the equation you gave into slop-intercept form, or:

y = mx + b

Don't forget that m is the slope, and b is the y-intercept!

3x - 3y = 45

-3y = -3x + 45

y = x + 15

Compare this to the equation of the slope-intercept form and look for m:

y = mx + b

There's nothing in front of the variable! No worries, that's the same thing as saying 1x.

But mathematicians are a little lazy (lol) and they don't want to mistake the number 1 for the lowercase letter L or a capital i. Because of that, they made 1x equal x.

Long story short, the slope for the equation (3x – 3y = -45) is one. And because parallel lines have the same slope as their original counterparts, the slope is one as well!

I recommend trying a few other problems like these. You'll end up using them a lot in the future!

Good luck and keep studying!

Find the y intercept!

Irina-Kira [14]

Answer:

-23

Step-by-step explanation:

We note that as x increases by 36 from -72 to 36, y decreases by 24 from 25 to 1.

Increasing x from -36 by another 36 to zero will correspond to a decrease in y by another 24 from 1 to -23.

The y-intercept is -23.

_____

You could go to the trouble to use these observations to compute the slope as -24/36 = -2/3. Then you could pick one of the points and write the equation in point-slope form as ...

y = -2/3(x +36) +1 . . . point-slope form with m=-2/3, (h, k) = (-36, 1)

y = -2/3x -24 +1 . . . . . eliminate parentheses

y = -2/3x -23 . . . . . . . y-intercept is -23
