Answer:

C. -4<x<=0

Step-by-step explanation:

-4 has an open dot, so that means that it is not going have an "or equal to" sign, it is going to the right, so x must be greater than -4.

0 is going to the left so x must be "less than or equal to" 0 because it has a closed dot.

Help please!!! thanks

Answer:

Step-by-step explanation:

first we can simplify by dividing by r

$\frac{9 {r}^{2} }{r} = \frac{9 \times r \times r}{r} = 9 \times r \times 1 = 9r$

the r on the bottom of the fraction will cancel out one of the r's on top, this happens because anything divided by itself is 1, thus r divided by r is 1

finally we can evaluate when r =3,

9r = 9(3) = 27

How do you graph y= -3x + 5

ZanzabumX [31]

You first find its intercepts: the x intercept is (5/3,0) and the y intercept is (0,5) (just plot those points). Then make the line connecting those 2 points!
