It is D because
-24 /4n will equal -6n because the n won't go away

8m/4n will equal 2mn because you can always have two variables on one number and the n is not going anywhere

-100p/ 4n will equal -25np because of the same reason as the upper one.

so -6n + 2mn -25np is the simplified expression

Y+1=3(x – 4)<br> 2-intercept:<br> C<br> y-intercept:

kiruha [24]

Answer:

x-intercept is (13/3, 0)

y-intercept is (0,-13)

Step-by-step explanation:

change y+1 = 3(x-4) into slope-intercept form:

y+1 = 3x-12

y = 3x-13

y-intercept is (0,-13)

to get x-intercept, plug zero in for 'y' and solve for 'x':

0 = 3x-13

13 = 3x

13/3 = x

x-intercept is (13/3, 0)

A shape is rotated counterclockwise 110 degrees about the origin. What is another way to describe the rotation?

Kitty [74]

At max a rotation can be equal to π or 180°

So if it's rotated 110° counterclockwise then it's equal to rotation of supplementary angle clockwise

Supplementary angle=180-110=70°

70° rotation clockwise

Answer:

2,075,673,600 batting orders may occur.

Step-by-step explanation:

The order of the first eight batters in the batting order is important. For example, if we exchange Jonathan Schoop with Adam Jones in the lineup, that is a different lineup. So we use the permutations formula to solve this problem.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$
