Answer:

-12t + 21

Step-by-step explanation:

9-4(3t-3)

In order to get rid of the parenthesis you must take -4 and multiply it by the number(s) inside the parenthesis

So, -4 times 3t equals -12t and -4 times -3 equals +12

9-12t+12

Combine like terms

-12t + 21

Hope this helps!

Mandy told Bill that she has read 16 books this year and reads 2 books each month. Bill wants to catch up to Mandy. He tracks hi
Lostsunrise [7]
We need to write equation for both mandy and bill on how many books they read depending on how many months passed.

Mandy's equation:
16 + 2x

she starts with 16 read books and she reads 2 books each month which is in total 2*x where x is number of months

Bill's equation:
4x
because from table we can see he is reading 4 new books each month.

now we need to make those 2 equations equal to eachother and solve for x because we want to see after how many months both will read the same that is why we set them equal.

16 + 2x = 4x
16 = 2x
x = 8

That means that in december he will catch her (if i counted months correctly :) )

Point C is the midpoint of AB.point A has coordinates (2,4)and point C has coordinates (5,0) what are the coordinates of point B
devlian [24]

Answer:

The coordinates of point B is (8,-4)

Step-by-step explanation:

Midpoint of a line segment: It is the point on the line segment that divides the segment in two congruent segments.

Since it is given that C is the midpoint of Line segment AB.

Mid-point of a segment of end points A(x_{1},y_{1}) and B(x_{2},y_{2}) is, C= (\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}).

As, given the coordinates of A and C are (2,4) and (5,0)

then,  we have x_{1}=2 , y_{1}=4 ; \frac{x_{1}+x_{2}}{2}=5  and \frac{y_{1}+y_{2}}{2}=0

to find the coordinates of B(x_{2},y_{2}).

\frac{2+x_{2}}{2}=5

Simplify:

2+x_{2}=10

⇒ x_{2}=8

to solve for y_{2} we have, \frac{y_{1}+y_{2}}{2}=0

or y_{1}+y_{2}=0

or y_{2}= -y_{1}= -4

so, the values of x_{2}=8 and y_{2}=-4

Therefore, the coordinates of point B is (8,-4)
