Answer:

Step-by-step explanation:

None of the expressions on the numerators/ denominators factor

To divide the 2 rational expressions

leave the first fraction

Change division to multiplication

Turn the second fraction upside down, that is

$\frac{2x}{4x+3}$ × $\frac{2x}{x-1}$

Multiply the values on the numerators/ denominators, that is

$\frac{2x(2x)}{(4x+3)(x-1)}$

= $\frac{4x^2}{4x^2-x-3}$ → B

I need help on 11 and 12 and you don’t need to graph it

Lera25 [3.4K]

Answer:

Part 11) see the explanation

Part 12) The graph in the attached figure

Step-by-step explanation:

Part 11)

Let

x ----> the number of tickets is section A (cost $50 each)

y ----> the number of tickets is section B (cost $40 each)

we know that

At most means "less than or equal to"

$x+y\leq 10$ ----> inequality A

$50x+40y\leq 450$ ----> inequality B

Using a graphing tool

The solution is the shaded area

see the attached figure N 1

Three possible combinations are the points

(0,10),(5,5),(9,0)

That means

(0,10) ----> They buy 0 seats in section A and 10 seats in section B

(5,5) ----> They buy 5 seats in section A and 5 seats in section B

(9,0) ----> They buy 9 seats in section A and 0 seats in section B

Part 12)

Let

x ----> the number of hours Kendra works as a babysitter

y----> the number of hours Kendra works providing technical support

we know that

$x+y\leq 80$ ----> inequality A

At least means "greater than or equal to"

$10x+15y\geq 1,000$ ----> inequality B

using a graphing tool

The solution is the triangular shaded area

The city police are trailing the movements of a suspect through the GPS tracker on his phone. The suspect's apartment is represe

Katen [24]

64 is the answer, as all you need to figure out is the length, and width, and multiply them together. Or, just count each unit inside the shape.

I need help with box and whisker plots ASAP

bonufazy [111]

Box and whiskers plots use five number summaries. The first number is:
1:Minimum
2.Quartile 1
3.Mean
4.Quartile 2
5.maximum

Quartile are simple to get.
If your set of numbers is:
2,3,3,6,8,8,11
Then find the mean
2 3 3 |6| 8 8 11
Find the mean of the left side of of mean.
2 |3| 3 3 =Quartile 1
Then the right side
8 |8| 11 8 =Quartile 2
-----------------------------------------------
Your 5 number summary is 2,3,6,8,11
Plot them on the number line, but put a line above where the dot would go. take the 3 middle lines and connect to make a box. The lines on the outside of the box are the whiskers, AKA distributed data.
