Answer:

The answer to your question is (-1, 2)

Step-by-step explanation:

Data

y = -4x - 2 Equation l

y = 2x + 4 Equation ll

Process

-Graph equation l (green line)

Plot the point (0, -2)

Starting from this point plot the point (1, -4), this point comes from the slope.

-Graph the equation ll (blue line)

Plot the point (0, 4)

Plot the point (1, 2) starting from the previous point.

-The solution is the point where the lines cross. This point is (-1, 2)

15 students were asked how many hours per week they listen to music. 3 different graphs were used to record the same data.

AlladinOne [14]

If you observe the 4 graphical representations you will see that except stem and leaf plot, the rest 3 represent the same information.

As the time is increasing, the frequency of students who listen to music is decreasing. The frequency is maximum for the first group 0 - 1 and least for the last group 6 - 7.

The ranges shown in both Frequency Table and Histogram are the same.

So, the following options are correct:
<span>B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.</span>

Will someone please help me

Answer:

The filled table for each equation by using the exact values in the table is

10x+2y=56

x y

______________________

0 28

$\frac{56}{10}$ 0

________________________

8x+3y=49

x y

_________________________

0 $\frac{49}{3}$

$\frac{49}{8}$ 0

_________________________

Step-by-step explanation:

Given equations are 10x+2y=56 and 8x+3y=49

To fill the table for each equation by using the exact values in the table :

10x+2y=56

put x=0 in above equation we get

10(0)+2y=56

2y=56

$y=\frac{56}{2}$

$y=28$

Therefore (0,28)

put y=0 in the given equation 10x+2y=56 we get

10x+2(0)=56

10x=56

$x=\frac{56}{10}$

Therefore ( $\frac{56}{10}$ ,0)

10x+2y=56

x y

_________________________

0 28

$\frac{56}{10}$ 0

__________________________

For

8x+3y=49

put x=0 in above equation we get

8(0)+3y=49

3y=49

$y=\frac{49}{3}$

Therefore (0, $\frac{49}{3}$ )

put y=0 in the given equation 8x+3y=49 we get

8x+3(0)=49

8x=49

$x=\frac{49}{8}$

Therefore ( $\frac{49}{8}$ ,0)

8x+3y=49

x y

_________________________

0 $\frac{49}{3}$

$\frac{49}{8}$ 0

Kim purchased a $65.00 dress for 20% off. How much did she save?

Ainat [17]

The best thing to do here is to find ten percent, and then double it.
To do this, you divide the number you have by 10.
65.00/10= 6.50
Therefore, you've now got to multiply this by 2.
6.5*2= 13
Therefore, Kim saved $13 on the price of the dress.
Hope this helps :)
