Ryan and Taylor are both saving money to buy new video game

dollars. The table shown represents Taylor's savings plan.

Ryan's rate of change is ________ Taylor's rate of change .

Ryan'sstaring balanced is_______ Taylor's starting balanced.​

Answers

We want to compare the rates of change and starting balances of Ryan and Taylor, the correct answers are:

"Ryan's rate of change is _less than_ Taylor's rate of change.""Ryan's starting balance is greater than Taylor's starting balance.​"

So we know that Ryan's savings plan can be modeled by:

S(m) = 15*m + 50.

This means that he starts with 50, and saves 15 per month, then:

Ryan's rate of change = 15 per monthRyan's initial balance = 50

For Taylor we have a table:

month    amount saved:

0                 25

1                  45

2                 65

3                 85

So, in month 0 he has 25, thus, his initial balance is 25.

And each month the amount saved increases by 20, then the equation is:

T(m) = 20*m + 25

Then we have:

Taylor's rate of change = 20 per month.Taylor's initial balance = 25

Now we can see that:

"Ryan's rate of change is _less than_ Taylor's rate of change."

"Ryan's starting balance is greater than Taylor's starting balanced.​"

The scatter graph for level of water in a dam on each day and date for one month type of data is most likely to suggest a linear association.

What is scatter plot?

A scatter plot, like a scatter chart or graph, employs dots to represent the values of two numerical variables. The horizontal value represents the data from individual points. Hence, it is used to observe the relationships between variables.

The scatter plot can provide the values for the data set. The points can be of various sizes, colours, and forms. The information is presented in the form of points.

The values are represented on the vertical axis. The data association can be positive, negative, or neutral. A mosaic and a fluctuational diagram can be displayed on the scatter plot.

Thus, the plot which can be linear association form level of water in a dam on each day and date for one month

{45x+6y=15-x+18y=11 is..........................

Answers

Answer:

Step-by-step explanation:

45x+6y=15

-x+18y = 11

let's use elimination, the other way is by substitution,  either way works but, it looks to me like elimination would be easy with the  'y'

3(45x+6y=15)

135x + 18y = 45 ( subtract  2nd eq.  from 1st )

-( -x+18y = 11 )

136x +0y =34

x = 34 /136

x = 1 /4

there is X

plug that back into either of the 1st or 2nd equations to solve for y

- 1/4 + 18 y = 11

18y = 11 1/4

18y = 45/4

y = 45/4 *  1/18

y = 45/ 72
