The system of equations relates the distance, y,
from a station of two trains and the speed, x, at which they are moving.
y + 10x = 250
2.5y = -25x + 625
a. What does the system of equations tell you about the speed
of the trains?
b. What does the solution tell about the locations of the trains if they
left the station at the same time? If they left at different times?

Help please I donrt understand this

Answers

Basically what you do is multiply the distance by the time, for example:

7 1/2 miles = 1/2 hour

so to get the amount of miles in one hour you get the miles and times it by two so it would go like this:

7 1/2 | 15 |

= | = |

1/2 | 1 |

then for one and a half you get the 1 hour answer and add the first one like this:

22.5 miles = 1 1/2 miles

and you continue that pattern!!! If you need more help just reply to this answer i'm in 7th grade so i can help with this stuff

Answer:

The slope is positive, because the line is going up

The equations is.....y = 2/3x - 2

To find slope we can make a table

x      y

6     2

3     0

From 2 to 0, we subtract 2 ( y section)

From 6 to 3, we subtract 3 (x section)

Now we do y/x

so...y/x = -2/-3 = 2/3 (since 2 negatives equal a positive)

Slope = 2/3

And for the y-intercept, I used the graph to help me out, and to find it, you need to see where the line intersects the y-axis which is at -2.

Hope this helped!

A car salesperson sells a used car for ​$ and earns ​% of the sale price as commission. How many dollars does the salesperson earn in​ commission?

Answers

You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.

If the salesman sells a car for $a and gets b% of the sale price as commission, then what you need to do is divide the a by 100, then multiply it by b to find out b% of a. This will be the commission that he will earn.

a / 100 x b = commission earned in $

Edit

You've now supplied me with the $ and %, let me explain it again.

To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.

8,100 / 100 = 81

81 x 9 = $729 commission earned.

Answer:

the square root of 181 = c2

c2 =

Answer:

Potatoes = $0.56 per pound

Broccoli = $2.90 per pound

Pears = $0.98 per pound

Step-by-step explanation:

Potatoes

To find the price per pound of the potatoes, we will need to divide $2.52 by 4.5 to find out how much one pound costs:

$2.52 / 4.5 = $0.56

The formula is the same for all of the other items.

Broccoli

$7.25 / 2.5 = $2.90

Pears

$2.45 / 2.5 = $0.98

Answer:

B.

Step-by-step explanation:

First, (3/2) is greater than 1, which therefore eliminates A and D.

Second, you must determine if the triangle gets larger or smaller. Lets suppose that X = 2 and Y = 3. If we were to multiply both of these values by (3/2), our points would change to X = 3 and Y = 4.5

Since there was an increase, this means that the triangle was larger.

This leaves B as the answer.

Remember: Any scale value greater than 1 is an enlargement, as proven by the hypothetical.
