solve this and get brainly

Answers

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.

A. T> 600

B. T<600

Answers

Answer:

A

Step-by-step explanation:

Answer: B. T<600

Step-by-step explanation:

if the monthly plan is $30, we subtract that from $60 to get that she has $30 left. Then divide 30 by 0.05 to get exactly 600. but, you can’t forget that other $0.05 per month so it would have to be less than 600 texts

I got you,
Potatoes: $1.23
Broccoli: $3.10
Pears: $0.98

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

A bag contains​ pennies, nickels,​ dimes, and quarters. There are 50 coins in all. Of the​ coins, ​8% are pennies and ​40% are dimes. There are 3 more nickels than pennies. How much money does the bag​ contain?

Answers

The bag contains $2.39

Explanation 40% of 50 coins is 20 dimes which equals 2 dollars

8 percent is 4 pennies

2.00+ .04 is 2.04

Plus 7 nickels because there are 3 more nickels than pennies 7*5= 35

2.04+.35= 2.39

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

Answers

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.
