Find the slope of the line.

Please help

Answer:

(-10, 9)

Step-by-step explanation:

9x+9y=-9

Use substitution method

9(-10)+9y=-9

Order of operations(PEMDAS)

-90+9y=-9

Add 90 to both sides

(-90+90)+9y= -9+90

9y=81

Divide 9 from both sides

(9/9)y=81/9

y=9

Hope this helps. Have a nice day. May it be filled with joy and happiness. Please, stay safe and wash your hands. Happy Holidays.

Answer:

Step-by-step explanation:

in this case, we already know that x=   -10 so we can substitute in the other problem, -10x9 = -90 so now we can get rid of that by adding + 90 on each side making it 9y=81 by this time, we see that both sides are divisable by 9 divide both by nine and you get: 1y=9 from that you can finally answer the question with

x= -10 y= 9

Answer:

$3,000 was invested in the account that gained 13%

$17,500 was invested in the account that lost 10%

Step-by-step explanation:

Let the amount in both accounts be x and y

x for the first and y for the second

Adding both is 20,500

x + y = 20,500 •••••(i)

First account earned 13% profit

= 13/100 * x = 0.13x

Second account, a loss of 10%

= -10/100 * y = -0.1y

Total loss of -1,360

This is;

-0.1y + 0.13x = -1,360 •••••••(ii)

From i, x = 20,500-y

Insert this into ii

-0.1y + 0.13(20,500-y) = -1,360

-0.1y + 2665 -0.13y = -1360

-0.23y = -1360-2665

-0.23y = -4025

y = -4025/-0.23

y = 17,500

To get x, we have

x = 20,500 -y

x = 20,500- 17,500

x = 3,000

Answer: you would look for y and then once you have y you put it into desemos which is a graphing app and then you get your line

Step-by-step explanation: you would do +3x on both sides with out doing it to the 4y and the. You would get 4y =23+3x and then you divide everything by 4 even the 4y and then you would get y= 23/4 + 3/4x and then you put it into desemos and it will give you it graphed

Answer:

43°

Step-by-step explanation:

(x + 53)° + (x + 74)° + 73° = 180°

(x + 53 + x + 74)° = 180° - 73°

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127

2x = - 20

x = - 20/2

x = - 10

[tex]m\angle A = (x +53)\degree \\\\

m\angle A = (-10 +53)\degree \\\\

m\angle A = 43\degree \\\\

A student pays for 8.9 pounds of apples with a 10$ bill. Its $1.09 per pound. How much change does the student receive? What do you do first to solve the​ problem?

Answer:

$0.299

Step-by-step explanation:

Given that :

Pounds of apple purchased = 8.9 pounds

Price per pounds of apple = $1.09

Bill issued = $10

First, we calculate the total cost of 8.9 pounds of apple :

(Number of pounds * price per pound)

($8.9 * 1.09) = $9.701

Amount of Change :

Bill issued - total cost

$10 - $9.701

= $0.299

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

You would have to multiply 30 by however many months he deposits money to find how much he has in he account at that time

Hope this helps

The function rule of the total amount T in the account after n months is

T = 30n + 58.

Option A is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amount in the account = $58

Amount deposited each month = $30

The total amount after n months.

T = 58 + 30n

Thus,

The T = 30n + 58 is the total amount in the account after n months.
