3x-2y=8 2x+y=10 solve system of equations

Answer:

2/3

Step-by-step explanation:

the slope is change of y divided by change of x

[tex]m = \frac{2}{3} [/tex]

Step-by-step explanation:-

[tex]( - 2, - 1) = (x {1} ,y {1}) [/tex]

[tex](4,3) = (x{2} ,y{2} )[/tex]

BY USING SLOPE OF LINE FORMULA

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

[tex]m = \frac{(3 - ( - 1))}{(4 - ( - 2))} [/tex]

[tex]m = \frac{(3 + 1)}{(4 + 2)} [/tex]

[tex]m = \frac{4}{6} [/tex]

[tex]m = \frac{2}{3} [/tex]

Answer:

.26 cents cheaper a roll

Step-by-step explanation:

to find this you would do 3.64/4 to get the price a roll which is .91

and then you would do 20.80/32 to get the price per roll which is .65

then to get the difference you would do .91-.65 to get .26

Answer:

2x + 5y

Step-by-step explanation:

-5x - 10y + 7x + 15y

add the ones with the same variables

-5x + 7x - 10y + 15 y

2x + 5y

and there you have the answer "2x + 5y"

Answer: Kim got 13 questions wrong.

Step-by-step explanation: First find how many questions were 75% of 52 questions since 3/4 is equal to 75%. Then subtract that amount (which is 39) from 52 and you get 13.

Answer:

2

Step-by-step explanation:

Given

f ( x ) = 7 x + 5

f ( x ) = 19

Now

f(x) = 7x + 5

19 = 7x + 5

7x = 19 - 5

7x = 14

x = 14 / 7

x = 2

Hope it will help :)❤

Answer:

Step-by-step explanation:

7x + 5 = 19

7x = 14

x = 2

Answer: To get 24

Step-by-step explanation

What you would need to do is first multiply 12 x 5 would come out as 60.

Then from 60 you subtract 17 and 12 to get 5. Divide by the 5 that you just got from 17 and 12 and to get 20. Using the 4 add it to the 20 to get 24.

Answer:

$3

Step-by-step explanation:

cost of tank tops

20 / 5 = $4 each

cost of t-shirts

35 / 5 = $7 each

7 - 4 = $3

Answer:

$3

Step-by-step explanation:

1.Approach

To solve this problem, one must first find the cost of each product. This can be done by diving the price by the amount of each product. After finding the unit price of each product, one will subtract the cost of the tank-top from the cost of the t-shirt.

2.The unit price of a t-shirt

It is the given that 5 t-shirts cost $35. Divide the price of the shirts by the number of shirts to find the cost of each individual shirt.

35 ÷ 5 = 7

Each individual t-shirt costs $7.

3.The unit price of a tank-top

It is given that 5 tank-tops cost $20. Divide the price of the tank-tops by the number of tank-tops to fund the unit price of each tank-top.

20 ÷ 5 = 4

Each tank-top costs $4.

4.Find out how much more each shirt costs

Now subtract the price of the unit price of the tank-top from the unit price of the t-shirt.

(t-shirt) - (tank-top)

= 7 - 4

= 3

Answer:

Compound interest earns interest on the principal plus any previous interest earned.

Step-by-step explanation:

compound interest gets its name because the interest keeps on 'compounding' which means earning interest on interest

The correct best describes the difference between simple and compound interest is,

⇒ Compound interest earns interest on the principal plus any previous interest earned.

Option 3 is true.

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

We have to given that;

To defined best describes the difference between simple and compound interest.

Now, We know that;

Compound interest pays interest on your previous balance plus your previous earned interest; simple interest pays interest only on your original balance.

Hence, The correct best describes the difference between simple and compound interest is,

⇒ Compound interest earns interest on the principal plus any previous interest earned.

Y-Intercept = (0,y)

= (0, -2)

Answer: The required co-ordinates of the new point are (6, 5).

Step-by-step explanation: Given that the point (-3, 15) undergoes a translation of 9 units right and 10 units down.

We are to find the coordinates of the new point.

We know that

if the point (x, y) undergoes a translation of 9 units right and 10 units down, then its translation rule is given by

(x, y) ⇒ (x+9, y-10).

Therefore, the co-ordinates of he new point are given by

(-3, 15) ⇒ (-3+9, 15-10) = (6, 5).

Thus, the required coordinates of the new point are (6, 5).

Answer:

$90000

Step-by-step explanation:

From the pie chart,

Let the total annual income =  $y

The percentage of housing = 28 %

The percentage of clothing = 14 %

The combined percentage of housing and clothing = 28+14 = 42 %

If the amount spent on both housing and clothing combined = $ 37800

Therefore,

y(42/100) = 37800

Solve for y

42y = 37800×100

42y = 3780000

y = 3780000/42

y = $90000

Hence, the total annual income is $90000

Answer: 222cm

Step-by-step explanation:

To find the area of this composite shape you will have to split them into 2 shapes; a rectangle and a triangle.

To work out the area of the rectangle you have to do 15×12= 180

Then, to work out the area of the triangle, you use the formula base times height divided by 2.

7×12=84

84÷2=42

Then to work out the total area of both the rectangle and the triangle, you have to add the area of both.

180+42=222cm
