B) No, the ordered pair is not a solution.

Answers

Given:

The inequality is:

[tex]-4x-7y<15[/tex]

To find:

The whether (-6,3) is a solution of given inequality of not.

Solution:

We have,

Calculate the marked price (original price) if
a. After 25% discount, the price of an article is Rs 7500,

Answers

Answer:

Step-by-step explanation:

let original price of an article be x

marked price(price after discount )=Rs 7500

discount%=25%

discount =discount % of cost price

=25/100*x

=25x/100

=x/4

Mark price=original price-discount amount

Rs 7500=x-x/4

Rs 7500=4*x-x/4

Rs 7500*4=4x-x

Rs 30000=3x

Rs 30000/3=x

Rs10000=x

therefore original price of an article is Rs 10000.

y=mx+b

m = slope

b = y intercept

m = 5

b = -8

y=5x-8

Step-by-step explanation:

y = mx + b

m is the slope

b is the y-intercept

M is 5 and B is -8

So, y = 5x - 8

If you add the two equations 6x + 4y 46 and — 6x + 9y = 6 what do you get? ​

Answers

Answer:

13y = 52

Step-by-step explanation:

6x - 6x + 4y + 9y = (46 + 6)

6x - 6x + 4y + 9y = 52

0 + 4y + 9y = 52

0 + 13y = 52

13y = 52

Mateo compró un artefacto gastando los 3/7 de su dinero, quedándole 360 soles, ¿Cuál era el dinero que tenía Mateo al inicio?

Answers

Answer:

840 soles

Step-by-step explanation:

Sea la cantidad de dinero que Mateo tenía al principio = x

Mateo compró un artefacto gastando 3/7 de su dinero, dejándole 360 ​​soles,

Por eso,

3/7 × x = 360 soles

3x / 7 = 360 soles

Multiplicar cruzada

3x = 7 × 360 soles

x = 7 × 360 soles / 3

x = 840 soles

Por tanto, el dinero que tenía Mateo al principio es de 840 soles

THIS IS DUE TOMORROW MORNING!!! Find the slope and and y-intercept of the line 2x + 6y = -12​

Answers

Answer:

Slope: -1/3

y intercept: (0, -2)

What is the first step you will use to solve this equation:

4x +2 = 7x - 13

Answers

Moving the variable to the left hand side and change its sign so id be 4x + 2 - 7x = -13

1. Subtract 2 from both sides of the equation

4x + 2 = 7x - 13

4x + 2 - 2 = 7x - 13 - 2

2. Simplify

4x + 2 - 2 = 7x - 13 - 2 -----> 4x = 7x - 13 - 2 -----> 4x = 7x - 15

3. Subtract 7x from both sides of the equation

4x = 7x - 15

4x - 7x = 7x - 15 - 7x

4. Simplify

4x - 7x = 7x - 15 - 7x -----> -3x = 7x - 15 - 7x -----> -3x = -15

5. Divide both sides of the equation by the same term

-3x = -15

-3x/-3 = -15/-3

6. Simplify

-3x/-3 = -15/-3

x = -15/-3

x = 5

7. Solution

x = 5

Greggory is trying to raise money for his​ school's football team by selling​ T-shirts and sweatshirts. The football team will get​ $3 for each sweatshirt sold and​ $4 for each​ T-shirt sold. The rest of the money goes to paying for the items to be sold. Greggory manages to sell a total of 121 items and the team ends up getting​ $406.

Answers

# of sweatshirts sold = x = 78
# of t-shirts sold = y = 43

We know:
x + y = 121
3x + 4y = 406

Solve the first equation for x in terms of y, then substitute that into the second equation.

x = 121 - y

3(121 - y) + 4y = 406
363 - 3y + 4y = 406
y + 363 = 406
y = 43

Then solve for x

x = 121 - y
x = 121 - 43
x = 78

Check the math:
3(78) + 4(43) = 234 + 172 = 406

A ladder is placed 10 feet away from a tree. The length of the ladder is 25 feet. Find the height of the tree?

STEP BY STEP PLS

Answers

Answer:

23ft approx

Step-by-step explanation:

Given data

Distance from tree= 10ft

Length of ladder= 25ft

We can find the height of the tree by applying the Pythagoras theorem

z^2= x^2+y^2

z= The height of the ladder

x= The distance from the tree

y= The height of the tree

25^2= 10^2+ y^2

625=100+y^2

625-100=y^2

525=y^2

y= √525

y= 22.91

Hence the height of the tree is 23ft approx
