Answer:

y = -1x - 8

Step-by-step explanation:

y = -1x + b

-3 = -1(-5) + b

-3 = 5 + b

-8 = b

which of the following doesnot represent pair of integers (a,b) such that a÷b=3​

Answers

Answer: -9,3 and -15,-1 don’t

Explanation

a divided by b = 3

it’s (a,b) so a is out x value and b is the y value, so it’s x divided by y

(-9, 3) ❌

In this case our x is -9 and y is 3

-9 divided by 3 = -3

If the 3 was negative, this would work

(15,-1) ❌

Now our x is -15 and our y is -1

-15 divided by -1 = 15

If it was -3 instead of -1 this would work

(6,2) ✔️

Now x is 6 and y is 2

6 divided by 2 = 3

So this works

(-3, -1) ✔️

Now x is -3 and y is -1

-3 divided by -1 = 3

So this also works

Answers

Answer:

Step-by-step explanation:

The volume of the pool:

16 * 5 * 2.4 = 192

Order equivalent equations of 6(h−4) = 3h to solve for h.

Answers

Answer:

8

Step-by-step explanation:

6h-24=3h

-24=-3h

divide both sides by negative 3

8 = h

The solution for the given equation is h=8.

What is an equivalent equation?

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.

The given equation is 6(h-4)=3h.

The given equation can be solved as follows

6(h-4)=3h

⇒ 6h-24=3h

⇒ 6h-3h=24

⇒ 3h=24

⇒ h=24/3

⇒ h=8

Therefore, the solution for the given equation is h=8.

-2(x -5) = -16

Answers

Answer:

x = 13

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

[tex](-2)(x) + (-2)(-5)= -16[/tex] [tex]-2x + 10 =-16[/tex]

Step 2: Subtract 10 from both sides.

[tex]-2x + 10 - 10 = -16 - 10[/tex] [tex]-2x = -26[/tex]

Step 3: Divide both sides by -2.

[tex]\frac{-2x}{-2}=\frac{-26}{-2}[/tex] [tex]x = 13[/tex]

Step 4: Check if solution is correct.

[tex]-2(13-5)=-16[/tex] [tex]-26 + 10 = -16[/tex] [tex]-16=-16[/tex]

Therefore, x = 13.

Answer:

x=13

Step-by-step explanation:

-2(x -5) = -16

Divide each side by -2

-2(x -5)/-2 = -16/-2

x-5 = 8

Add 5 to each side

What is Inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality.

Given,

A farmer is creating a budget for planting soybeans and wheat.

Planting soybeans costs $200 per acre and planting wheat costs $500 per acre.

Let S be the acre of land to plant soyabean  and W be the acre of land to plant wheat.

200S+500W≤$100,000

This is the required inequality.

(200,100) is the solution of inequality.

Hence 200S+500W≤$100,000 inequality to describe the constraints and (200, 100) is one solution to the inequality.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Evaluating where x = 9 and y = 6

1) 12 - x

12 - 9 = 3
