The slope of the line x = 5 is undefined.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + b

Where:

Based on the information provided about this line, a linear equation that models it is given by;

y = mx + b

x = 5

This ultimately implies that, this line is a vertical line and as such, it has no slope or an undefined slope. Therefore, the x-intercept is 5 and the slope is undefined.

Answer:

[tex]y = \frac{-1}{9}[/tex]

Step-by-step explanation:

[tex]7y + 4 = 3 - 2y[/tex]

add [tex]2y[/tex]  to both sides

[tex]7y + 4 + 2y = 3 -2y + 2y \\9y + 4 = 3[/tex]

add [tex]-4[/tex] to both sides

[tex]9y + 4 -4 = 3 - 4 \\9y = -1[/tex]

divide both sides by [tex]9[/tex]

[tex]\frac{9y}{9} = \frac{-1}{9} \\[/tex]

[tex]y = \frac{-1}{9}[/tex]

The solution to the equation 7y + 4 = 3 - 2y is y = -1/9.

Here, we have,

To solve for y in the equation 7y + 4 = 3 - 2y, we can follow these steps:

Step 1: Combine like terms on both sides of the equation:

7y + 2y = 3 - 4.

Simplifying:

9y = -1.

Step 2: Divide both sides of the equation by 9 to isolate the variable y:

(9y)/9 = (-1)/9.

Simplifying:

y = -1/9.

Therefore, the solution to the equation 7y + 4 = 3 - 2y is y = -1/9.

Answer:

A, the other person was correct

Step-by-step explanation:

The polynomial functions is graphed below is f(x) = (x+ 4)(x- 2)².

a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

There are three components that make up a function: a set of inputs, a set of outputs, and a rule that links the elements of the input set to the elements of the output set so that each input is paired with exactly one output.

We have a graph for polynomial function.

We know that the function of graph have solution where the graph touches or passes the x axis.

Here from the graph at x = -4 and at x= 2 the touches and moves upward.

So, the factors of polynomial are (x+ 4) and (x- 2).

Thus, the polynomial function is f(x) = (x+ 4)(x- 2)².

Answer:

7 teams of 4 but there would be an extra person

Step-by-step explanation:

the answer is -1000 as -10 cube is -1000

The value of product of (-10)(-10)(-10) is -1000.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations are called arithmetic operators.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts right-hand operand from left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

To determine the product of (-10)(-10)(-10)

⇒ (-10)(-10)(-10)

Multiplying the last two terms and (-) signs cancel out each other,

⇒ (-10)(100)

Multiplying the two terms,

⇒ -1000

Hence, the value of product of (-10)(-10)(-10) is -1000.

Answer:

Step-by-step explanation:

14 by 21. 14 shorter length

Answer:

It will take Billy 36 minutes to walk 9km.

Answer:

[tex]\boxed{\tt 36 \ minutes}[/tex]

Step-by-step explanation:

Let's make a proportion using the following setup:

[tex]\frac{minutes}{kilometers} =\frac{minutes}{kilometers} \\[/tex]

We know it takes Billy 6 minutes to walk 1.5 kilometers.

[tex]\frac{6\ minutes}{1.5\ kilometers} =\frac{minutes}{kilometers}[/tex]

We don't know how long it takes him to walk 9 kilometers, so we can say it takes him x minutes to walk 9 kilometers.

[tex]\frac{6\ minutes}{1.5\ kilometers} =\frac{x\ minutes}{9\ kilometers}[/tex]

[tex]\frac{6}{1.5} =\frac{x}{9}[/tex]

Now, solve for x. To do this, isolate x on one side of the proportion. x is being divided by 9. The inverse of division is multiplication. Multiply both sides of the proportion by 9.

[tex]9*\frac{6}{1.5} =\frac{x}{9}*9[/tex]

[tex]9*\frac{6}{1.5} =x[/tex]

[tex]9*4=x[/tex]

[tex]36=x[/tex]

x= 36 minutes

It will take Billy 36 minutes to walk 9 kilometers.

Step-by-step explanation: since there’s 110 candies divide it between the 3 friends plus ruby and her brother. So divide 110 by 5 and it will be your final answer

Answer:

A. 22

Step-by-step explanation:

First, you don't want to fall into the trap. The question says Ruby, her brother, AND 3 friends. That means you have to add everyone. 3(friends)+2(Ruby and her brother)=5 people. Then you have to divide. 110/5=22.

So, A.22 candies each.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Total flowers sold = 200

Flowers are :

Carnations, Roses, and Gerber daisies

Carnations = c

Roses = r

Daisies = d

20 fewer roses than daisies ; r = d - 20

Total sales = $453

c = $1.50 each ; r = 3.75 each ; d = 2.25 each

c + d + d - 20 = 200

c + 2d = 220 - - (1)

1.50c + (d - 20)(3.75) + 2.25d = 453

1.50c + 3.75d - 75 + 2.25d = 453

1.50c + 6d = 528 - - - (2)

From (1)

c = 220 - 2d

1.5(220 - 2d) + 6d = 528

330 - 3d + 6d = 528

330 + 3d = 528

3d = 528 - 330

d = 198/3

d = 66

66 × 2.25 = $148.5

c = 220 - 2(66)

c = 88

88 * 1.50 = $132

r = d - 20

r = 66 - 20

r = 46

46 × $3.75 = $172.5

Answer:

Positive Integer factors of 630 = 2, 3, 6, 18, 5, 90, 7, 630 divided by 2, 3, 3, 5, 7, gives no remainder. They are integers and prime numbers of 630, they are also called composite number.

Rounding off numbers is a process used to simplify or approximate a numerical value to a specific degree of precision or to a specified number of decimal places. It involves adjusting a number to a nearby value that is easier to work with or more meaningful in a particular context.

When rounding off, you typically consider a specific digit in the number and look at the digit to the right of it. Depending on the value of that digit, you either increase or keep the original digit unchanged.
