What is the slope-intercept form?

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:

m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.

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.

It takes billy 6 minutes to walk 1.5 km. How long will it take billy to walk 9km?

Answers

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.

Ruby, her brother, and 3 friends will share the bag of candy she bought. There are 110 candies in the bag. How many will each person get? A. 22 B. 24 C. 26

Answers

Answer: A

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.

A 15-foot log is cut into two pieces. How long is each piece if the longer piece is 1.5 feet shorter than twice the shorter piece?

Answers

Given that:

A 15-foot log is cut into two pieces.

Longer piece is 1.5 feet shorter than twice the shorter piece.

Solution:

Let the length of shorter piece be x feet. So,

Length of longer piece = 2x-1.5 feet

Total length = x+(2x-1.5) feet

Now,

[tex]x+(2x-1.5)=15[/tex]

[tex]3x-1.5=15[/tex]

[tex]3x=15+1.5[/tex]

[tex]3x=16.5[/tex]

[tex]x=\dfrac{16.5}{3}[/tex]

[tex]x=5.5[/tex].

So, length of shorter piece is 5.5 feet.

[tex](2x-1.5)=2(5.5)-1.5[/tex]

[tex](2x-1.5)=11-1.5[/tex]

[tex](2x-1.5)=9.5[/tex]

So, length of longer piece is 9.5 feet.

What are Arithmetic operations?

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.

Answers

Answer:

PLEASE SOLVE FOR Y: [tex]7y+4=3-2y[/tex]

Answers

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.

20 fewer roses than daisies. The total flower sales came to $453.00. How
many of each type of flower were ordered and sold.

Answers

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

Step-by-step explanation:

What is Function?

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).
