Linear equations
Answer:
- So were x is 0 that is your y-intercept.
y-intercept: 5
- For your slope it is alway Rise over Run and if your slope is negative you might go down instead of up. So for this table your slope is a zero slope because it is going directly across the graph horizontally. Think of it as a stick figure, with a positive slope they walk up the line with a negative they walk down and zero they walk strait on flat ground. so therefore there is no slope.
You always have your y-intercept in you equation
y=mx+b mx is slope and b is your y-intercept
since your line is not negative or positive and is horizontal a zero slope meaning there is like no slant or angle to your line your equation will look like this.
y=5
because there is no mx (slope) and only a y-intercept
slope: 0
y-intercept: 5
Equation: y=5

A student estimated the temperature of the room to be 24°C. After carefully measuring, he found the actual temperature to be 23.5°C. What is the percent of error?
Answer:
2.13% (rounded to nearest thousandth)
Step-by-step explanation:
You subtract 24 from 23.5 to get 0.5
Then you divide 0.5 by 23.5 to get 0.02127
Then you multiply that by 100 to get your percent error
Taking 24 then using the process of elimination the total percentage that he was off by was 1.05% off
Find the sum (4d+9)+(7n-4)+(9y+5)
Answer:
4d + 7n + 9y + 18
Step-by-step explanation:
Add like terms, like terms are terms that have the same variable and power, For ex: 4d and 2d are like temrs so u can add them but 4d and 4d^2 are not cause they have different power(the ^2 thing).
(4d+9)+(7n-4)+(9y+5)
add like terms
4d + 7n + 9y + 18

2x = 18
x = 9
Answer:
x = 9
Step-by-step explanation:
8x = 6x + 18 (subtract 6x from each side)
2x = 18 (divide each side by 2)
x = 9
Tell whether the value is a solution of the inequality. Pls helpp
Answer: it is most likeply a solution
Step-by-step explanation:
Answer:
No, the answer is a solution to the inequality.
Step-by-step explanation:
When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the inequality.
2x > 5; x = -4
2(-4) > 5
-8 < 5
The answer is false, because there is no solution to -8 < 5. Therefore, the value is not a solution of the inequality.

The Stock Market nadia is a stockbroker. Earns 14% commission each week. Last week, sold 7200$ worth of stocks. How much did make last week in commission? If averages that same amount each week, how much did make in commission in 2011?
Answer:
Step-by-step explanation:
C=0.14×7,200=1008
Nadia made a total of $1008 last week in commission sales
b). To express the total amount she made in 2011, we derive the formula below;
Total amount (2011)=Average weekly commission× number of weeks in 2011
where;
Average weekly commission=$1008
number of weeks in 2011=52
replacing;
Total amount (2011)=(1008×52)=52,416
The total amount Nadia in commission in 2011=$52,416

A homeowner is making plans to landscape her yard. She plans to hire professionals to install grass sod in some parts of the yard and flower beds in other parts. Grass sod installation costs $2 per square foot and flower bed installation costs $12 per square foot. Her budget for the project is $3,000. Write an equation that represents the square feet of grass sod, x, and the square feet of flower beds, y, that she could afford if she used her entire budget.
Answer: 2x+12y<3000
Step-by-step explanation:
x intercept: (1,500,0)
y intercept: (0,250)
The linear equation that represents the total cost will be 2x + 12y = 3000.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
A mortgage holder is making arrangements to scene her yard. She intends to recruit experts to introduce grass turf in certain pieces of the yard and blossom beds in different parts. Grass turf establishment costs $2 per square foot and blossom bed establishment costs $12 per square foot. Her spending plan for the venture is $3,000.
Let 'x' be the square feet of grass sod and 'y' be the square feet of flower beds. Then the total cost is given as,
2x + 12y = 3000
The linear equation that represents the total cost will be 2x + 12y = 3000.

I WILL GIVE BRANLIEST IF YOU ANSWER THIS!!!!!! a grandfather is 9 times older than his granddaughter. In 8 years the grandfather will be 5 times older than his granddaughter. How old is each of them now?
PLSSS I NEED QUICK:(
Answer:
The granddaughter is 6 years old and the grandfather is 60 years old.
Step-by-step explanation: Present the age of the granddaughter as X years.
10x = x + 54
10x - x = 54
9x = 54
x = 54/9 = 6 years.
So, granddaughter’s age = 6 years and grandfather’s age = 10 x 6 = 60 years.

A rescuer is trying to save a cat at the very top of a tree. The height of the tree is 35 feet. A rope is thrown to the top of the tree at a 25° angle from a tether on the ground.
1. Draw a diagram to model the problem.
2. What is the length of the rope needed to meet the tree? Show all work and label the answer. Round to the nearest tenth, if needed.
[tex] \sin(c) = \frac{opposite}{hypotenuse} [/tex]
[tex] \sin(25) = \frac{35}{b} [/tex]
[tex](b) \sin(25) = \frac{35}{b}(b)[/tex]
[tex](b) \sin(25) = 35[/tex]
[tex] \frac{(b) \sin(25) }{ \sin(25) } = \frac{35}{ \sin(25) } [/tex]
[tex]b = \frac{35}{ \sin(25) } [/tex]
[tex]b = 82.8[/tex]
the length of the rope needs to be around 82.8

Write 81+72 as a proudect using gcf as one of the factors
Step-by-step explanation:
Since 81 = 9² and 72 = 9 * 8,
81 + 72 = 9(9 + 8) = 9 * 17.
An expression is defined as a set of numbers, variables, and mathematical operations. The expression 81+72 as a product using GCF as one of the factors can be written as 9(9+8).
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Answer:
A) 2.8 m
Step-by-step explanation:
The formula for the volume of a right rectangular prism is:
Volume = Length × breadth × height
We can just put in the values that we know to find the height.
110.1 = 7.8 × 5.1 × height
height = 110.1 ÷ 7.8 ÷ 5.1
height ≈ 2.8 (rounded to nearest tenth)
Thus, the answer is Option A.
