The graphs of the equations Ax + By =15 and Ax - By =9 intersect at (2, 1). Find A and B. Show or explain your reasoning
The value of A and B will be 6 and 3 respectively
What is Linear equation with two variables?If an equation is stated in the form ax + by + c=0, it is said to be a linear equation in two variables, where a, b, and c are real numbers and the coefficients of x and y, i.e. a and b, are real values.Linear equations in two variables are the algebraic equations which are of the form y = mx + b, where m is the slope and b is the y-interceptHow to solve this problem?The steps are as follow:
Given equationsAx +By = 15
Ax - By = 9
Given that both lines intersect at point (2,1), so both above equation can be written as:2A + B = 15
2A - B = 9
Solving the above equation by adding both of them we get:4A = 24
A = 6
Putting value of A in one of equation we will get:2A + B = 15
2(6) + B = 15
B = 3
So the value of A and B will be 6 and 3 respectively

The graph shows the amount of money you and a friend are saving for a camping trip. You: 2 weeks 40 dollars. 5 weeks 100 dollars
Friend: 4 weeks 60 dollars. 8 weeks 120 dollars.
A) Compare the steepness of the lines. What does this mean in the context of the problem.
B) Find the slope of each line.
C) How much more money does your friend save each week than you?
D) The camping trip costs $165. How long well it take you to save enough money

We want to compare two linear equations and answer some things in regards to these.
A) Your line should be steeper.B) your slope is $20 per week, your friend slope is $15 per week.C) Your friend wins $5 less than you per week.D) You must save for 9 weeks, your friend for 11 weeks.So we have two sets of data:
you: (2 weeks, $40), (5 weeks, $100)friend: (4 weeks, $60), (8 weeks, $120)A) First we want to compare the steepness of the lines, it will represent how much money you and your friend gets per week, a more steep line means a larger weekly income.
By the given points, you can see that you have an increase of $60 in 3 weeks, while your friend has an increase of $60 in 4 weeks, thus, your line should be steeper.
B) We know that for a line that passes through points (x₁, y₁) and (x₂, y₂) the slope is given by:
[tex]s = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, for you, the slope is:
[tex]s_y = \frac{\$100 - \$40}{5 weeks - 2 weeks} = \$20\ per \ week[/tex]
For your friend the slope is:
[tex]s_f = \frac{\$120 - \$60}{8 weeks - 4 weeks} = \$15 \ per \ week[/tex]
C) Your friend saves $5 less than you per week.
D) You, by week 5, have $100
So you need to save another $65
And you save $20 per week, so we need to solve:
$20*x = $65
x = $65/$20 = 3.25
Rounding to the next whole number, x = 4
And this is 4 weeks after the 5th week, so you need to save for a total of 9 weeks.
For your friend, he has $120 at the 8th week, then he must save another $45, and he saves $15 per week, so we need to solve:
$15*x = $45
x = $45/$15 = 3
He must save for another 3 weeks, for a total of 11 weeks.

Select all possible values of k.
Answer:
Its easy... 5 and 5.04!
Step-by-step explanation:
You have to look at it properly. It says "The value of SQUARE ROOTED K."
So all you have to do is square root them and whatever is in between 2.2 and 2.3 is ur answer. Ur answer 5 and 5.04.
The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that √k falls between 2.2 and 2.3
For k = 1.49, √1.49 = 1.22 which is not between 2.2 and 2.3
For k = 4.8, √4.8 = 2.19 which is not between 2.2 and 2.3
For k = 5, √5 = 2.2 3which is between 2.2 and 2.3
For k = 5.04, √5,04 = 2.23 which is between 2.2 and 2.3

Ruben put an empty cup underneath a leaking faucet. After 1 1\2 hours, Ruben collected 1/4 cup of water. What is the rate, in cups per hour, at which the water is leaking from the faucet?
Answer:
1/6 cups per hour

Given that :
Time = 1 1/2 hours = 1.5 hours
Cups of water collected = 1/4 cups
Rate in cups per hour :
Cups collected / time
1/4 ÷ 1 1/2
1/4 ÷ 3/2
1/4 * 2/3

55% of 6th grade students voted in the student election. 440 sixth grade students voted in the student election. How many total 6th graders are in the school
Answer:
800. Here's why:
Step-by-step explanation:
This indicats that 440 students make up 55% of the 6th grade population. We can write this as
55/440.
We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as
100/x.
55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders
Answer:495
Step-by-step explanation:
440 rounds up to 450,450+450=900-the 10 we rounded so 890-440 is 450 which is half so we need to add 440 to 550 to get 990 and we half 990 to get 495 and that is your answer i think im very sorry if this is wrong btw a sixth grader did this please find out a way to reply to my comment or something like that to tell me if i am right.
