Choose a method that can be used to solve this system of equations by elimination.
2x - 2y = 24
4x + 7y = -40
1. Subtract 2x from both equations and solve the first equation for y.
2. Multiply the first equation by -2 and add the second equation.
3. Add the first equation to the second equation and subtract 6x from both sides of the equation.
4. Subtract 7y from the second equation and add the first equation.
Which one of these steps is the correct way of solving by elimination?
Answer:
2
Step-by-step explanation:
if we multiply the first equation by neg 2, the 4x's cancel out.
The method that should be selected is
2. Multiply the first equation by -2 and add the second equation.
Elimination method:In the elimination method, we can either add or subtract the equations to get an equation in one variable. At the time When the coefficients of one variable are opposites, so we can add the equations to eliminate a variable and when the coefficients of one variable are equal we can subtract the equations to eliminate a variable.

Suppose that 20% of students at high school A and 18% of students at high school B participate on a school athletic team. Independent random samples of 30 students from each school are selected and asked if they participate on a school athletic team. Let ˆ p A represent the sample proportion of students at school A who participate on a school athletic team and ˆ p B represent the sample proportion of students at school B who participate on a school athletic team.
What is the mean of the sampling distribution of ˆ p A − ˆ p B ?
Answer:
0.02
Step-by-step explanation:
High schools A :
Percentage of participants in on the school athletic team = 20%
Pa = 20% = 0.2
High school B:
Percentage of participants in on the school athletic team = 18%
Pa = 18% = 0.18
The mean of sampling distributon is :
Pa - Pb
0.2 - 0.18
Hence, Mean of sampling distribution is 0.02

Answer: Jasmine hikes at a rate 0.5 miles per hour faster than Deandre (the third option).
Step-by-step explanation: Deandre hikes at a rate of 2.5 miles per hour, since the slope in the equation is 2.5. For Jasmin, the slope on the graph is 3 (since it goes up 3, over 1), which means she hikes at a rate of 3 miles per hour. 3 is 0.5 greater than 2.5, so Jasmin hikes at a rate that is 0.5 miles per hour faster than Deandre.
**On the graph, the blue line is Jasmin and the red line is Deandre.

Answer:
ead the excerpt from "The Most Dangerous Game,” by Richard Connell.
His foot touched the protruding bough that was the trigger. Even as he touched it, the general sensed his danger and leaped back with the agility of an ape. But he was not quite quick enough; the dead tree, delicately adjusted to rest on the cut living one, crashed down and struck the general a glancing blow on the shoulder as it fell; but for his alertness, he must have been smashed beneath it. He staggered, but he did not fall; nor did he drop his revolver. He stood there, rubbing his injured shoulder, and Rainsford, with fear again gripping his heart, heard the general's mocking laugh ring through the jungle.

The formula for the gravitational potential energy of an object is U = mgh, where U represents the potential energy, m represents the mass of the object, g represents the acceleration due to gravity, and h represents the object’s height above the ground. Solve this formula for h.
U=mgh
U/m=gh
U/mg=h
therefore:
h=U/mg
The solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.
Here, we have,
To solve the formula U = mgh for h (the height above the ground),
we need to isolate h on one side of the equation.
Here are the steps:
Start by dividing both sides of the equation by mg:
U / (mg) = (mgh) / (mg)
This simplifies to:
U / (mg) = h
Now we have isolated h on one side of the equation.
Therefore, the formula for h is:
h = U / (mg)
So, the solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.

The ordered pairs (8,12). (16, 24), (x, 21), (26, y) represent a proportional relationship
Find the value of x and the value of y.
Select the two correct answers.
A y=56
B. x= 14
C. x=7
D. y=39
Ex= 9
F. y = 42
Answer: B. x= 14
D. y=39
Step-by-step explanation:
First and foremost, we need to calculate the constant of proportionality. This will be:
(8,12).
y = kx.
12 = 8k
k = 12/8
k = 1.5
(16, 24),
y = kx
24 = 16k
k = 24/16
k = 1.5
(x, 21),
y = kx
x = y/k
x = 21/1.5
x = 14
(26, y)
y = kx
y = 26 × 1.5
y = 39

Step-by-step explanation:
at her job Jessie earns 9.75 an hour. she also earns a bonus of 80 dollars every month.
Jessie needs to earn at least 500 dollars a month. create an inequality that represents this situation, where h represents the number of hours that Jessie works in a month in order to earn at least 500 dollars
Answer:
9.75h + 80 ≥ 500
Step-by-step explanation:
Hi! If we look at the problem, it says that "Jessie earns 9.75 an hour." If it is asking you to use h as the hour, it results to 9.75h. Next, she gets a bonus of 80 dollars every month. 9.75h + 80. Lastly, it says she "needs to earn at least 500 dollars". at least is a fancy way of saying greater than or equal to '≥'.

Find the missing sides using special right triangles
Answer:
The answers are;
m = 9, e = 9
Step-by-step explanation:
The question relates to right triangles with special properties;
The given parameters of the given right triangles are;
The measure of an interior angle of the triangle = 45°
The length of the given leg length of the triangle = (9·√2)/2
The length of the other leg length of the triangle = n
The length of the hypotenuse side = m
A right triangle with one of the measures of the interior angles equal to 45° is a special triangle that has both leg lengths of the triangle equal
Therefore;
The length of the other leg of the right triangle = n = The length of the given leg of the triangle = (9·√2)/2
∴ n = (9·√2)/2
n = (e·√f)/g
Therefore, by comparison, we have;
e = 9, f = 2, and g = 2
By Pythagoras's theorem, we have;
m = √(n² + ((9×√2)/2)² = √((9×√2)/2)² + ((9×√2)/2)²) = √(81/2 + 81/2) = √81 = 9
m = 9.
Mateo started with more
than 100 boxes of cookies to
sell He sold 25 boxes. After
selling 25 boxes, how many
more boxes can he sell to
sell them all?
Answer:
y > 75
Step-by-step explanation:
Given that:
Starting number of boxes = > 100
Number of boxes sold = 25
Number of boxes left after selling 25
Let the number of boxes left = y
y = starting number of boxes - Numbe rof boxes sold
y = 100 - 25
y = 75
Since the starting number of boxes is more than 100
Then, y should also be more than 75
y > 75
