so first take two sets of coordinates. Find the slope using the slope formula; m=(Y₂-Y₁)/(X₂-X₁). Plug in the x and y values. let's use (14,21) and (2,3). Our equation would be (3-21)/(2-14)=(-18)/(-12)=1.5. Then use point-slope form; (Y-Y₁)=m(X-X₁). Plug in the x and y values, and get (y-21)=1.5(x-14). Simplify and get y-21=1.5x-21. Add 21 on both sides, and you get your final equation y=1.5x. So equation 1 will match A. Then do those same steps for the rest of the equations.

When you flip an object by the x axis, the x part of the coordinates (x, y) would become negative, or if already negative, positive. Try it yourself, by taking point be, and counting down to the line of the x axis. Remember the number down you counted, and count that same number down from the x axis. That is mirroring a point.

Step-by-step explanation:
If the big side is double the small side, then the math is simple. You just find 2/3 of each side. The big side would be 300 because it is double the small side, which is already stated as 150.

Step-by-step explanation:
Are the two expressions equivalent when x=6?
4(3x+x)
12x
Answer: No.
Step-by-step explanation:
We are already given the value of x, so all we have to do is substitute the value of x into the expressions.
For the first expression :
1. Substitute the value of x (in this case the value of x is 6) into the expression. Like this: 4(3(6)+6)
We need to put the 6 next to the 3 into a parenthesis because an x next to a number means 3 times the value of x. The parenthesis symbolizes multiplication. So, 3x is the same as 3(6).
2. Solve the parenthesis "3(6)". All we would have to do is multiply 3x6. 3x6 = 24. Now the expression looks like this: 4(24+6)
3. Solve the parenthesis. All we have to do is multiply 4x24 and 4x6. We know 4x24 = 96. And, 4x6 = 24. So, we just fill that in. It will look like this: 96+24
4. Add it up. 96+24 is 120. So, the first expression equals 120.
For the second expression :
The second expression is simple. As I said before, a number next to x means x multiplied by that number, just like parenthesis. So, we would substitute the x to 6 and put that in parenthesis. Like so: 12(6).
Now, just multiply that. 12x6=72. So, the second equation is equivalent to 72.
Summary:
The first expression is equivalent to 120. The second expression is equivalent to 72. These two numbers are not equivalent. So, the expressions are not equivalent when x=6.
How the solving process would look for the first expression :
4(3x+x)
4(3(6)+x)
4(24+6)
96+24
120
How the solving process would look for the second expression :
12x
12(6)
72
A hyena can run one over four of a mile in 22.5 seconds. At this rate, which equation can be used to determine how fast a hyena runs in miles per hour? (5 points)
one-fourth mile over twenty-two point five seconds = 40 miles per hour
twenty-two point five seconds over one-fourth mile = 40 miles per hour
one-fourth mile over twenty-two point five seconds = 90 miles per hour
twenty-two point five seconds over one-fourth mile = 90 miles per hour
I basically just need to know which equation it is. I know its 40 miles per hour.
Answer:
1/4 mile over 22.5 seconds.
Step-by-step explanation:
Because you are calculating miles over hours, not hours over miles, miles will be on top and hours will be on bottom. Hope this helps!

Find the missing dimension of the cylinder. Round your answer to the nearest whole number.
Volume = 3785 cm3
Answer:
8 cm
Step-by-step explanation:
volume of a cylinder is v=pi x r^2 x h
substitute in what we know
3785= pi x r^2 x 19
3785=59.69 x r^2
subtract 59.69 from both sides
3725.31=r^2
square root of 3725.31

square root of 61

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
A The expressions are only equivalent for x = 4 and x = 6.
B The expressions are only equivalent when evaluated with even values.
C The expressions have equivalent values for any value of x.
D The expressions should have been evaluated with one odd value and one even value.
E When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
F The expressions have equivalent values if x = 8.
Answer:
7x + 4 = 3x + 5 + 4x - 1
7x + 4 = 7x + 4
C. The expressions have equivalent values for any value of x.
A bucket of sand weighed 3 pounds. Then Eloise added another 20 ounces of sand to the bucket.
How much does the bucket of sand weigh now?
4 1/ 4 lb
4 1/2 lb
5 1/4 lb
5 1/2 lb
The weight of the bucket of sand after Eloise added 20 ounces of sand is 4.25 pounds
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we need to convert 20 ounces to pounds.
There are 16 ounces in 1 pound, so 20 ounces is equal to:
20/16 = 5/4 = 1.25 pounds
Therefore, the weight of the bucket of sand after Eloise added 20 ounces of sand is:
3 + 1.25 = 4.25 pounds
Thus,
The weight of the bucket of sand after Eloise added 20 ounces of sand is 4.25 pounds

After arguing for two weeks, Nora convinced her parents to have her birthday party at FlyZone trampoline park. As soon as she gets there, Nora spends time practicing flips on the trampolines. Then, she spends 1/2 of an hour eating birthday cake with her friends. In all, Nora spends 1 3/4 hours at FlyZone. Which equation can you use to find the amount of time Nora practices flips?
Solve this equation for (t) to find the amount of time Nora practices flips
To write a fraction.
Answer:
t = 1 1/4 hours
Step-by-step explanation:
Lets first make an equation to represent the situation. t + 1/2 = 1 3/4
Because we cant add fractions with different denominators we have to change 1/2 to 2/4.
Next, we need to isolate t. Subtract 2/4 from both sides of the equation to get 1 1/4.
t = 1 1/4.
In your indoor garden, 50% of seeds sprout. What is the experimental probability that at least one of your next three seeds sprout?
Using the binomial distribution, it is found that there is a 0.875 = 87.5% probability that at least one of your next three seeds sprout.
For each seed, there are only two possible outcomes, either it sprouts, or it does not. The probability of a seed sprouting is independent of any other seed, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
50% of seeds sprout, hence p = 0.5.There are 3 seeds, hence n = 3.The probability that at least one of your next three seeds sprouts is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125[/tex]
Then:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.125 = 0.875[/tex]
0.875 = 87.5% probability that at least one of your next three seeds sprout.
