Answer:
In order to get equivalent ratios, we can just multiply by a factor! Lets use the factors of 2, 3, 4.
So we have:
[tex]2 * \frac{6}{9}=\frac{2*6}{2*9}=\frac{12}{18}[/tex]
As well as:
[tex]3 * \frac{6}{9}=\frac{3*6}{3*9}=\frac{18}{27}[/tex]
And finally:
[tex]4 * \frac{6}{9}=\frac{4*6}{4*9}=\frac{24}{36}[/tex]

Which equation represents a linear function?
Answer:
Y=2x-6
Step-by-step explanation:
Linear equation in two variables represents a line.
What is the solution to the system of equations graphed below
Y=2x-7 y=-x-1
The value of the common solution to the system of equation is (2,-3).
What is System of Equation?The system of equation is set of equations which have a common solution.
The figure shows the graph of two equations, these equations are a straight line function and the common solution is represented by a point in the image.
The solution of the system of equation can be obtained both by solving using substitution method and even by plotting the graph and finding the intersection point.
The system of equation is,
y = 2x - 7
y = -x -1
The value of y from equation 2 will be substituted in equation 1
-x -1 = 2x -7
3x = 6
x = 2
Substituting this value in equation 2
y = -2 -1
y = -3
The value of (x,y) is (2,-3)
The graph is plotted and the intersection of the line is at (2,-3)

If the surface area of a cylinder is 800 in^2 and the height is 15 in, what is the base?
Answer:
base = diameter
Step-by-step explanation:
if the surface area of the cylinder is 800...
the height is 15... then the formula must be 3.14 x 15 x R2
r squared is supposed to be the square of the radius of the cylinder\
conclusion: 3.14 x 15 x R2 is 800_
so.multiply then..find the radius and add the answer you get to find the diameter ..What are the values of x, y, and z in this system of equations?
2x+4y+z=1
x-2y-3z=2
x+y-z=-1
Answer:
{x,y,z}={5,−3,3}
Step-by-step explanation:
[1] 2x + 4y + z = 1
[2] x - 2y - 3z = 2
[3] x + y - z = -1
// Solve equation [3] for the variable y
[3] y = -x + z - 1
// Plug this in for variable y in equation [1]
[1] 2x + 4•(-x +z -1) + z = 1
[1] -2x + 5z = 5
// Plug this in for variable y in equation [2]
[2] x - 2•(-x +z -1) - 3z = 2
[2] 3x - 5z = 0
// Solve equation [2] for the variable x
[2] 3x = 5z
[2] x = 5z/3
// Plug this in for variable x in equation [1]
[1] -2•(5z/3) + 5z = 5
[1] 5z/3 = 5
[1] 5z = 15
// Solve equation [1] for the variable z
[1] 5z = 15
[1] z = 3
// By now we know this much :
x = 5z/3
y = -x+z-1
z = 3
// Use the z value to solve for x
x = (5/3)(3) = 5
// Use the x and z values to solve for y
y = -(5)+(3)-1 = -3
Solution :
{x,y,z} = {5,-3,3}
records shows that 3 out of 4 families move about every 6 years. what is the percentage of families that move every 6 years?
75%.
3 out of 4 means 3/4
And if you divide 3/4 the answer is .75
So multiply by 100( because to convert decimal to percent you have to multiply by 100, or move the decimal place two places to the right) and you get 75
Slap a percent sign on there and you have 75%

AM = 5x - 2 and MB = 2x + 19, Find the length of AB
Answer:
The answer would be: -0.01
Step-by-step explanation:
1) State what is given
AM = 5x -2 and MB = 2x +19
2) Make an equation that can satisfy the problem
AM + BM = AB
This is the equation, because if I am to put this on a line,
A M B
-_____________-_____________-
You can see that is you combine the lengths AM and BM you can find the total length of AB.
A M + M B
-_____________- + -_____________-
(M point is actually one point, but I am trying to show that if the line were to be cut in half, then put back together you get you full length, which is AB)
3) Substitute
(5x - 2) + (2x + 19) = AB
4) Now Solve!
5x - 2 + 2x + 19 = AB
(Rearrange to combine like terms)
5x + 2x + 19 - 2 = AB
7x + 17 = AB
(That is your equation to find AB! But they want the specific length)
So...
We solve it!
7x = -17
(By moving the 17 to the other side of the = sign, it becomes negative)
7x = -17
7 7
(Dividing both sides by 7 in order to get x alone)
x = -2.43
(I rounded to the hundredths place)
Now substitute that into x into you original equation)
5(-2.43) - 2 + 2(-2.43) + 19 = AB
-12.15 - 2 - 4.86 + 19 = AB
-14.15 - 4.86 + 19
-19.01 + 19 = -0.01
= -0.01
(I believe this would be the answer, but it doesn't seem to fit right, so please understand, that if this is wrong, I AM SO SORRY ;-;)
(I tried my best on this problem, but I bet it isn't the answer, so if I get this wrong tell me so that I can remove it! :)

A car dealership needs to transport 58 cars to a new lot. If the transport truck can haul 6 cars at a time, how many trips will the transport truck need to make?
Answer:
10
Step-by-step explanation:
We need to find how many trips it will take to transport 58 cars
The explanation is simple:
58 / 6 = 9.6 repeating
So we round that quotient up to 10.
So the transport truck will need to take 10 trips to transport all 58 cars.

Jonathan forgot his math homework on the kitchen table and left for school without it. He biked at the speed of 15 mph. His mother saw the homework when he was already 1 mile from home, and started chasing him. She drove at a speed of 25 mph and caught him at the school entrance. How far is the school from Jonathan's home?
Answer:
2.5 miles
Step-by-step explanation:
We know that: time = distance/speed
Now, if the distance of the school from Jonathan's home is y.
At speed of 15 mph, Jonathans time is; time = y/15 hours
At 25 mph, his mother's time was;
time = y/25 hours
We are told that Jonathan was 1 mile from home when he saw his mother.
Thus means that difference in time is;
Time difference = 1/15 hours
Thus;
y/15 hours - y/25 hours = 1/15 hours
Multiply through by 75 to get;
5y - 3y = 5
2y = 5
y = 5/2
y = 2.5 miles

A board 60 in long is cut into two parts so that the longer piece is 5 times the shorter. What are the two lengths of the two pieces ?
The shorter piece is _____ a° in
the longer piece is _____a° in
Answer:
Longer piece: 50 in
Shorter piece: 10 in
Step-by-step explanation:
Lets make the shorter piece = x
Leta make the longer piece = 5x
Since the longer piece is 5 times the shorter, this is why we put 5x, because 5 times the shorter. We also have to find the two lengths of the pieces which in total equals 60 in.
x + 5x = 60 in
If we substitute the x to 10:
10 + 50 = 60 in
10 in = shorter length
50 in = longer length

Answer:
17x^2 -5x
Step-by-step explanation:
"Simplify" in this context means "combine like terms." It can help to group the terms with the same variables.
-9x+9x^2+8x^2+4x
= 9x^2 +8x^2 -9x +4x
= x^2(9+8) +x(-9+4)
= 17x^2 -5x
Which statements correctly describe the graph of the function f(x) = x3 – 4x2 – 3x + 18? Select three options. There are three unique solutions to the function when y=0. The function has a double root. As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again. As x approaches negative infinity, y approaches positive infinity. The domain and range of the function are the set of real numbers.
Answer:
The function is:
f(x) = x^3 - 4*x^2 - 3*x + 18.
Below, you can see the graph of the function.
The statements that are true are:
As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.
You can see this in the graph and may be really hard to see it without the graph, the easier way would be to see the derivate of f(x) and see that is first positive, then negative, and then positive.
f'(x) = 3*x^2 - 8*x - 3
As the leading coefficient is positive, the arms oppen up, and f'(0) = -3
Then is easy to see that from left to right, is positive, then negative, and then positive again.
The domain and range of the function are the set of real numbers.
For the domain, we do not have any denominator nor weird function that has problems in a particular value, so the domain is the set of all real numbers.
And as you can see, as the leading coefficient is an odd power of x, the range will go from minus infinity to infinity (you can also see it in the graph).
The function has a double root.
Yes, in the graph you can see two roots, but this is a 3rd-degree polynomial, so it must have 3 roots, this means that one of the roots in the graph is a double root. (Where the double root is at x = 3, as you can see in the graph)
