Rewrite 20 − 4x3 using a common factor.
Using a common factor, 20 - 4x³ can be rewritten as 4(5 - x³).
What is a Common Factor?A common factor of two or more numbers is any number that the two numbers can be divided by and will leave no remainder.
For example, a common factor of 4 and 8 is 2. This is because:
2 into 4 will give us 2 without a remainder.
2 into 8 will give us 4 without a remainder.
To rewrite the expression, 20 - 4x³ using a common factor, find the factor that will go into each of the terms without a remainder.
4 into 20 will give us 5 without a remainder.
4 into 4x³ will give us x³ without a remainder.
Therefore, we can factor out the common factor from the expression to rewrite 20 - 4x³ as 4(5 - x³).

The system of equations is:
[tex]\begin{gathered} 6x+3y=12 \\ 8x+4y=24 \end{gathered}[/tex]To solve the system of equations by graphing, we need to make a graph of each equation. For that, we solve for y in both equations:
[tex]\begin{gathered} \text{Solving the first equation for y:} \\ 6x+3y=12 \\ 3x=-6x+12 \\ y=-2x+4 \\ \text{Solving the second equation for y:} \\ 8x+4y=24 \\ 4y=-8x+24 \\ y=-2x+6 \end{gathered}[/tex]We have two equations to graph:
[tex]\begin{gathered} y=-2x+4 \\ y=-2x+6 \end{gathered}[/tex]Comparing with the slope-intercept equation:
[tex]y=mx+b[/tex]Where m is the slope and b is the y-intercept.
We can see that the slope of the two equations is m=-2, this means that the lines will have the same rate of change of -2 in y for every 1 in x. And one graph will cross the y-axis at 4 and the other at +6.
The graph of the two equations is shown in the following image:
Where the green line is the first equation, and the red line is the second equation.
There is no solution to this system of equations because the lines do not intersect each other.

The possibility of the result of any random event is known as probability. This phrase refers to determining the likelihood that any given occurrence will occur. What are the chances of receiving a head, for instance, when we toss a coin in the air? The number of outcomes that could occur is the basis for the response to this question. The outcome in this case might be either head or tail. Therefore, there is a 50% chance that the result will be 1 / 2 head.

To avoid having to pay a claim for these tubes, we need to determine the likelihood that they will live longer than a year.
Given by: The likelihood of tubes lasting longer than a year is

What are square and square roots?A number can be squared, but it can also be divided into its square root. The value we get from multiplying a number by itself yields its square value, whereas the value we get from finding a number that, when squared, yields the original value of the number yields its square root value. In the event that 'a' is the square root of 'b,' then a a = b. Any number has two square roots, one with a positive value and the other with a negative value, because any number's square is always a positive number. As an illustration, the square root of 4 has the values 2 and -2. A number's power 1/2 value is represented by a number's square root. In other words.

The area of the trapezoid below is 24 square meters, the altitude is 4 meters, and the length of one base is 2 meters. What is the length, x, of the other base, in meters?
The length, [tex]x[/tex], of the other base, in meters is 10.
The area of trapezoid = 24 square meters
The altitude = 4 meters
The length of one base = 2 meters
We have to find the length [tex]x[/tex] of the other base in meters.
To find the value of the length [tex]x[/tex] we use formula of area of trapezoid.
We use the area of trapezoid to find the value of length [tex]x[/tex] because we know the value of area of trapezoid, length of one base and altitude.
As we know the formula of area of the trapezoid
[tex]A=\frac{a+b}{2}\times H[/tex]
In the formula,
[tex]A=[/tex] area of trapezoid
[tex]a[/tex] and [tex]b[/tex] are the two length of two different base of the trapezoid
[tex]H=[/tex] height or altitude of the trapezoid
From the given question, [tex]A[/tex] = 24 square meters, [tex]a=x[/tex] meter, [tex]b[/tex] = 2 meters and [tex]h[/tex] = 4 meters.
Now putting the values in the formula.
[tex]24=\frac{x+2}{2}\times 4[/tex]
[tex]24=(x+2)\times 2[/tex]
Divide by [tex]2[/tex] on both side
[tex]\frac{24}{2} =\frac{(x+2)\times 2}{2}[/tex]
[tex]12=x+2[/tex]
Subtract [tex]2[/tex] on both side
[tex]12-2=x+2-2[/tex]
[tex]10=x[/tex]
[tex]x=10[/tex]
Hence, the length, [tex]x[/tex], of the other base, in meters is 10.

The width of a rectangle is 3 units less than the length. The area of the rectangle is 18
units. What is the length, in units, of the rectangle?
Answer:
First let the length be a variable (eg: x) so that we can form an expression and solve.
Let the length of the rectangle be x units.
Form an expression for the width of the rectangle using the information given.
Width = (x - 3) units
Area of rectangle = length x width
Using the formula, form an equation.
x(x - 3) = 18
Simplify and solve for x.
x² - 3x = 18
x² - 3x - 18 = 0
(x - 6)(x + 3) = 0
x - 6 = 0 or x + 3 = 0
x = 6 or x = - 3 (reject)
The length cannot have a negative value so reject - 3.
Hence, the length of the rectangle is 6 units.

The ratio of the number of blue marbles to the number of marbles that are orange or green is 1 : 3.
Ratio is defined as the relationship between two quantities. It can be expressed as a to b, a/b, or a : b.
Let a = total number of blue marbles
b = total number of orange and green marbles
If the total number of blue marbles is 5 and the total number of orange and green marbles are 9 and 6, respectively, then the ratio is 5 to (9 + 6).

finding the slope
Answer:
slope = 50
Step-by-step explanation:
Equation of slope of line is
y = mx + b
where m = slope and b = y-intercept which is the y-value for the point at which the line crosses the y-axis
In the graph you can see that the line crosses at (0,0)
So y-intercept is 0
Equation is y = mx
To find m
take two points on the line and calculate rise/run
rise = difference in y-values
run = difference in x-values
Points(0,0) and 1, 50) lie on the line
rise = 50 - 0 = 50
run = 1-0 = 1
slope = 50 /1 = 50

Solve system of equation by substitution
7y=-2x+5
3x+10y=6
Answer:
x= -8/41
y= 27/41
Step-by-step explanation:
7y=2x+5
3x+10y=6
maybe divide all parts of first equation by 7 to leave y by itself: y=2/7x+5/7
Then plug that in for y in the second equation:
3x+10(2/7x+5/7)=6
Then just solve for x:
x= -8/41
Substitute value of x into first equation:
7y=2(-8/41)+5
Solve for y:
y=27/41
In systems of equations, the values of x and y are -8 and 3, respectively.
Given systems of equations are:
7y=-2x+5 .....(i)
3x+10y=6 .....(ii)
We want both equations to be in standard form (Ax + By = C) so we need to fix the first equation.
For the equation (i), simply add 2x from both sides, so that x & y are on the same side of the equal sign
2x + 7y = 5 .....(i)
3x + 10y = 6 .....(ii)
To get the same x value in both equations (i) and (ii), we must now multiply equation (i) by 3 and equation (ii) by 2.
3(2x + 7y = 5) .....(i)
2(3x + 10y = 6) .....(ii)
Simplify.
6x + 21y = 15 .....(i)
6x + 20y = 12 .....(ii)
Now, subtract equations (ii) from (i)
y = 3
Now, substitute value of y = 3 in equation (i).
2x + 7y = 5 .....(i)
2x + 7(3) = 5
2x + 21 = 5
Then, subtract 21 from both sides.
2x + 21 - 21 = 5 - 21
2x = - 16
Divide both sides by 2.
2x / 2 = - 16 / 2
x = -8
So, x = -8 & y = 3
