Answer:
x=4
Step-by-step explanation:
well you know that the square is 90 degrees so you set it up as 90=21x+6. Then you subtract 6 from both sides and it gets you 84=21x. Then divide 21 on both sides. So the answer is x=4

There are 90 males and 75 females that came to Jeff's house for a party. Jeff wants to split the males into equal groups and the females into equal groups to play a game. The groups of males and females must have the same amount of people. What is the greatest number of people that can be in each group?
Answers
Answer:
15 people
Step-by-step explanation:
We are told that there are 90 males and 75 females.
This question is a greatest common factor question.
We find the factors of 75 and 90
The factors of 75 are: 1, 3, 5, 15, 25, 75
The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Then the greatest common factor is 15.
The greatest number of people that can be in each group is 15

Find the slope of the line that contains the points:(-6, 3) and (-4,5).
Answers
Answer:
Slope:1
Step-by-step explanation:
When finding the slope from 2 points, you subtract them y/x
(-6,3)
(-4,5)
-2,-2
Slope: (-2,-2)=1
y=x+b
Insert on of the the points, in this case, I will choose -6,3
3=-6+b
b=9
So slope intercept form, the answer will be y=x+9.
Since you are just finding the slope, the answer is just 1.
The slope of the line that contains the points:(-6, 3) and (-4,5) is 1.
What is the slope of the line?You could be asked to determine a line's slope when working with linear equations. Knowing the slope formula in that situation is really helpful. Watch this lesson to learn the formula for calculating the slope of a line.
Given the coordinate of the line (-6, 3) and (-4,5).
Hence from the formula of the slope (m) = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
m = (5 - 3) / (-4 + 6)
m = 1
Therefore the slope of the line that contains the given points is 1.

There are 4 quarters in 1 dollar the total number of dollars is a function of the number of quarters does this situation represent a linear or nonlinear function? Explain why
Answers
Answer:
sample answer: If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4
Step-by-step explanation:
The situation is a representation of the linear function.
What is meant by linear function?A linear function is one that, when graphed, produces a straight line. Thus, non-linear functions are any non-linear functions. Although graphing is the quickest way to determine whether a function is linear or non-linear, we can also determine linearity from its input/output table or equation. A straight line on the coordinate plane is represented by a linear function. For example, y = 3x - 2 denotes a straight line on a coordinate plane and, as such, a linear function.Given that,
One dollar is divided into four quarters.
The total number of dollars is a function of the number of quarters.
Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value
As a result, the slope should be 1/4.
y = 1/4x should be the linear function.
Hence, As a result, we can conclude that the situation is a linear function.

x-7(x-2)=10x+9-x
i need the answer asap pls
Answers
Step-by-step explanation:
x−7(x−2)=10x+9−x
Step 1: Simplify both sides of the equation.
x−7(x−2)=10x+9−x
x+(−7)(x)+(−7)(−2)=10x+9+−x(Distribute)
x+−7x+14=10x+9+−x
(x+−7x)+(14)=(10x+−x)+(9)(Combine Like Terms)
−6x+14=9x+9
−6x+14=9x+9
Step 2: Subtract 9x from both sides.
−6x+14−9x=9x+9−9x
−15x+14=9
Step 3: Subtract 14 from both sides.
−15x+14−14=9−14
−15x=−5
Step 4: Divide both sides by -15.
−15x−15=−5−15
