Which table does NOT show direct variation?
Answer:
Tables 3. The one in the bottom left corner.
Step-by-step explanation:
The values of table C is not in variation.
What is variation?Two sorts of quantities typically exist in a mathematical equation when a relationship is established for a certain type of parameter. One is a constant that stays the same regardless of how the other variables in the equation vary, and the other is a variable that changes depending on the circumstances. Variation is the term used to describe the changing of variables.
Given tables,
A direct variation is a straightforward relationship between x and y. To find a direct relationship, either use the formula y = kx or divide y over x (y/x).
Relation for table A
y /x = -3/1 = -3
y /x = -9/3 = -3
y /x = -18/6 = -3
y /x = -36/12 = -3
relation is in variation.
Relation for table B
y /x = 3/1 = 3
y /x = 9/3 = 3
y /x = 18/6 = 3
y /x = 36/12 = 3
relation is in variation.
Relation for table C
y /x = 4/1 = 4
y /x = 6/3 = 2
y /x = 9/6 = 3/2
y /x = 15/12 = 5/3
Equation doesn't have a direct relationship between x and y.
Relation for table D
y /x = 2/1 =2
y /x = 6/3 = 2
y /x = 12/6 = 2
y /x = 24/12 = 2
relation is in variation.
Hence the table C is not in variation.

Can someone show me the steps to solve this I will give u a Brainly crown (10points)
(Will get reported if you comment something wrong)
Answer:
Step-by-step explanation:
1/4a + 1/3a + 8 = 22
Collect like terms
1/4a + 1/3a = 22 - 8
Simplify
3a+4a/12 = 14
7/12a = 14
Divide both sides by 7/12
a = 14 ÷ 7/12
= 14 × 12/7
= 168/7
= 24
a = 24
Check:
1/4a + 1/3a + 8 = 22
1/4(24) + 1/3(24) + 8 = 22
24/4 + 24/3 + 8 = 22
6 + 8 + 8 = 22
22 = 22

What is the quotient of 3/4 divided by 1/5?
The quotient is
3 and ___________
Answer:
The quotient is 3 and [tex]\frac{3}{4}[/tex].
Step-by-step explanation:
To find the quotient of the division (which is just the solution, really), we have to solve the division itself:
[tex]\frac{\frac{3}{4}}{\frac{1}{5}}[/tex]
[tex]= \frac{3 \cdot 5}{1 \cdot 4}[/tex]
[tex]= \frac{15}{4}[/tex]
Now that we know the quotient, we can look at the question itself to find it requires from us an answer with a whole number in it.
Therefore, we transform the fraction as thus:
[tex]\frac{15}{4}[/tex]
[tex]= 3 \frac{3}{4}[/tex]
Therefore, the final answer is 3 and [tex]\frac{3}{4}[/tex].

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y < 4x − 2
y is greater than or equal to negative 5 over 2 times x minus 2
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (−2, −2) included in the solution area for the system? Justify your answer mathematically. (4 points)
(10 points)
if you abuse the amount of points I put on this question I will report you
Answer:
Photo.
Step-by-step explanation:
A: The graph of the system is all points in the graph that suit 4x-2<y</=-5/2x-2
B: The point (-2,-2) is not included in the solution area. While it suits the second equation, it doesn't suit the first, ruling it out as a possible solution. If you plug in -2 as both y and x in the equation 4x-2>y, you'll get -8>-2, which is false. So, it is not a solution.

How do I solve this equation by completing the square. X^2 - 12x = -20
Answer:
I got x=2
Step-by-step explanation:
1. Simplify the quadratic equation into its standard form

Ax^2 +Bxc=0
Simplify the equation by subtracting everything to the right of the equal sign from both sides of the equation and combining like terms.
x^2-12x+0=-20
x^2-12x+0+20=0
x^2-12x+20=0
The Quadratic formula provides the solution for Ax^2 +Bxc=0, in which A, B, and C are numbers (or coefficients), as follows:
The coefficients of our equation, x^2-12x+20=0, are:
A = 1
B = -12
C = 20

Answer:
Step-by-step explanation:
What I can see from this are many things. First of all, the girls achieved a higher score than the boys since the girls got a higher mean then the boys. This means that if we were to take the average score of each gender, the girls got a higher score. To find the average/mean you need to find the sum of the data set then divide it with the number of data entries. The boys had a smaller range than the girls, which means that the scores the boys achieved were closer than the girls. The higher the range the more likely your data is scattered. The lower your range, the more likely your data is contained of similar numbers. You figure out the range but subtracting your highest data point from your lowest data point.
what is the slope of the graph
Answer:
- 5/3
Step-by-step explanation:
Line is passing through the points (0, 2) & (3, - 3)
Slope of the graph = (- 3 - 2)/(3 - 0) = - 5/3
Solve the system of equations by elimination.
2x - y + 3z=-1
x + 2y - 4z=-1
y – 2z=0
Answer:
x = -1, y = 2 and z = 1
Step-by-step explanation:
The given system of equations are :
2x - y + 3z= -1 ....(1)
x + 2y - 4z = -1 ......(2)
y – 2z = 0 .....(3)
Equation (3) can be written as :
y = 2z
Use y = 2z in equation (2)
x + 2(2z) - 4z = -1
x + 4z - 4z = -1
x = -1
Put the value of x in equation (1) :
-2 -y +3z = -1
-y+3z = 1 ....(4)
Adding equation (3) and (4)
y-2z+(-y+3z)=1
z = 1
Now put z = 1 in equation (4)
-y+3=1
-y = -2
y = 2
Hence, the values of x,y and z are -1, 2 and 1 respectively.
