The picture is my question please don't lie or I will report your question
Answer:
Third option.
Step-by-step explanation:
This is matrix addition, so we have to add the corresponding parts of the matrix correctly. The first would be 12+(-3), getting 9. The second part would be (-5)+(-9), getting up -14. Third would be 0+(-14), getting -14. Last would be (-7)+10, getting 3. So, the option with all of the correct parts in their respective positions would have to be the third option.
Hope this helped!

Complete the explanation of how you can identify a linear non-proportional relationship from a table, a graph, and an equation.
In a table, the ratios (y,x) over (x,y) will not be equal, and the rates of change
(will not, will )be equal The graph will be a line that (does not pass, passes ) through the origin. An equation will be in the form y= mx +b , where b (is no equal to, equals) 0.
Here is the completed explanation:
In a table, the ratios (y,x) over (x,y) will not be equal, and the rates of change will not be equal. The graph will be a line that does not pass through the origin. An equation will be in the form y= mx +b , where b is not equal to 0.
In a table:
For a non-proportional linear relationship, as x increases by a certain amount, y will increase by a different amount.
The ratios (y increase, x increase) and (x increase, y increase) will not be equal.
The rate of change of y with respect to x will not be constant.
In a graph:
The line will not pass through the origin (0,0). If it did, the relationship would be proportional.
In an equation:
The equation will be of the form y = mx + b, where b is not equal to 0.
If b was equal to 0, the line would pass through the origin, indicating a proportional relationship.
So in summary, to identify a non-proportional linear relationship from a table, graph, or equation, look for:
Unequal ratios of change in x and y
Unequal rates of change
A line graph that does not pass through the origin
An equation of the form y = mx + b, where b is not equal to 0.
Which value does not represent the probability of an event?

A. x = 7
B. x = -3
C. x = 0
D. x = 2
E. x = 3
F. x = -1
2x + 1 > 5
2x > 5 - 1
2x > 4
x > 4 ÷ 2
x > 2
answer is E since x = 3 is larger than 2.

The graph shows how the volume of a gas sample changes as the temperature changes and the pressure remains constant. What is the rate of change of the volume of the gas sample with respect to the temperature?
Answer:
Assumming the y intercept is at 0,20, the slope is [tex]\frac{1}{3}[/tex]
Step-by-step explanation: [tex]\frac{36-26}{50-20}[/tex] = [tex]\frac{10}{30}[/tex] = [tex]\frac{1}{3}[/tex]
Using the slope formula the rate of change of the volume of the gas sample with respect to the temperature is [tex]\frac{1}{3}[/tex].
What is the slope?A rising or falling surface is one that has one end or side that is higher than the other.
It is given that from the graph, the given line passes through the points (20,26) and (50,36).
Knows the slope of the line which passes through the points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex].
Therefore, the rate of change of the volume of the gas sample with respect to the temperature
[tex]& \Rightarrow \text{Slope}=\frac{36-26}{50-20} \\ & \Rightarrow \text{Slope}=\frac{10}{30} \\ & \Rightarrow \text{Slope}=\frac{1}{3} \\[/tex]
Therefore, using the slope formula the rate of change of the volume of the gas sample with respect to the temperature is [tex]\frac{1}{3}[/tex].

The volume of the rectangular prism is 60 cm3. What is the length of the missing side?
Haley solved the problem. Her work is shown below. Is she correct or incorrect and why?
The length of the missing side is 10 cm.
What is the volume of the rectangular prism?The volume of a rectangular prism is the measurement of the total space inside it.
The volume of a rectangular prism is given by;
[tex]\rm Volume \ of \ rectangular \ prism =Length \times Width \times Height\\\\[/tex]
The volume of the rectangular prism is 60 cm^3.
The volume of a rectangular prism is;
[tex]\rm Volume \ of \ rectangular \ prism =Length \times Width \times Height\\\\ 60=Length \times 2\times 3\\\\60 = 6 \times length \\\\Length =\dfrac{60}{6}\\\\Length =10[/tex]
Hence, the length of the missing side is 10 cm.
