You can sort them on the shapes that are the same or different
Answer:
b option im not sure but
Step-by-step explanation:
<em><u>Option B</u></em>
The result of addition is 2y = 24
<em><u>Solution:</u></em>
Given that we have to add the equations
<em><u>Given equations are:</u></em>
5x - y = -1
-5x + 3y = 25
We have to add both equations
This is similar to adding numbers. i,e 1 + 2 = 3
<em><u>For adding variables,</u></em>
When adding or subtracting terms that have exactly the same variables, you either add or subtract the coefficients, and let the result stand with the variable.
Example: 2x + 3x = 5x
Keeping this in mind, let us add the given equations
5x - y = -1
-5x + 3y = 25
----------------------------
0 + 2y = -1 + 25
[ 5x and -5x cancels each other. Combine -y and 3y which gives 2y]
2y = 24
Thus Option B is correct
Answer:
![q=10p](https://tex.z-dn.net/?f=q%3D10p)
Step-by-step explanation:
According to the given table, the variables have a linear relation, because there's a constant change involved.
Notice that p-variable increases by one unit, while q-variable increases by 10 units. That means the ratio of change is
![r=\frac{\Delta q}{\Delta p}=\frac{10}{1}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B%5CDelta%20q%7D%7B%5CDelta%20p%7D%3D%5Cfrac%7B10%7D%7B1%7D)
Then, we use one pair of elements, like (3,30), and the point-slope formula to find the equations.
![q-q_{1} =m(p-p_{1} )\\q-30=10(p-3)\\q=10p-30+30\\q=10p](https://tex.z-dn.net/?f=q-q_%7B1%7D%20%3Dm%28p-p_%7B1%7D%20%29%5C%5Cq-30%3D10%28p-3%29%5C%5Cq%3D10p-30%2B30%5C%5Cq%3D10p)
Therfore, the equation that represents the table is ![q=10p](https://tex.z-dn.net/?f=q%3D10p)
To the nearest tenth is 290 and to the nearest hundreth is 300
