<u>Answer:</u>
It's X=2
<u>Working out:</u>
<u>(left one):</u>
2(x+3)=10
2x+6=10
2x=10-6
2x=4
x=2
Working out:
(right one):
2(x+3) must be all divided by 2 so it will be x+3 and same for 10, it will be 5 so...
x+3=5
x=5-3
x=2
Hope it helps ^---^
Table B of course they follow by the order instead of table A
Answer:
27
Step-by-step explanation:
cuz 29 - 4 - 2 = 27
The formula of linear equation is:
![y1 - y2 = m(x1 - x2)](https://tex.z-dn.net/?f=y1%20%20-%20%20y2%20%3D%20m%28x1%20%20-%20%20x2%29)
Where
x1 and x2: x coordinates(-1 and 3)
y1 and y2: y coordinates(-2 and 10)
m is the slope
We can then choose a point from the line to find the eqaution.
We need to first find the slope:
![\frac{y1 - y2}{x1 - x2}](https://tex.z-dn.net/?f=%20%5Cfrac%7By1%20-%20y2%7D%7Bx1%20-%20x2%7D%20)
In this case:
![\frac{ - 2 - 10}{ - 1 - 3} \\ = \frac{ - 12}{ - 4} \\ = 3](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%202%20-%2010%7D%7B%20-%201%20-%203%7D%20%20%20%5C%5C%20%3D%20%20%5Cfrac%7B%20-%2012%7D%7B%20-%204%7D%20%20%5C%5C%20%20%3D%203)
In this case, as the y2 is given as 1,put (-1,-2) , and the slope(3 )into the eqaution :
y-(-2) = 3(x-(-1))
y+2 = 3(x+1)
Therefore
![y + 2 = 3x + 1](https://tex.z-dn.net/?f=y%20%2B%202%20%3D%203x%20%2B%201)
is the answer.
Hope it helps!
Answer:
10
Step-by-step explanation:
because 40 can go into 400 ten times
also if you do it on long division you will do 10 times 40 is 400
