Answer:12
Step-by-step explanation:
4x - 10= 3x+2 add 10= 4x = 3x+12 subtract 3x=1x 1x=12 divide 12 by 1=12 should be 12 sorry if I got it wrong...
Answer:
We get value of y: y = 2
Step-by-step explanation:
The points (3,5) and (2, y) are on a line with a slope of 3. Find y.
We can find y using formula of finding slope of a line.
The formula is: ![Slope=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have
and Slope = 3
Putting values and finding y
![Slope=\frac{y_2-y_1}{x_2-x_1}\\3=\frac{y-5}{2-3}\\3=\frac{y-5}{-1}\\-1(3)=y-5\\-3=y-5\\y=-3+5\\y=2](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C3%3D%5Cfrac%7By-5%7D%7B2-3%7D%5C%5C3%3D%5Cfrac%7By-5%7D%7B-1%7D%5C%5C-1%283%29%3Dy-5%5C%5C-3%3Dy-5%5C%5Cy%3D-3%2B5%5C%5Cy%3D2)
So, we get value of y: y = 2
N=25 because 20 divided by 4 is 5 which is 1/5 of n meaning 5x5 is 25
