Step-by-step explanation: this is only if you can use the same number twice!!!
Answer:
y = 1
Step-by-step explanation:
Find the slope of the line passing through the points
and ![(7,y):](https://tex.z-dn.net/?f=%287%2Cy%29%3A)
![m=\dfrac{y-3}{7-2}=\dfrac{y-3}{5}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By-3%7D%7B7-2%7D%3D%5Cdfrac%7By-3%7D%7B5%7D)
The slope of the line is equal to
![m=-\dfrac{2}{5},](https://tex.z-dn.net/?f=m%3D-%5Cdfrac%7B2%7D%7B5%7D%2C)
then
![\dfrac{y-3}{5}=-\dfrac{2}{5}\\ \\y-3=-2\\ \\y=-2+3\\ \\y=1](https://tex.z-dn.net/?f=%5Cdfrac%7By-3%7D%7B5%7D%3D-%5Cdfrac%7B2%7D%7B5%7D%5C%5C%20%5C%5Cy-3%3D-2%5C%5C%20%5C%5Cy%3D-2%2B3%5C%5C%20%5C%5Cy%3D1)
Answer:
a = 7.4
b = 9.6
Step-by-step explanation:
set up a proportion to find 'b':
XN / NY = MN / NO
8/b = 13/(b+6)
cross-multiply:
13b = 8(b+6)
13b = 8b + 48
5b = 48
b = 9.6
set up a proportion to find 'a':
XN / XY = MN / MO
8/a = 13/12
cross-multiply:
13a = 96
a ≈ 7.4
