Answer:
x,y =2,1
Step-by-step explanation:
3x+4y=10 ................equ1
x-y=1 ................equ2
This system of equations forms a quadratic equation.
Lets use the substitution method in solving this set of equations
from equ 2; x=y+1
substitute x=y+1 into equ 1
3(y+1) +4y=10
3y+3+4y=10
7y=10-3
7y=7
y=7/7
y=1
but x=y+1
substitute the value of y into this equation to get x
x= 1+1
x=2
x,y=2,1
To solve this, we just have to subtract the numbers.
That's our solution set.
Have a nice day! :)
Answer:
See below.
Step-by-step explanation:
The area = length of the base * perpendicular height.
If you are given the lengths of the side and the measure of one of the angles you can use the trigonometry to find the perpendicular height.
