Answer:
6 sqrt(3) = y
Step-by-step explanation:
We can use the leg rule to find y
hyp leg
----- = -------
leg part
9+3 y
----- = -------
y 9
Using cross products
12*9 = y^2
108 = y^2
Taking the square root of each side
sqrt(108) = sqrt(y^2)
sqrt(36 *3) = y
6 sqrt(3) = y
Answer:
12
Step-by-step explanation:
Answer:
The answer to your question is x = -22; y = 4
Step-by-step explanation:
System of equations
2x + 5y = -24 ------------- l
3x - 5y = 14 ------------- ll
Process
1.- Multiply equation l equation l by 3 and equation ll by -2
6x + 15y = -72
-6x + 10y = -28 Add the equations
0 + 25y = 100
2.- Solve for y
y = 100/25
y = 4
3.- Substitute y in equation l to find x
2x + 5(4) = -24
Solve for x
2x + 20 = -24
2x = -24 - 20
2x = -44
x = -44/2
x = -22
