-5x+2y=6
2y=6+5x
y=5/2x + 6
x+3y=3
3y=3-x
y=-x/3+1
-2x+y=4
y=2x+4
4x+9y=-9
9y=-4x-9
y=-4/9x+1
Hope this helps.
Answer:
x ≈ 44.69
Step-by-step explanation:
x² = 30² +21² -2(30)(21)Cos123°
x² = 900 + 411 - 1260cos123°
x² = 1311 - 1260cos123²
~Take square root of both sides
x = √1997.245184111
x ≈ 44.69
Best of Luck!
Im not sure if its y=19
y= 6(5)-11
y=30-11
y=19
