1)
I:y=3x-4
II:9x-3y=14
substitute y into II:
9x-3*(3x-4)=14
9x-9x+12=14
12=14
this is obviously not equal so there is no solution, the lines are parallel
2)
I:y=4x+6
II:5x-y=6
substitute y into II:
5x-(4x+6)=6
5x-4x-6=6
x=12
substiute x into II:
5*12-y=6
-y=6-60
-y=-54
y=54
the solution is (12,54)
Explaining- when you look at the vertex to the other vertex you see the length and that is when you multiply
Answer- A
Answer:
The answer is B) 72
Step-by-step explanation:
find the bigger arc: 360 - 108 = 252
x = 252 - 108/2
x = 144/2
x = 72
Y=0.5x-0.5
( u find the slope using rise/run then after finding the slope u use the equation and a point on the graph to find the y-intercept
The answer is 72 all u need to do plug in the numbers where the letters are
