Answer:
30 Degress
Step-by-step explanation:
3 is a common multiple .. (3x4=12....3x5=15)
2x+y=-4
5x+3y=-6
multiply first equaton by -5 and second by 2 then add them
-10x-5y=20
<u>10x+6y=-12 +</u>
0x+1y=8
y=8
the y value is 8
Answer:
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
Step-by-step explanation:
Parallel lines have same slopes.
Line 1, L1: 5x-2y=20 is in standard form Ax+By=C therefore slope m1= -A/B = -5/-2 = 5/2 or you can solve it for y so you will have the equation in slope-intercept form.
5x-2y = 20
-2y = -5x+20
y = (-5/-2)x+20/(-2)
y = (5/2)x-10 hence m1=5/2 and y-intercept is -10
Line 2 , L2: y-y1 = m (x-x1), m=m2=m1=5/2
Point p(5,0) or p(x1,y1) therefore x1=5 , y1=0 and m=5/2
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
If you're doing probabilities, there is a 1:6 chance on both (im guessing dont trust me i did probabilities a long time ago)
