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
81.6 is the correct answer
Answer:
C
Step-by-step explanation:
Keep a consistent ratio of 4:2, and we need a total of 36 glasses of punch.
So if the ratio 4:2 is a total of 6, then we would need 6 times the amount because 6*6 is 36. So 4 and 2 * 6 or 6 (4+2) = 24+12. So the answer is C.
Hope this helps in some way.
