13. the equation of line l is given as y = 0.6x – 4.
if the slope is equal to a, y-intercept is equal
to b and x-intercept is equal to c, what is the
value of a + b + 3c?

16.6

Step-by-step explanation:

a = slope = 0.6

b = y-intercept = -4

c = x intercept = 20/3. (Set y=0 and solve for x)

So, a+b+3c = 0.6 - 4 + 3*20/3 = 16.6

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
