Kamil and Sean share some money in the ratio 3:5. Sean gets $56 more than Kamil. How much do they get each?
liq [111]
Let Kamil get x. Therefore Sean would get (x + 56).

Kamil and Sean are in the ratio:        3:5

That means:    x : (x + 56) = 3 : 5

x / (x + 56) = 3/5

5*x = 3*(x + 56)

5x = 3*x + 3*56

5x = 3x + 168

5x - 3x = 168

2x = 168

x = 168 / 2

x = 84

Therefore Kamil had, x = 84,  and Sean had (x + 56) = 84 + 56 =  140

Kamil had $84 and Sean had $140

In order to find the y-intercept, replace x by 0.

So, for first option:
f(0) = 7(1) - 2 = 5

For second option:
f(0) = -3(1) - 5 = -8

For third option:
f(0) = 5(1)-1=4

For Fourth option:
f(0) = -5(1) + 10 = 5

For Fifth Option:
f(0) = 2(1) + 5 = 7

So, option 1 and 4 have the y-intercept (0,5)
