How do i graph this equation . any steps ?

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

i believe that the answer is

b. y-1=-2(x-4)

hope this !

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
