Answer:
x = -11
Step-by-step explanation:
Answer:
y = x+1
Step-by-step explanation:
points (0,1) and (2,3)
slope =(y2-y1)/(x2-x1)
m = (3-1)/(2-0)
= (2/2)
m=1
the y intercept ( or where it crosses the y axis) is 1
y = mx+b
y = 1x+1
y = x+1

Step-by-step explanation:
First off, this wouldn't make sense for a girl to be older than her mother or her father.
Second, mother is x years old. The girl is 2x years old. The father is x+5 years old. Total sum = 100.
So, we need to solve for x first.
2x + x + x+5 = 100
4x + 5 = 100
4x = 95
4x ÷ 4 = 95 ÷ 4
x = 23.75
Mother is 23 and 3 quarters, turning 24.
Daughter is 23.75 × 2 = 47 1/2 years old.
And the Father is 28 and 3 quarters, turning 29.
