Ben is 12 years older than Ishaan.Ben and Ishaan first met two years ago.Three years ago,Ben was 4 times as old as Ishaan.

djyliett [7]

Ben is 19 and Ishaan is 7.

If 3 years ago Ben was 4 times the age of Ishann, their ages could have been any of the following:

1. Ben is 4 and Ishaan is 1

2. Ben is 8 and Ishaan is 2

3. Ben is 12 and Ishaan is 3

4. Ben is 16 and Ishaan is 4

And so on.

Next add 3 to both ages, to show current age.

1. Ben is 7 and Ishaan is 4

2. Ben is 11 and Ishaan is 5

3. Ben is 15 and Ishaan is 6

4. Ben is 19 and Ishaan is 7

Ben is currently 12 years older than Ishaan. To find the difference, take Ben's age and subtract Ishaan's age.

1. 7 - 4 = 3

2. 11 - 5 = 6

3. 15 - 6 = 9

4. 19 - 7 = 12

Thus meaning Ben is 19 and Ishaan is 7.

I hope this helps!

What is the equation of the line in the following graph? 1)y=x+2

Levart [38]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (2, 0) and (-2, -4). Substitute:

$m=\dfrac{-4-0}{-2-2}=\dfrac{-4}{-4}=1$

Therefore we have the equation of a line

$y=1x+b\to y=x+b$

Put the coordinates of the point (2, 0) to the equation:

$0=2+b$ <em>subtract 2 from both sides</em>

$-2=b\to b=-2$

Answer: $\boxed{y=x-2}\to\boxed{3)}$
