Answer:

<em>7, 22</em>

Step-by-step explanation:

Let S = the smaller number.

"The larger number is 1 more than 3 times the smaller number."

The larger number is 3S + 1.

The difference between the numbers is 15, so the larger number minus the smaller number equals 15.

3S + 1 - S = 15

2S + 1 = 15

2S = 14

S = 7

The smaller number is 7.

larger number = 3S + 1 = 3(7) + 1 = 21 + 1 = 22

The larger number is 22.

sophie was 28 years old when daughter Nichole was born. In how many years will Sophie be two years less than still times Nichole
Kamila [148]
It will take 6 years for that to happen. 

You can find this by setting Nichole's age as x and Sophie's age as x + 28 since she will always be 28 years older. 

Now we are looking for a time that Sophie's age is equal to 2 less than 6 times Nichole's age. So we can set up the below equation. 

6(x) - 2 = x + 28
6x - 2 = x + 28
5x - 2 = 28
5x = 30
x = 6

This let's us know that it needs to be when Nichole is 6, which is 6 years in the future.

(y2 - y1) / (x2 - x1)

(8 - 8) / (-8 + 7)

0 / -1

the slope is 0

you could also see this because the y value doesn't change

if the y value doesn't change the slope is 0, if the x value doesn't change the slope is undefined
