James has $20 in his wallet and makes $10 per hour. Kelly has $50 in her wallet but only makes $8 per hour.

sveticcg [70]

Answer:

At 15 hours of work they will be equal.

Step-by-step explanation:

James: y = 10x + 20

Kelly: y = 8X + 50

Set them equal to each other and solve

10x + 20 = 8x + 50 Subtract 8x from both sides of the equation

2x + 20 = 50 Subtract 20 from both sides of the equation

2x = 30 Divide both sides by 2

x =15

Which sequence could be described by the explicit definition: a n = n 2 − 5

kirza4 [7]

The sequence represented by given explicit definition is:

-4,-1,4,11,20,....

Step-by-step explanation:

We will find the terms of the sequence to find the right sequence for given explicit definition

Given explicit formula is:

$a_n=n^2-5$

We will put n=1,2,3,4,5...... in the formula

So,

Putting n=1

$a_1=(1)^2-5\\=1-5\\=-4$

Putting n=2

$a_2=(2)^2-5\\=4-5\\=-1$

Putting n=3

$a_3=(3)^2-5\\=9-5\\=4$

Putting n=4

$a_4=(4)^2-5\\=16-5\\=11$

so, comparing the values with given options we can conclude that

The sequence represented by given explicit definition is:

-4,-1,4,11,20,....
