Answer:
A
Step-by-step explanation:
This is a linear function whose slope is -3 and whose y-intercept is (0, 2). Answer A is correct.
we get x by setting up a proportion.
= ![\frac{21}{5x-1}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B5x-1%7D)
then we cross multiply.
12(5x−1) = 21(2x+2)
60x − 12 = 42x + 42
18x − 12 = 42
18x = 54
<u>x = 3.</u>
plug in 3 for x for <u>LB</u>, which is <u>2x + 2.</u>
<u>LB </u>= 2(3) + 2 = 8
plug in 3 for x for <u>BG</u>, which is <u>5x - 1.</u>
<u>BG </u>= 5(3) - 1 = 14

Answer: it will take 14 months for their weights to be the same.
Step-by-step explanation:
Let x represent the number of months it will take for their weights to be the same.
Katy weighs 105 pounds and is gaining 2 pounds a month. This means that the total weight of Katy after x months is
2x + 105
James weighs 175 pounds and is losing 3 pounds a
month. This means that the total weight of James after x months is
175 - 3x
For their weights to be the same, it means that
2x + 105 = 175 - 3x
3x + 2x = 175 - 105
5x = 70
x = 70/5
x = 14
