Step-by-step explanation:
just look at the image.
first in this you need to get rid of the 6 by the x, since its 6 times x you need to divide it by 6 to remain with x, you must do this on both sides to make it fair. you will remain with x < 4. 2 would then be the only answer to make it true.

Step-by-step explanation:
<u>Linear:</u>
1. During the spring, the grass in Gianna's yard grew inch per week.
Equation: where x is the number of spring weeks, y inches is the height of the grass after x weeks.
2. Rita babysits. She worked 2 hours and earned $24. She worked 3 hours and earned $36.
Equation: where x is the number of hours, y is the amount Rita earned in x hours.
<u>Exponential:</u>
1. The population of the town was 25,000 in 1980. Then the population increased by per year.
Equation: where x is the number of years, y is the population after x years passed since 1980.
2. A car was worth $18,500 when it was new. Then the value decreased 18% per year.
Equation: where x is the number of years, y is the car price after x years passed.
<u>Neither linear nor exponential:</u>
Albert went on a hike. After 1 hour, he had hiked 4 miles; after 2 hours he had hiked 7 miles; after 3 hours he had hiked 11 miles.
The differences 7 - 4 = 3, 11 - 7 = 4 are different, so the function is not linear. Also it is not exponential, becayse each next number of miles is not multiplied the previous number of miles by some number.
