Answer:

Unit rate = 20.8 ft/s

Step-by-step explanation:

We are given rate for 644.8 ft in 31 s

We need to find unit rate. We will calculate how many feet move in 1 second.

When rates are expressed as a quantity of single unit.

Such as 2 feet per second (It means in 1 seconds move 2 feet)

5 miles per hour ( In 1 hour move 5 miles)

We will calculate in 1 second how much feet.

In 31 seconds = 644.8 ft

In 1 second = 644.8÷31

Unit rate = 20.8 ft/s

Tina is saving to buy a notebook computer. She has two options. The first option is to put $500 away initially and save $30 ever
Jlenok [28]
First option:
y=money saved
x=number of months

y=30x+500

Second option:

y=50x+200

We have this system of equations:

y=30x+500
y=50x+200

We can solve this system of equations by equalization method
30x+500=50x+200
30x-50x=200-500
-20x=-300
x=-300/-20
x=15

so;
y=30x+500
y=30(15)+500
y=450+500
y=950

Answer; after 15 months, she would save the same amount using either option, the amount saved in either option will be $950.

Not parallel to y=6x+2
bija089 [108]

Hello there! A line that is not parallel to the line given, y = 6x+2, would have a slope value other than 6.

This is because any lines with the same slope and different y-intercepts are parallel to each other, so for them to be not parallel, the slopes would have to be different.

Hope this helps, and have a great day! :)
