In-s [12.5K]

Answer:

$25,000=50d+12,100$

Step-by-step explanation:

Let d represent the number of pizza delivery days.

We have been given that a pizza delivery worker drives the motor scooter only on days he is working, during which he drives an average of 50 miles per day. So the number of miles driven in d days will be 50d.

As the delivery worker purchased a used motor scooter that had been driven 12,100 miles. This means that initial value or y-intercept will be 12,100.

$\text{Total number of miles the scooter has been driven}=\text{Miles driven in d days+Initial value}$

Upon substituting our given values we will get,

$25,000=50d+12,100$

Therefore, the equation $25,000=50d+12,100$ models the total number of miles driven in d days of pizza delivery.

Use substitution
3x = -x - 4
Add x to both sides
4x = -4, x = -1
Y = 3(-1), y = -3
Solution: x = -1, y = -3

Li graphed the equation y=2x+3. Which table of values did Li use to create her graph?

Natali5045456 [20]

Answer:

See attached picture.

Step-by-step explanation:

To graph the line, start at (0,-3) since b=

-3 in the equation. This is the y-intercept.

Mark this point. From this point, move

down 2 units and to the right 1 unit. Mark

this new point at (1,-1). Connect the points

with a line. See attached picture.
