Stacy started a banking account with $150 and is spending $7 per day on lunch. This situation models which type of function?

The function which models the situation will be:

Step-by-step explanation:

The slope-intercept form of the linear line equation

where

In our case,

Given that Stacy started a banking account with $150. It means the initial condition is $150

Thus, the y-intercept b = 150

As stacy is spending $7 per day on lunch.

Thus, the rate of change or slope m = 7

now substituting b = 150 and m = 7 in the slope-intercept form

y = mx+b

y = 7x + 150

Therefore, the function which models the situation will be:

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
