PLEAAE HELP Tiffany practices her guitar for hour each day. How many hours does she practice in 7 days? Make an equation to solve the problem.​

7n

Step-by-step explanation:

Let :

The number of hours of practice per day = n

The number of practice hours in 7 days can be calculated thus :

Number of hours of practice per day * number of days

(n * 7) = 7n

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
