Last year, Deandre opened an investment account with S5800. At the end of the year, the amount in the account had increed by 7.5%. How much is this
increase in dollars? How much money was in his account at the end of last year?
Increase in amount: $
Year-end amount: $

Step-by-step explanation:

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

Where

I represents interest paid on the amount invested.

P represents the principal or amount invested.

R represents interest rate

T represents the duration of the investment in years.

From the information given,

P = 5800

R = 7.5

T = 1 year

I = (5800 × 7.5 × 1)/100 = $435

Therefore,

The increase in amount is $435

The Year-end amount is

5800 + 435 = $6235

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.
