Good strategy for using slope formula

1 answer:

3 0

I personally use y2-y1 over x2-x1 because it's simple. Plot two y values and two x values. The first ones you plotted are x1 and y1, the others are x2 y2. Now subtract y2-y1 and x2-x1. Afterwards, divide the y value by the x value, that will give you slope.

Drag each real-world situation to the correct column to show whether it can be modeled by combining additive inverses to get 0.

Answer:

. An investment account earns 2.8% simple interest.

Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.

B). The price of a stock varies by 2.8% each week.

Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.

Therefore, the answer is NEITHER.

C). An investment account earns 2.8% compound interest, compounded monthly.

Formula to get the value of the final amount in the account is,

Final value = Initial value ×

Here 't' = Duration of investment

It's an EXPONENTIAL FUNCTION.

Answer:

27 13/60

Step-by-step explanation:

What you have tried to do is not an impossible way to do it. What you could do is set your fractions and whole numbers like this.

( 7 + 1/10) * (3 + 5/6) I don't know if you know what FOIL is, but that is the way to proceed.

First: (meaning the first in each factor ). 3 * 7 = 21
Outside: (meaning the two terms near outside the brackets) 7 * 5/6 = 5 5/6
Inside: The two terms closest to the * sign 1 / 10 *3 = 3/10
Last: The two end terms (1/10 * 5/6 = 5/60 5/60

Now you can add. 21 + 5 is the whole number amount = 26

Add the fractions

5/6 + 3/10 + 5/60 The lowest common multiple is 60
50/60 + 18/60 +5/60 = 73 / 60 = 1 and 13/60

Add that to 26 and you get 27 13/60
