The sequence increases in increments of the sum of the term before and the increment for the term before to the current term. For example, 7+5 is 13 and 13+5 is 18 hence the next term is 13+18 is 31. The next term is thus 80. It’s easier to understand if you draw out the term and the number it increases by

Find the sale price to the nearest cent<br> $53 pair of jeans with a 20% discount
Artist 52 [7]

Answer: It is $42.4

Step-by-step explanation: Multiply (0.20)(53), you get 10.6, now that's the price that is discounted, so subtract that from the total, to get $42.4. If you want to check your answer, do 42.4/53 and you would get 0.80, or 80%. That is what you should get since you have a 20% discount from 100% of a product.

Graph the equations to find the solution(s) to the system.
liraira [26]

By graphing both equations, we see that the solutions of the system of equations are  (1.05, 4.05) and  (-4.97, - 1.97)

<h3>How to solve the system of equations?</h3>

Here we have the system of equations:

y = x + 3

y = 13*(x + 5)*(x - 1).

To solve this system graphically, we need to graph both equations and see where the curves intercept.

The graph of the two equations can be seen below.

There are two solutions, one is (1.05, 4.05) and the other is (-4.97, - 1.97)
