Answer:
7x
Step-by-step explanation:
f (x)=x+4=4x,g (x)=5x-2=3x
4x+3x=7x
We know that a1 = -1, and an = 2 * an-1.
We already know that the first time, a1, is -1. We're given the formula to find the next terms in the sequence.
For a given term in this sequence, it will be 2 times the last item in the sequence.
an = 2 * an-1
a2 = 2 * a2-1 = 2 * a1 = 2 * -1 = -2
a3 = 2 * a3-1 = 2 * a2 = 2 * -2 = -4
a4 = 2 * a4-1 = 2 * a3 = 2 * -4 = -8
a5 = 2 * a5-1 = 2 * a4 = 2 * -8 = -16
a6 = 2 * a6-1 = 2 * a5 = 2 * -16 = -32
I believe it is d: whole numbers, integers, and rational numbers
Answer:
x=-6
Step-by-step explanation:
−5x+10=40
−5x+10−10=40−10
−5x=30
−5x/5=30/5
x=−6
Answer:
<u>The percentage loss per gallon is 23.17%</u>
Step-by-step explanation:
Original price per gallon = $ 2.59
Discounted price per gallon = $ 1.99
Now, let's calculate the percentage loss per gallon, using the Direct Rule of Three, as follows:
Price Percentage
2.59 100
1.99 x
*****************************
2.59 * x = 1.99 * 100
2.59x = 199
x = 199/2.59
x = 76.83
Percentage loss = 100 - 76.83
<u>Percentage loss = 23.17%</u>
