Answer:

D. 58

Step-by-step explanation:

The multiplication and division are performed first.

... 32 +6·5 -7 +12/4

... = 32 +30 -7 +3

Then, the Order of Operations tells you to do the addition/subtraction left to right. Of course, if you keep the sign with the number, you can do the addition in any convenient order.

... = 62 -7 +3

... = 55 +3

... = 58

What is the relationship between the following ordered pairs 0,6 2,5 4,4 and 6,3 keep in mind it will be a two step process

Find the first rate of change...

(5-6)/(2-0)=(4-5)/(4-2)=(3-4)/6-4)=-1/2

So this equation has a constant velocity which means that it is linear and can be expressed as y=mx+b where m=slope=velocity and b=y-intercept, value of y when x=0...we saw earlier that the velocity or slope is -1/2 so:

y=-x/2+b, and we can use any point to solve for b, I'll use (6,3)

3=-6/3+b

3=-2+b

b=5

So the relationship if the function:

y=-x/2+5  or more neatly...

y=(10-x)/2

The first three terms of a Fibonacci sequence are n 3n 4n find the sixth term I FB the sequence
Amiraneli [1.4K]

Answer:

<h2>18n</h2>

Step-by-step explanation:

In the Fibonacci sequence In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1.

Given data

First term= n

second term = 3n

third term = 4n

According to Fibonacci sequence the fourth term is

F4= F2 + F3\\F4=3n+ 4n= 7n

the Fifth term is

F5= f3 + f4\\f5= 4n+7n= 11n

hence  the sixth term is

F6= F4+F5\\   F6= 7n+11n= 18n
