Lunch + Puzzle + Magazines < 30

9 + 4.50x < 30

-9         -9  (subtract 9 from each side)

4.50x /4.50 < 21/ 4.50 (Make them as fractions.)

x< 4.6 (repeating, so just put a line over the 6.)

Answer: Barry can't buy partial magazines

Write the first four terms of a sequence given the recursive rule below:
777dan777 [17]

Answer:

The first four terms of the sequence is : A)   7, 17, 37, 77.

Step-by-step explanation:

The given function f(n) = 2 x  f(n − 1) + 3

Also, f(1)= 7

<u>FOR n= 2</u>

f(2) = 2 x f(2-1) + 3  = 2 x f(1)  + 3

      = (2 x 7) + 3 = 14 + 3 = 17

⇒f(2) = 17

<u>FOR n= 3</u>

f(3) = 2 x f(3-1) + 3  = 2 x f(2)  + 3

      = (2 x 17) + 3 = 34 + 3 = 37

⇒f(3) = 37

<u>FOR n= 4</u>

f(4) = 2 x f(4-1) + 3  = 2 x f(3)  + 3

      = (2 x 37) + 3 = 74 + 3 = 77

⇒f(4) =77

So, the first four terms of the sequence are 7, 17, 37, 77.

A) is the correct option.

Josh is hiking Glacier National Park. He has now hiked a total of 17 km and is 2 km short of being half of the way done with thi
poizon [28]
Hello!

What we know so far is that Josh has hiked 17km. He is 2km short of being half way done with the hike.

To solve this, we must add 17 and 2 (to find the kilometers that he has hiked and the kilometers that he needs to hike to reach half way.)
17+2= 19

Now we know that 19km is exactly halfway in Josh's hike.
To find the total amount of km in Josh's hike, we must multiply 19 by two. (Half way times two = total amount)

19x2= 38

The total amount of kilometers in Josh's hike is 38km.

I hope this helps you!!

The perimeter of a square is 4 times the length of one side of the square. Which graph represents this situation? *
Arisa [49]

Answer:

A.

Step-by-step explanation:

Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.

Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.

Hence the answer is Graph A.
