Answer:

x=2

Step-by-step explanation:

3x+4=10

subtract four on both sides, you will get 3x=6, divide by three on both sides, x=2

Guys I need the answers to number 16
Umnica [9.8K]
#16:  Let's clear the fraction on the way to solving this inequality for x.  By mult. the given inequality by 2, we'll get -2 (is greater than) x+4.  We want x to be positive.  So, leave it where it is.  Subtract 4 from both sides of this inequality.  We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6.  What would the graph of that simple inequality look like?

Graph it.  (Hint:  The graph is a straight dashed line, and you must shade one side of it, but not the other side.

A group of students is arranging squares into layers to create a project. The first layer has 5 squares. The second layer has 10
True [87]

Answer:

  • Recursive formula:

                                         a_1=5;a_n=5+a_{n-1},n>0

Explanation:

All the shown formulae in the choice list are recursive formulae instead of explicit formulae.

Explicit formulae that represent arithmetic sequences are of the form:

  • a_n=a_1+(d-1)n

That kind of formula permits to determine any term knowing the first term, the number of the term searched, and the common difference (d).

On the other hand, the recursive formulae let you to calculate one term knowing the previous term and the difference.

In this case, the difference in the number of squares of two consecutive terms is:

  • differece = number of squares in the second layer - number of squares in the first layer.

  • d = 10 - 5 = 5

Then, the recursive formula is:

  • a_1=5;a_n=5+a_{n-1},n>0
