During a sale at the bookstore,books sold for $3 and magazines sold for $2.50.Jan spent $16 and bought a total of 6 books and magazines.how many of each did she buy

Answers

If you would like to know how many of each did Jan buy, you can calculate this using the following two equations:

b ... the number of books
m ... the number of magazines

$16 = b * $3 + m * $2.50 ... 16 = 3 * b + 2.50 * m
b + m = 6 ... b = 6 - m
__________________
16 = 3 * b + 2.50 * m

16 = 3 * (6 - m) + 2.50 * m

16 = 3 * 6 - 3 * m + 2.50 * m

16 - 18 = - 3 * m + 2.50 * m

- 2 = - 0.50 * m     /0.50

m = 2 / 0.50

m = 4 magazines 

b = 6 - m = 6 - 4 = 2 books

Result: Jan bought 4 magazines and 2 books.
4 magazines @ $2.50 a piece
2 books @ $3 a piece
6 in total for $16

Which graph represents the solution set of the system of inequalities?

Answers

Answer:

D (right-down graph)

Step-by-step explanation:

y = ax+b - linear function,

a>0 - ascending

a<0 - descending

y=\frac13x-3 - ascending function, because a=\frac13, so a>0

y=-3x-3 - descending function, cause a=-3, so a<0

We refuse both graphs on the left side, these are two ascending functions

y\ge\frac13x-3 is the area above the ascending function y=\frac13x-3

y<-3x-3 is the area below the descending function

This causes that D (right-down graph) is a correct answer

Step-by-step explanation:

Step 1: Define

f(x) = 4x - 3

f(x) = 33

Step 2: Solve for x

  1. Substitute:                    33 = 4x - 3
  2. Isolate x term:               36 = 4x
  3. Isolate x:                       9 = x
  4. Rewrite:                        x = 9

What is the converse of the statement below??
x>Y

Answers

Converse means switching the hypothesis and conclusion of a conditional statement. The converse of x > y, is y > x. Therefore, the answer to your question is y > x, switching the hypothesis and conclusion of the statement.
