Which correctly describes how the graph of the inequality 5x + 2y ≥ 13 is shaded? (1 point) Above the solid line Below the solid line Above the dashed line Below the dashed line

Answers

Answer:

The graph of inequality $5x+2y\geq 13$ is above the solid line.

Step-by-step explanation:

Step-by-step explanation:

An inequality on a coordinate plane consist of a boundary line and an area in which each point is a possible solution.

* If the inequality has a sign or , then the line will be a solid line and its point are included in the solution.

* If the inequality has a sign '>' or '<' , then the line will be a dotted line and its point are not included in the solution.

Given: The linear inequality: $5x+2y\geq 13$

Then, the equation of the boundary line is; 5x+2y =13 ......[1]

we can write this as;

$2y = -5x+13$

Divide by 2 we get;

$y = -(5)/(2) x + (13)/(2)$ ......[2]

Compare this boundary line equation with the general point slope intercept line i.e, y = mx+b where m is the slope and b is the y-intercept.

Therefore, the slope of the this line is, m = $-(5)/(2)$

and a y-intercept (b) = $(13)/(2)$ = 6.5

To find x -intercept:

Substitute y =0 in to solve for x;

$5x+0 =13$

Simplify:

$x =(13)/(5) = 2.6$

Therefore, the x-intercept is 2.6

Now,

Plot $y = -(5)/(2) x + (13)/(2)$ ( as a solid line because $y\geq$ included equal to)

and shade the area above as $5x+2y\geq 13$ as shown below in the graph

The answer is above the solid line.

Which of the following best describes a
rational number
A fraction
deo
A Any integer or whole number
B Any decimal or integer
C
All decimals, integers, and whole
numbers
D
Numbers that can be written as
fractions

Answers

Answer:

D Numbers that can be written as fractions

Step-by-step explanation:

A rational number is one that can be written as a ratio: a fraction with integer numerator and denominator.

The term "decimal" as used here is sufficiently non-specific that we cannot seriously consider it to be part of a suitable answer. A terminating or repeating decimal will be a rational number. A non-terminating, non-repeating decimal will not be a rational number.

While integers and whole numbers are included in the set of rational numbers, by themselves, they do not constitute the best description of the set of rational numbers.

The equation represent the situation is:

First let x be number of small apartment

Since the total apartment is 18

Then number of large apartment is 18 – x

So the equation is:

17,600 = 800x + 1200(18-x)

Simplifying

17,600 = 800x + 21,600 – 1200x

400x = 4000
