Two angles are complimentary. One angle measures 69 degrees. The other measures ( 5n + 1). What is the value of n?

iren [92.7K]

Answer:

Step-by-step explanation:

complimentary angles, when added = 90 degrees

69 + 5n + 1 = 90

5n + 70 = 90

5n = 90 - 70

5n = 20

n = 20/5

n = 4 <====

Which of the following graph represents the solution set for 5x+38 ≤ 4(2-5x)

Dvinal [7]

Answer:

Option C

Step-by-step explanation:

Given inequality is,

5x + 38 ≤ 4(2 - 5x)

5x + 38 ≤ 8 - 20x [Distributive property]

5x + 20x + 38 ≤ 8 - 20x + 20x [By adding 20x on both the sides of the inequality]

25x + 38 ≤ 8

(25x + 38) - 38 ≤ 8 - 38 [By subtracting 38 on both the sides of the inequality]

25x ≤ -30

$\frac{25x}{25}\leq -\frac{30}{25}$ [Dividing by 25 on both the sides of the inequality]

x ≤ 1.2

Therefore, Option (C) will be the correct graph.

List the coordinates of FOUR vertices that create the feasible region on the graph. Submit your answer in the form of FOUR order

hoa [83]

Answer:

The coordinates of the vertices are;

(200, 200), (300, 200), (300, 0), (0, 500)

Step-by-step explanation:

The vertices are the corners of a polygon. It is the point where an angle is formed by the intersection of two lines

The feasible region is the solution space of the points of the variables that meet the specification of the problem set by means of a constant or the definition of inequalities or equations

From the graph of the function of inequalities, we have that the four vertices are the four points where the lines bounding the area of the feasible region of the inequalities meet

The coordinates of the vertices are (200, 200), (300, 200), (300, 0), (0, 500).
