Which is a solution to the inequality y > 2 + 9x? Select all that apply.
A (7,67)
B (8,74)
C (5,49)
D (4,37)

Answers

Answer 1

The options that represent solutions to the given inequality are:

A (7,67)C (5,49)

What is the inequality?

The inequality is:

[tex]y > 2 + 9x[/tex]

Item a:

x = 7, hence, the solution is:

[tex]y > 2 + 9(7)[/tex]

[tex]y > 67[/tex]

67 > 65, hence it is a solution.

Item b:

x = 8, hence, the solution is:

[tex]y > 2 + 9(8)[/tex]

[tex]y > 74[/tex]

74 = 74, hence it is not a solution.

Item c:

x = 5, hence, the solution is:

[tex]y > 2 + 9(5)[/tex]

[tex]y > 47[/tex]

49 > 47, hence it is a solution.

Item d:

x = 4, hence, the solution is:

[tex]y > 2 + 9(4)[/tex]

[tex]y > 38[/tex]

37 < 38, hence it is not a solution.

A hiking trail rises 6 feet for every horizontal change of 100 feet. What is the slope of the hiking trail?

Answers

Given:

A hiking trail rises 6 feet for every horizontal change of 100 feet.

To find:

The slope of the hiking trail.

Solution:

We have,

Rise = 6 ft

Run = 100 ft

We know that

[tex]Slope=\dfrac{Rise}{Run}[/tex]

[tex]Slope=\dfrac{6}{100}[/tex]

[tex]Slope=0.06[/tex]

Therefore, the slope of the hiking trail is 0.06.

The slope of the hiking trail is equal to 0.06.

Given the following data:

Vertical distance (rise) = 6 feetHorizontal distance (running) = 100 feet

To find the slope of the hiking trail, we would use the following formula:

Slope is the ratio of the vertical distance measured to the horizontal distance measured.

Mathematically, the slope of a hiking trail is given by the formula:

[tex]Slope = \frac{Rise}{Running}[/tex]

Where:

V is the rising vertical distance of an object.H is the horizontal distance an object runs through.

Substituting the given parameters into the formula, we have;

[tex]Slope = \frac{6}{100}[/tex]

Slope = 0.06

In a regular polygon each interior angle is 140° greater than each exterior angle. Calculate the number of sides of the polygon​

Answers

Answer:

18 sides.

Step-by-step explanation:

The interior and exterior angles sum to 180 so:

       I + E = 180

also  I - E = 140       (given)

So, adding to eliminate E:

      2I = 320

I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.

Since the sum of all exterior angles in a polygon = 360 degrees

- the number of sides = 360 / 20 = 18.

Juan has 240 marbles. This is three times as many marbles as Jon and Jeremy have combined. If Jon has 50 marbles, how many marbles does Jeremy have?

Answers

Answer:

30

Step-by-step explanation:

Let x = number of marbles Jon has

y = number of marbles Jeremy have

3(X + Y) = 240

3(50 + Y) = 240

Divide both sides by 3

50 + Y = 80

Solve for y

Y = 30

Elias had 3 time as much money as munah.Elias spent $240 and munah received $60 from her brother. In the end.Elias and munah had the same amount of money.How much did elias have at first

Answers

Answer:

$450

Step-by-step explanation:

let m represent the amount of money munah has

That means elias would have 3 * m or 3m dollars.

Then, you have m + 60 = 3m - 240

solve:

[tex]m + 60 = 3m -240\\300 = 2m\\m = 150[/tex]

So munah started with $150. Since elias has 3 times as much, they have 150 * 3 = 450
