The two equations expressed in this scenario will be

y = 13x + 34

And

y = 30x

I like substitution, so let’s use that

Plug in y = 30x for y in the first equation

30x = 13x + 34

Subtract

17x = 34

x = 2

Plug in 2 for x in any equation

y = 30(2)

y = 60

It would be 2 hours and she would pay $60 dollars

Which graph best represents the equation created when the slope of y = 6x is changed to 0?

luda_lava [24]

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

<h3>What is a linear function?</h3>

A linear function is in the form:

y = mx + b

Where m is the slope (rate of change) and b is the y intercept

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

Find the measure of one interior angle in each regular polygon. Round your to nearest tenth if necessary.

e-lub [12.9K]

The value of the interior angle of the regular polygon is calculated using the formula (n - 2) 180 / n where n is the number of sides of the regular polygon.

Step-by-step explanation:

A regular polygon refers to a multi-sided convex figure where all the sides are equal in length and all the angles have equal degree measures.

The triangle has 3 interior angles of 60 degrees

The square has 4 interior angles of 90 degrees.

The pentagon has 5 interior angles of 108 degrees .

The formula for the interior angle of a regular polygon is given by,

( n − 2 ) 180 / n

where n refers to the number of sides.

Triangle : (3 - 2) 180 / 3 = 60 degree.

Square : (4 - 2) 180 / 4 = 90 degree.

Pentagon: (5 - 2) 180 / 5 = 108 degree.

Find the perimeter of the triangle in units. Round to two decimal places as necessary.

Dimas [21]

Answer:

54.56 units

Step-by-step explanation:

The vertices are:

K(-12,2), L(-7,12), J(3,-10)

Find the sides using distance formula:

KL = $\sqrt{(-7+12)^2+(12-2)^2} = \sqrt{125}$ ≈ 11.18
LJ = $\sqrt{(3+7)^2+(-10-12)^2} = \sqrt{584}$ ≈ 24.17
KJ = $\sqrt{(3+12)^2+(-10-2)^2} = \sqrt{369}$ ≈ 19.21

Find perimeter:

P = KL + LJ + KJ
P = 11.18 + 24.17 + 19.21 = 54.56 units

Lex was chatting with his friends thomas and mike. He was wondering how much it will cost him to take a taxi from his house to w

UNO [17]

Answer:

$28.3

Step-by-step explanation:

x=rate for 1km

y=initial fee

Mike: $35 for 15km -> 35 = 15x + y

Thomas: $24.50 for 10km -> 24.50 = 10x + y

Using those two equations we see the following:

Mike paid $10.5 more for 5 more km. The initial fee remains unchanged, so we can calculate the rate for 1km, which is 10.5/5=2.1.

35 = 15x + y

24.50 = 10x + y

10.5 = 5x

2.1=x

Using that value with one of the original equations we can calculate the initial fee.

35 = 15x + y

35 = 15*2.1 + y

35 = 31.5 + y

3.5 = y

Mike paid 15*2.1=31.5 ($2.1 for every km) plus the initial fee, his total was $35.

We subtract the 31.5 from the 35(total) and get the initial fee, which is $3.5.

Let's see what Lex will pay:

Km travelled times 2.1 (the rate for 1km) plus 3.5 (the initial fee).

12*2.1 + 3.5 = 28.3

Lex will pay $28.3 for the same taxi company to travel 12 km.
