PLEASE HELP ME AND DO IT STEP BY STEP PLEASE!!&lt;1 And &lt;2 Are Complementary Angles. The Measure Of

Answers

Answer 1

Answer:

X=10

Step-by-step explanation:

The measure of the two angles added up is 90 degrees, since it’s a right angle (we know it’s a right angle because of the red square in the corner). You know that <1 is 60, so <2 has to be 30 because the two angles have to add up to 90 degrees. Since <2 is 3x, you have to find a number times 3 that equals 30.

x=10.

To check the answer, 10 * 3 is 30 and 30+60=90 (the total measure of a right angle), so it’s correct.

In New York City, the cost to take a taxi can be represented with the equation y = .40x + 2.50, where x is the number of miles driven and y is the total cost. The cost of a taxi in San Francisco is shown in the table below.

Answers

Answer:

y = 0.45x + 2.85

Step-by-step explanation:

to solve we can first subtract the initial cost by taking the price at 0 miles and subtracting it from one of the higher numbers, we will go with $5.10 at 5 miles for this example

5.10 - 2.85 = 2.25

now we have the price for just the 5 miles separated from the initial cost, but we still need to figure out what each single mile is, so now we just divide by 5, one for each mile

2.25 / 5 = 0.45

so $0.45 is the cost to ride for one mile, and the initial cost is 2.85, now all we have to do is implement those numbers into a formula, since 0.45 is for each mile, it is multiplied by the miles, or x, so that will be put together below

0.45x

then we have the value to add to that, 2.85

0.45x + 2.85

and that is = to y, the cost to ride in a San Francisco taxi

The cost of a taxi in San Francisco is higher compared to New York and the equation of line is y = 0.75x + 2.85

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = 0.40x + 2.50   be equation (1)

where y represents the cost of the taxi in New York for x miles driven

Let the first point be P ( 0 , 2.85 )

Let the second point be Q ( 5 , 5.10 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 5.10 - 2.85 ) / ( 5 - 2 )

Slope m = 0.75

And , the equation of line for the cost of the taxi in San Francisco for x miles driven is given by

y - ( 2.85 ) = ( 0.75 ) ( x - 0 )

Adding 2.85 on both sides , we get

y = 0.75x + 2.85   be equation (2)

So , when x = 1 mile

y = $ 3.60

And , when x = 1 in equation (1) , we get

y = $ 2.90

Therefore , the cost of a taxi in San Francisco is higher compared to New York

Hence , the equation of line is y = 0.75x + 2.85 for the cost of taxi in San Francisco

Amelia works as a babysitter for an hourly wage of $8. Which equation represents the relationship between Amelia's total earnings (y) and the number of hours she works (x)?
1. 8y = x
2. y + 8 = x
3. y = 8x
4. y = x + 8

Answers

Answer:

3. y = 8x

Step-by-step explanation:

y = 8x

earnings (y)=$8×number of hours (x)

8 dollars is her hourly wage and that multiplied by the number of hours she works will give you her total earnings.

Hope this helps! :)

3, y = 8x, is the correct answer. Y represents her total earnings, which is equal to the number of hours she works when multiplied by 8.
