An angle measures 30 degrees.

1 answer:

8 0

Complimentary angels are angels that together add up to 90 degrees.

To find the measure of an angles compliment, simply subtract the degree you are given from 90.

90 degrees - 30 degrees = 60 degrees.

Hope this helps! :)

The fuel efficiency of one type of car is recorded in a scatterplot where the amount of gas used, x (in gallons), is paired with

sukhopar [10]

Answer:

The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled. The slope is 28, which represents the miles that can be traveled with 1 gallon of gas

Step-by-step explanation:

Let

x----> the amount of gas used in gallons

y ---> the distance traveled in miles

we have

$y=28x$

This linear equation represent a direct variation

The y-intercept is the value of y when the value of x is equal to zero

For x=0, y=0

That means ----> The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled

The slope is $m=28\ \frac{miles}{gallon}$

That means ----> The slope is 28, which represents the miles that can be traveled with 1 gallon of gas

1 (-2,2) Write the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the poi

lozanna [386]

Answer:

y = -5x - 8

Step-by-step explanation:

Take the points (-5,-4) and (0,-3) plug them into this formula to get the slope.

$\frac{y2 - y1 }{x2 - x1}$

Now plug in your points

$\frac{-3 - (-4)}{0 - (-5)} \\\\\frac{1}{5}$

Since you're slope is 1/5 the slope of the perpendicular line is going to be the totally opposite -5 is the slope of the perpendicular line.

Now plug in -5 and the point (-2,2) into y = mx + b to get the y-intercept

2 = -5(-2) + b (b represents the y-intercept)

2 = 10 + b (subtract 10 from both sides)

-8 = b

The perpendicular line looks like this y = -5x - 8

Hope this helps ya! Keep smiling!
