Answer:

Door 2

Step-by-step explanation:

To do this problem, we need to use the Pythagorean Theorem. The door is a rectangle and if we draw a line from corner to corner, we have right triangles.

To find the diagonal distance, we have to write and solve the equation below.

3^2 + 9^2 = c^2

9 + 81 = c^2

90 = c^2

c = the square root of 90

The square root of 90 can be simplified to 3 square roots of 10.

. Write an equation that is perpendicular to y=2x – 1 and has y-intercept of -3
blagie [28]

The answer is very simple .

First you need to determine the slope, which is the reciprocal of the first line.

Then,

y = mx + b

m => -1/m

The perperdicular line has a new slope equal to m = -1/2

In the formula (y - y1) = m ( x - x1 ) + b , you should sustitude this value.

So the final equation will be

-3 = -1/2 (0) + b

b = - 3

y = (-1/2)x - 3

That is the solution

Nisha collects comic books, and she convinced her friend Hakim to start collecting as well. Every week, they go to the store tog
andreyandreev [35.5K]

By using the given table, we will get the linear equation:

h = n - 9

<h3>How to find the equation for Hakim?</h3>

We know that they always get comic books together, so always that Nisha's collection increases by one, Hakim's collection will also increase by one, so we will have a linear equation.

Now, if you look at the given table, you can see that Hakim's collection is always 9 units less than Nisha's collection, then the linear equation that models the relation between the two collections, h and n, is really straightforward, it will be:

Hakim's collection = Nisha's collection - 9

Using the variables, we get:

h = n - 9

That is the linear equation Hakim wanted.
