Answer:

Parallel

Step-by-step explanation:

Move all the terms so that both equations look like y = mx +b

-3x = 3 - y

y = 3x + 3

3 + y = 3x - 2

y = 3x - 2 - 3

y = 3x - 5

They have the same slope, but not the same y-intercept, so they are parallel

Answer:

$\large\boxed{-\dfrac{8}{\sqrt{63}}}$

Step-by-step explanation:

$\csc\theta=\dfrac{1}{\sin\theta}\\\\\cos\theta=-\dfrac{1}{8}\qquad\text{use}\ \sin^2\theta+\cos^2\theta=1\\\\\sin^2\theta+\left(-\dfrac{1}{8}\right)^2=1\\\\\sin^2\theta+\dfrac{1}{64}=1\qquad\text{subtract}\ \dfrac{1}{64}\ \text{from both sides}\\\\\sin^2\theta=\dfrac{64}{64}-\dfrac{1}{64}\\\\\sin^2\theta=\dfrac{63}{64}\to\sin\theta=\pm\sqrt{\dfrac{63}{64}}\\\\180^o$

$\csc\theta=\dfrac{1}{-\frac{\sqrt{63}}{8}}=-\dfrac{8}{\sqrt{63}}$

500ft of lights to hang the width of the room is 70ft what is the length of room if she can hang all the lights so that they go

eduard

Answer:

180 ft

Step-by-step explanation:

We are working to find the perimeter here. Let x represent the length of the room.

We know that the formula to find the perimeter of something is 2L + 2W = P. Here, we know the required perimeter and the width of the room.

Our equation is now: 2x + 2(70) = 500

Now we have to find x, we'll start by multiplying 70 by 2.

2x + 140 = 500

Now we can solve for x:

Subtract 140 from both sides

2x = 360

x = 180

The length of this room is 180 ft.

2(180) + 140 = 500

360 + 140 = 500

Jonathon paid $237 for 15 pizzas, which included the $12 delivery charge. How much will he pay for 22 pizzas

RUDIKE [14]

237-12=225=cost of 15 pizzas without delivery charge
225/15=15=cost per pizza
15*22=$330=cost of 22 pizzas

What is the range of y=−x2−6x+1?

djyliett [7]

Answer:

All real numbers / (-∞, ∞) / R

Step-by-step explanation:

The equasion provided is a linear equasion meaning it can be written in the y=ax+b format, where both a and b are real numbers. All linear eqasions have a range of all real numbers, you can write this using the three solutions provided.

You can solve this two ways, number one would be to put this in a graphing calculator and number two would be reducing the equasion to the y=ax+b format.

<h2>Method 1:</h2>

look at image provided. The app is PhotoMath.

<h2>Method 2:</h2>

Write the equasion:

y = -2x - 6x + 1

Collect like terms:

y = -8x + 1

This now proves that the equasion is linear becuase you can write it in the y=ax+b format. a being -8 and b being 1.
