Answer:

It will be parallel

Step-by-step explanation:

3x-6y=12

-6y= -3y+12

y= 1/2y+12

Answer:

(x+2) (x+6)

Step-by-step explanation:

x^2+8x+12

What 2 numbers multiply together to give you 12 and add together to give you 8

2*6 = 12

2+6 = 8

Julia used absolute value to find the distance between 0 and 6 on a number line. She then wrote a similar statement to represent

Schach [20]

Answer:

Absolute value function.

Step-by-step explanation:

The absolute value of a number helps us to calculate the distance between a number and zero, provided the direction does not play an important role.

The absolute value of a number can never be negative since it is the value of distance.

The absolute value function is defined as:

$\mid a \mid = a, a > 0\\~~~~~ = -a, a < 0$

So, it is correct to write the statement that distance between 0 and 6 is equal to distance between 0 and -6.

$\mid 6 \mid = 6\\\mid -6 \mid = -(-6) = 6$

What is the shape graphed by the function r = 1+ sin theta

IRISSAK [1]

Answer: Is known as a "heart" shape.

Step-by-step explanation:

r = 1 + sin(θ)

Let's do it without a graph, let's use only math and logic:

remember that θ is measured from the x-axis

when θ = 0, we have r = 1 (so we have a radius of 1 over the x-axis)

when θ = pi/2, we have r = 1 + sin(pi/2) = 2

when θ = pi, we have r = 1 + sin(pi) = 1

when θ = 3*pi/2, we have r = 1 + sin(3*pi/2) = 0

First, we have symetry around the y-axis,

now, notice that the value of x in θ = 0, θ = pi and θ = 3*pi/2 is the same. so this is not a circle, this is actually a circle where the bottom part is flatted.

But not actually flat, because between θ = pi and θ = 2pi we are in the negative y-axis, so in this region we have two small bumps that connect in the point (0, 0)

This is a kinda "heart" shape.
