Answer:

Neither

Step-by-step explanation:

-12x + 3y = 3

y = 4x + 1

y = mx + b

The second equation given is set up in the correct form already (y = 4x + 1)

We have to convert the first equation into the same format

-12x + 3y = 3

Isolate the y

3y = 3 + 12x

Divide the 3 from the y and the other side

y = 1 + 4x

y = 4x + 1

This is the same as the first equation

They can only be parallel if their slope (m or 4 in this case) is the same and their y-intercepts (b or 1 in this case) are different. Since the equations are the exact same and do not fit the y-intercept criteria for parallel, they cannot be parallel. If they were perpendicular, their lines must cross. This means they have to contain reciprocals or opposite slopes. Our slope here for both of them is 4 or 4/1. Since neither are the opposite (which would be 1/4), it is not perpendicular. Therefore, the answer is neither

100 POINTS PLEASE HELP ASAP!!!!<br> Explain the concept of using cancellation to reduce fractions.

Setler79 [48]

Explanation:

A "reduced" fraction is one that has mutually prime numerator and denominator. That is, the numerator and denominator have no common factors.

A fraction is "reduced" by canceling common factors from numerator and denominator. If "a" is a factor common to the numerator and denominator of a fraction, that fraction can be written with "a" canceled from each:

$\dfrac{ab}{ac}=\dfrac{a}{a}\cdot\dfrac{b}{c}=1\cdot\dfrac{b}{c}=\dfrac{b}{c}$

Here is a numerical example:

$\dfrac{2}{4}=\dfrac{2\cdot 1}{2\cdot 2}=\dfrac{2}{2}\cdot\dfrac{1}{2}=\dfrac{1}{2}$

A numerator factor and a denominator factor "cancel" because their ratio is 1, the identity element for multiplication. Anything times 1 is just that thing.

Enter the inequality of the graph below.

aev [14]

The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y $\leq$ -3x+8
