Determine if the given pair of lines is parallel, perpendicular or neither.
lana66690 [7]
It’s neither, and this is because the slope is not opposite or the same, the same y intercept yes...but there isn’t any parallel or perpendicular features...you can see this when you graph it :)

In Need of help please Help :c
Oksanka [162]

Answer:

  • proportional: A, B, D, G, I
  • non-proportional: C, E, F, H

Step-by-step explanation:

Any relation with a non-zero initial value or y-intercept is non-proportional. Any relation that has a constant ratio between output and input is proportional.

  C has an initial value of 7

  E has a y-intercept of -3

  F has an initial value of 2.00

  H has an initial value of 5

All of these are non-proportional. The remainder are proportional.

7. algebra sara allen is interested in buying a notebook
seropon [69]

A percentage is a way to describe a part of a whole. The regular selling price of the computer notebook will be $937.5.

<h3>What are Percentages?</h3>

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Let the selling price of the computer notebook be represented by x.

Now, if Sara buys the computer this week, the selling price of the computer will be (100%-16%)x = 0.84x.

Also, the saving she made by buying this week will be $150, therefore, we can write,

x-0.84x = $150

0.16x = $150

x = 937.5

Hence, the regular selling price of the computer notebook will be $937.5.
