What is " ( ) " called?

Mathematics
2 answers:
Hitman42 [59]3 years ago

() Are called parenthesis, and they are used to contain a part of a sentance or to seperate terms in math.

Examples:

I didn't want to explain (it was a long story).

2+3(2+1)

If the use is in math, you always do what is inside the parenthesis first.

For example:

2 * 2 + 2 + 1

4+2+1

6+1

7 is the answer when no parenthesis are added.

2 * (2 + 2) + 1

2 * 4 + 1

8 + 1

9 is the answer when parenthesis are added, because you do the operations inside of parenthesis first.


Hope this was helpful!

What is the answer to this question?<br> Y=x^2-1 with the input as 5
mixas84 [53]

We can see that, when the input is 5, the output is 24.

<h3>How to evaluate an equation?</h3>

Here we have the equation:

y = x^2 - 1

Where y is the output and x is the input.

We want to evaluate it with the input as 5, so we need to replace the variable x by the number 5, we will get:

y = 5^2 - 1 = 24

Then we can see that, when the input is 5, the output is 24.

Write equation for the line with a slope "undefined" and has the same x-intercept as x−y−1=0
Mariana [72]

Answer:

Step-by-step explanation:

Lines with undefined slopes are perfectly vertical, of the form "x = ". A line with "the same x-intercept" as the given line that has an undefined slope will be the line that we want. I know that sounds confusing; we'll work through it then I'll explain it better. In order to find the x-intercep of the given line, solving it for y will make it a bit easier to "see". Therefore,

-y = -x + 1 and

y = x - 1. The x-intercept exists when y = 0, so setting y equal to 0 and solving for x:

0 = x - 1 and

1 = x. That's the x-intercept. It's also the line that we want that has an undefined slope, because "x = " lines are lines vertical lines and vertical lines have undefined slopes.

x = 1 is the line you want.

Leokris [45]

Answer:

$125

Step-by-step explanation:

if there was a discount of 20%, the sales price is 100 - 20 = 80% of the original price

let a = original price

this equation can be used to represent the question

a x 0.8 = 100 ]]divide both sides by 0.8

a = 100 / 0.8 = 125
