A notebook is 3/10 off the original price. How could this be written as a decimal? What percentage is the discount?

A decimal: 0.3     A percentage: 30%

Step-by-step explanation:

To calculate the decimal:

3/10=0.3

Three divided by 10 is 0.

After writing the zero put a little dot beside it.

Then you add a little zero to three to make it 30

Then it becomes 30 divided by 10 and the answer is three so the decimal is 0.3

To calculate the percentage:

You can use the decimal. So we say 0.3 multiplied by 100 because a percentage is out of 100.

The answer is 30%

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
