For the Item that costs $64 before tax the sales tax is $6
Hence for the item that costs $1 before tax the sales tax is $(6/64), by the rule of proportions or unitary method
Hence for the item that costs $100 before tax the sales tax is $[100*(6/64)], by the rule of proportions
which is = $75/8 or $9.45


Therefore, the item having a Sales tax of $9.45 or $75/8 costs $100 before tax
thus the item having a Sales tax of $1 costs $[(100*8)/75] before tax, by the rule of proportions or unitary method
thus the item having a Sales tax of $8.25 costs $[(100*8*8.25)/75] before tax, by the rule of proportions
which is = $88

Does anybody know this? Which of the properties of real numbers is illustrated in the following example.
Elenna [48]

The property of real numbers that was illustrated in the above example is known as the: D. inverse property.

<h3>What is the Inverse Property of Real Numbers?</h3>

The inverse property of real numbers states that if you add the opposite of a number together with that number, the result would be zero.

For example, if "a" represents a number, the opposite of the number "a" is -a.

Applying the inverse property of real numbers, it states that: a + (-a) = a - a = 0. Both numbers will cancel each other to give zero.

In the same vein, as shown in the image given above:

6 is a number

The opposite of 6 is -6.

Applying the inverse property of real numbers, we have:

6 + (-6) = 0.

In conclusion, we can state that given the expression, 6 + (-6) = 0, the property of real numbers that was illustrated in the above example is known as the: D. inverse property.

Can somebody please help me with this question and provide an explanation?
SSSSS [86.1K]

Answer:

first of all the formula

y = mx+c

where m is slope and c is y-intercept.

now substitute the values-

y = 2x - 5

(for the slope here is 2 and the part where the line intercepts y axis is -5

therefore

y = 2x-5
