Before leaving to visit Mexico, Levant traded 270 American dollars and received 3,000 Mexican pesos. When he returned from Mexic
erica [24]

The amount of dollars that Mr. Levant would exchange for 100 pesos on his return is <u>$9</u>.

<h3>What is an exchange rate?</h3>

An exchange rate is a rate that is used to convert one nation's currency to another.

The exchange rate is based on the purchasing power of each nation's currency.

<h3>Data and Calculations:</h3>

Dollars before traveling to Mexico = $270

Value of Mexican pesos received for $270 = 3,000 pesos

Exchange rate = $1 = 11.11 pesos (3,000/$270)

Amount of pesos left after the trip = 100 pesos

Value of 100 pesos in dollars = <u>$9</u> (100/$11.11)

Thus, the amount of dollars that Mr. Levant would exchange for 100 pesos on his return is <u>$9</u>.

Find each key feature of the function shown in the graph. Write the range and domain in interval notation, and assume all values
gayaneshka [121]

The domain of the graph is  -8 while the range of the graph is -4\leq x.

  • The domain of the graph is input values of "x" for which the function exists while the range is the output values "y" for which the function exists.

For the graph, the domain will be the values of the graph along the x-axis.

  • Domain = -8 (Note that -8 is not included)

  • For the range, the interval is given as: -4\leq x. Note that the value of 4 is not included since it is opened.

Find the area of the rectangle below by multiplying its length and width.
wariber [46]

Hello!

When multiply binomials together, we should use the FOIL method.

The FOIL method is an acronym for First, Outer, Inner, and Last.

First, let's set up the expression.

(7x - 1)(3x - 2)

Now, we can multiply in accordance with the FOIL method.

First: 7x · 3x = 21x²

Outer: 7x · -2 = -14x

Inner: -1 · 3x = -3x

Last: -1 · -2 = 2

Now, we simplify the inner terms.

21x² - 14x - 3x + 2

21x² - 17x + 2

Therefore, the area of the rectangle is 21x² - 17x + 2.
