(-2,-1) (2,-3)

slope formula

y2-y1/x2-x1

-3-(-1)
____
2-(-2)

Tariq lives in Palm Beach, Florida, and purchased a house for $250,000. The amount of millage for property tax is 11.8. What is
IRISSAK [1]

Answer:

$29500

Step-by-step explanation:

We have been given that Tariq lives in Palm Beach, Florida, and purchased a house for $250,000. The amount of millage for property tax is 11.8%. We are asked to find the amount of property tax that Tariq paid.

To find the amount of property tax paid by Tariq, we need to calculate 11.8% of $250,000.

\text{Amount of property tax paid by Tariq}=\$250,000\times \frac{11.8}{100}

\text{Amount of property tax paid by Tariq}=\$2500\times 11.8

\text{Amount of property tax paid by Tariq}=\$29,500

Therefore, Tariq paid an amount of $29500 in tax.

A new car worth $20,000 loses 20% of its value every year. Is the value of the car represented by a linear or exponential functi
madreJ [45]
Exponential. 

One way to think about this, is to ask how much you will lose each year. The first year you're losing 20% of $20,000 ($4,000). The second year you're losing 20% of 16,000 ($3,200). The dollar value your car loses each year diminishes exponentially, so it is not a linear but an exponential function.

Please help. Which graph represents a function? I think a.
drek231 [11]

graph B ( the lower one )

for a function to be defined there can only be one value of y for each value of x

graph A has more than 1 value of y for given values of x

for example ( - 1, 4 ) and  ( - 1, - 4 ) thus is not a function

graph B only has 1 value of y for a given value of x thus is a function
