It's a linear function. We need only two points to sketch the graph.

f(x) = -5x + 4 → y = -5x + 4

for x = 0 → y = -5(0) + 4 = 0 + 4 = 4 → (0, 4)

for x = 1 → y= -5(1) + 4 = -5 + 4 = -1 → (1, -1)

The domain and the range is the set of all real numbers.

Answer/Step-by-step Explanation:

Circumference of a circular object = πd

Where,

π = 3.14,

d = diameter

Circumference of hula pop with diameter of 35 in:

Circumference = πd = 3.14*35 = 109.9 in

Diameter of circular pond with a circumference of 556 ft:

556 = 3.14*d

Divide both sides by 3.14

556/3.14 = d

177.07 = d

d ≈ 117 in

Circumference of magnifying glass with a diameter of 5.2 in:

Circumference = πd = 3.14*5.2 = 16.328 ≈ 16.4 cm

Diameter of car tire with a circumference of 71.6 in:

71.6 = 3.14*d

Divide both sides by 3.14

71.6/3.14 = d

22.80 = d

d ≈ 22.8 in

Which of these expressions is equivalent to log (20 27)
maria [59]
If the problem is referring to the equivalent logarithmic equation log (20 *27).
We can easily find and solve its equivalent expression using one of the many identities available in logarithmic. 
We can have the expression:
log (20*27) = log 20 + log 27

What is an example of a country with this economic system?
Viktor [21]

Answer:In a free market economy, the law of supply and demand, rather than a central government, regulates production and labor. Companies sell goods and services at the highest price consumers are willing to pay, while workers earn the highest wages companies are willing to pay for their services. A purely capitalist economy is a free market economy; the profit motive drives all commerce and forces businesses to operate as efficiently as possible to avoid losing market share to competitors.

Ella earns 1.5 her normal hourly rate for overtime pay. Last week, Ella earned $72.00 in overtime pay for 4 hours. What is Ella'
mr_godi [17]

Answer:

Ella's normal hourly pay is $12 per hour.

Step-by-step explanation:

Let us assume that the Ella's Normal hourly pay = $x per hour

Over hourly pay = 1.5 times ( Normal pay)

                           = 1.5 ( x)  =  $ 1.5 x

⇒Ella earns $1.5x in 1 hour of overtime.

So the amount she earns in 4 hour of overtime =  4 times (per hour pay)

                                                                                = 4 ( $1.5x)   = $ 6 x

The amount Ella earned in 4 hours of over time = $72.00

According to the question:

$ 6 x  = $72.00

or, x = 72/6

       =12

or , x  =  $12

Hence, Ella's normal hourly pay is $12 per hour.
