Answer: [-1/8, infinity) , {x | X greater than or equal to -1/8}

Step-by-step explanation:

Domain is what x can be. Thus, in the function f(x), we place limits such as x cannot make the square root a negative number because then it would not be a real number. Thus 8x+4-3 can be simplified to 8x+1. Setting this to 0, we get 8x+1=0 which solves out to x cannot equal -1/8. Thus, x can equal and be greater than -1/8.

I What is the sale price of a stereo that normally sells for $250.00 and is on sale for 10% off?

Aleksandr [31]

Answer:

$225.00

Step-by-step explanation

First, take the percentage and switch it to a decimal. 10%= 0.10

Next, take $250.00 and multiply that by 0.10. 250x0.10=25

Lastly, subtract 25 from 250. 250-25= 225.

So you’re final answer is $225.00 Hope this helped!

A shop has a sale that offers 20% of all prices.

Nana76 [90]

<h2>Greetings!</h2>

Answer:

40% reduction

Step-by-step explanation:

To answert this, we need to find how much of the price is each percentage. This can be found my subtracting the percent from 100:

Sale price: 100 - 20 = 80

Last day price: 100 - 25 = 75

Now we need to multiply these two values together, remembering to divide both numbers by 100 first:

80 ÷ 100 = 0.8

75 ÷ 100 = 0.75

0.8 * 0.75 = 0.6

Then multiply by 100 to find the percentage:

0.6 * 100 = 60

60% is the end price, but to find the overall reduction we need to subtract this value from 100:

100 - 60 = 40

So there was a 40% reduction on the price.

MULTIPLE CHOICE A thermometer is

pav-90 [236]

The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F

Thermometer accuracy = ±2°F
Thermometer reading = 17°F

The least possible value of temperature can be calculated thus :

Thermometer reading - thermometer accuracy

17 - 2 = 15°F

The highest possible temperature can be calculated thus :

Themometer reading - thermometer accuracy

17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
