If a function is even, it gives the same result for positive and negative inputs such as 8 and -8.
<em>From the choices, the even functions are D and A.</em>
D because the absolute value thing makes any input positive, and A because any number raised to an even power gives a positive result.
<span>You first need to find the area of the living room.
Both of the two stores are dealing with square yard. The first thing you need to do is convert your feet to yards.
There are 3 feet in 1 yard. So divide the number of feet by 3 to get the yards.
12/3 = 4 yards
19/3 = 6.333 yards.
You then multiple those numbers to get your square yardage of the room (i.e. your area)
4*6.333 = 25.33333 sq. yards.
Now, look at what the first store is offering. You need to calculate the price. Originally, the carpet will cost $18 the number of square yardage for the carpet ONLY. So, multiple
$18 by your area of 25.33
18*25.333 = $456
Now, there is a sale of 20% off the carpet only price. You know the price so you need to take 20% of that and then subtract that number from the original total. Think of it like this. If you went and something was 50% off, and it was originally $10. 1/2 of 10 is 5. 10-5 is 5. That's the price you would pay. Use the same process with this problem.
$456*.20 = 91.20
(remember a % is the same as moving the decimal over 2 places.)
Take 91.20 off of 456
456-91.20 = 364.80
Then, find the installation price. They say that they will charge $2 per square yard. Your square yardage is 25.333. Now multiple those two numbers.
2*25.333=50.66
Add that price to the 364.80 to get the TOTAL for the first store.
364.80+50.66=415.47 (rounded off from 415.466)
Cindy's carpet:
they have $18 per square yard. Again, multiple 18 by your square yardage.
18*25.333 = 455.99
If it is 10% off, you go through the same process as before.
455.99*.10=45.59
Subtract that from the whole
455.99-45.59 = 410.40 </span>
The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x.
we can suggest the following equation:
3x+4x+5x=180
12x=180
x=180/12
x=15
The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75
Answer: the highest angle would measure 75º.
Answer:
p=2
Step-by-step explanation:
10 – (8p + 3) = 9(2p - 5)
(rearrange and distribute) -8+7=18−45
(Subtract and combine) −26=−52
(Divide and find p) p=2
Answer:
Slope = 3
Step-by-step explanation:
Because it increases by 3 each time.
