Well lets look at each
A. symetric property is if a=b then b=a
this is not the answer

B. aditive inverse is adding the inverse so
that would be x+(-x)=0 which is not this one

C. additive identity property, the identity stays the same if you add 0
so x+0=x
this is the answer

D. opposite of a sum property, this is adding a negative or
x-y=x+(-y)


the answer is C

Find the probability of drawing a face card or a 3 from a standard deck of cards.
Mrrafil [7]

There are of course 52 cards in the standard deck. A face card is a jack, queen or king, and each comes in four suits, so 12 face cards. 

Four 3s mean 16 cards of 52 satisfy our event.

p = \dfrac{16}{52} = \dfrac{4}{13}

He base of a pentagonal prism has an area of 2.4 m2. The prism has a volume of 4.8 m3. What is its height? Use sketches, formula
77julia77 [94]

Answer:

The height of the prism is 2m

Step-by-step explanation:

Given;

The volume of pentagonal prism, V = 4.8 m^3

Area of the prism, A = 2.4 m^2

To determine the height of the prism, we consider the following;

Volume of any prism = Area of the prism x height of the prism

Height of the prism = volume of the prism / Area of the prism

Height of the prism = 4.8 / 2.4

Height of the prism = 2 m

Therefore, the height of the prism is 2m

Help ASAP please thanks
andrew-mc [135]

Answer:

#1: -2 ≤ y ≤ ∞

#2: -2 ≤ x ≤ 2

#3: -4 ≤ y ≤ 3

#4: -5 ≤ y ≤ ∞

#5: 0 ≤ x ≤ ∞

Step-by-step explanation:

To do these, you must understand what range and domain are:

Range: all the values that y can be

Domain: all the values that x can be

#1: It's asking for range, so look at the posible y values. The smallest y value is -2, and the largest is actually infinity. So, the range is: -2 ≤ y ≤ ∞.

#2: It's asking for domain, so look at the possible x values. The smallest is -2 and the largest is 2, so: -2 ≤ x ≤ 2.

#3: Again, it's asking for range, so look at the possible y values. The smallest is -4, and the largest is 3, so: -4 ≤ y ≤ 3.

#4: It's asking for range. The smallest value is -5, and the largest goes to infinity (from the arrows), so: -5 ≤ y ≤ ∞.

#5: It's asking for domain. The smallest x value is 0, and it goes to infinity. So: 0 ≤ x ≤ ∞.
