select the correct answer and show your work so what property is illustrated by 18 x 0=0 is it a. zero property b. property of o
juin [17]
It is a, the zero property.  It is so since you are multiplying zero to get an answer of zero.
I will try to elaborate.

The "Zero Product Property" says that:

If   a × b = 0   then   a = 0   or   b = 0   
(or both a=0 and b=0)

18 x 0 = 0

Let's say that 18 = a and 0 = b.  By the converse of the statement, it states that if a or b is zero, then it must be the zero property.  Since b is in fact, zero, then we can conclude that it is, in fact, the zero property.

Jimmy's school is selling tickets to the annual dance
LiRa [457]
A= adult ticket c=child ticket
1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)
hoped this helped:)

The coordinates of DEF are D(3,4), E(6,4), and F(5,9). If you translate DEF 3 units left and 2 units up, what are the coordinate
grigory [225]

EXPLANATION:

1.We must locate the points that the exercise gives us in the Cartesian plane.

2.The figure that it gives us must be moved 3 units to the left and then 2 units up.

3.To correctly translate a figure, we must add the units that the exercise indicates and towards the correct direction, if it tells us that to the left is towards the negative axis, then each of the points given in the exercise we will transfer 3 units towards the left and then add each of the points two units up, then we see that the triangle takes new coordinates for the points.

4.The new coordinates for point E are (3,6)
