1. we can add them to eliminate y's
3x-4y=-16
<u>-x+4y=24 +</u>
2x+0y=8
2x=8
divide by 2
x=4
sub back
-x+4y=24
-4+4y=24
add 4 both sides
4y=28
divide by 4
y=7
(x,y)
(4,7)
3.
add them to eliminate y's
-5x+3y=12
<u>-2x-3y=-33 +</u>
-7x+0y=-21
-7x=-21
divide both sides by -7
x=3
sub back
-2x-3y=-33
-6-3y=-33
add 6 to both sides
-3y=-27
divide both sides by -3
y=9
(x,y)
(3,9)
1. (4,7)
3. (3,9)
Answer:
(-2,3)
Step-by-step explanation:
The answer from the question above is the following.
The mean is the sum of observations divided by the number of observations.
The Mode is the observation that occurs frequently.
Lastly, the median is a value of middle observation if an uneven number of observations or the average of the two middle if the even number of observations.
5+9=14 and 15-8=7
14÷7=2
hope this helps :)
First: (X+3)(x+3) foil it.
Then distribute the 3x among the values and combine like terms
