Answer:
Your answer is C.) x2(x – 2) cubic units
On EDG
Step-by-step explanation:
Just took the test
<span>Solve the system
9x = 27-9y
20x=71-9y
Let's use the "elimination through addition/subtraction method.
Multiply the first equation by -1 so as to obtain +9y:
-9x = -27 + 9y
</span><span>20x= 71- 9y
--------------------
Add these 2 equations together:
</span>-9x = -27 + 9y
20x= 71- 9y
--------------------
<span> 11x = 44
Solve this for x: x = 44/11 = 4.
Now find y by subst. 4 for x in either of the original equations.
Using the second equation: </span><span>
</span>20x=71-9y
20(4) = 71 - 9y
80-71 = -9y
9 = -9y. Then y = -1.
The solution set is (4,-1).
Answer:
probability of bag one 62.5% for blue marbles green- 37.5%
probability of bag 2 66.67% for yellow and for blue 33.33%
he will probably get a blue and yellow marble
:)
A and D
To get x on one side you have to, in this case, add 3 to both sides. This is the addition property of equality
