Answer:
The answer to your question is x = -0.6, y = 0 or (-0.6, 0)
Step-by-step explanation:
Equations
-2x + 3y = 1.2 ------------------ (I)
-3x - 6y = 1.8 ------------------ (II)
Solve equation I for y
3y = 2x + 1.2
y = 2/3x + 1.2/3
Substitute in equation II
-3x - 6(2/3x + 1.2/3) = 1.8
Simplification
-3x - 4x - 2.4 = 1.8
Solve for x
-7x = 1.8 + 2.4
-7x = 4.2
x = 4.2/-7
x = - 0.6
Find the value of y
y = 2/3 (-0.6) + 1.2/3
y = -0.4 + 0.4
y = 0
Answer:
There are 40 outcomes in the sample space for the compound event.
Step-by-step explanation:
The total number of possible outcomes is equal to the product between the number of outcomes for each event.
The coin has 2 possible outcomes.
A twenty-part spinner has 20 possible outcomes (we assume that each part of the spinner corresponds to a unique outcome).
Then the total number of outcomes in the compound event is:
C = 2*20 = 40
There are 40 outcomes in the sample space for the compound event.
Answer:
i8765
Step-by-step explanation:
For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
<span>=> x^4 - 41x^2 + 400 = 0 </span>
<span>=> x^2 = (1/2) [41 ±√(1681 - 100)] </span>
<span>=> x^2 = (1/2) (41 ± 9) </span>
<span>=> x^2 = 16 or 25
</span>
So, therefore, the answers for your problem are
<span>=> x = ± 4 or ± 5.
I hope my answer helped you. </span>
