Let's solve your system by elimination.
8x+y=−16;3x−y=5
8x+y=−16
3x−y=5
Add these equations to eliminate y:
11x=−11
Then solve: 11x=−11 for x:
11x=−11
11x
11
=
−11
11
(Divide both sides by 11)
x=−1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
8x+y=−16
Substitute: −1 for x in 8x+y=−16:
(8)(−1)+y=−16
y−8=−16(Simplify both sides of the equation)
y−8+8=−16+8(Add 8 to both sides)
y=−8
Answer:
x=−1 and y=−8
Answer:
The probability that 2 certain people will serve on that committee is 11.11%.
Step-by-step explanation:
Since to make a committee 4 men are chosen out of 6 candidates, to determine what is the probability that 2 certain people will serve on that committee the following calculation must be performed:
4/6 = 2/3
1/3 x 1/3 = X
0.333 x 0.333 = X
0.1111 = X
Therefore, the probability that 2 certain people will serve on that committee is 11.11%.
Answer:
Step-by-step explanation:
±3√2. Recall that 2 actually has two roots, one positive and the other negative.
we know that
In a right triangle we have
two legs and one hypotenuse
Let
a,b -----> the legs of the right triangle
c-----> the hypotenuse of the right triangle (the greater side)
Applying the Pythagoras Theorem
therefore
<u>the answer is</u>
The length of the hypotenuse squared is the length of one leg squared plus the length of another leg squared
