<span>1. Solve the system by substitution -2x+y=-11, 3x-4y=11. 
</span>-2x+y=-11<span>
y = 2x-11

</span><span>3x-4y=11
</span>3x-4(2x-11)=11
3x -8x + 44 = 11
-5x = -33
<span>x =33/5
y = 11/5

</span><span>2. Solve the system using elimination- 2x+6y=-12, 5x-5y=10. 
</span><span>(-2x+6y=-12)5
</span>-10x + 30y = -60

<span>(5x-5y=10)2
</span>10x - 10y = 20

Adding the two equations,
<span>-10x + 30y = -60
</span><span>10x - 10y = 20
</span>
20y = -40
y = -2
x = 0

<span>3. What is the solution of the following system?-3x-2y=-12, 9x+6y=-9. 
</span><span>-3x-2y=-12
</span>y = -3/2 x + 6

<span>9x+6y=-9
</span>y = -3/2 x - 3/2

Since the slopes are equal then they are parallel lines so they never meet at one point.

Suppose the odds against winning the lottery as 48,000,000 to 1. What is the probability of the event of winning the lottery giv
kupik [55]

The probability according to the given scenario will be "\frac{1}{48,000,001}".

According to the question:

  • The odds against winning the lottery are 48,000,000 to 1.
  • Favorable outcome = 1

→ The total outcome will be:

= 48,000,000 +1

= 48,000,001

As we know,

→ P(E) = \frac{Favorable \ outcomes}{Total \ outcomes}

By putting the values, we get

→           =\frac{1}{48,000,001}

Thus the above response is right.

16 ÷ 22 + (6 x 2) - 8
stepladder [879]
I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72
