<span>y= 2x-4
y= -x+5
so
</span><span>2x-4 = -x+5
2x +x = 5 +4
3x = 9
x =3
y = 2x-4
y =2(3) - 4
y = 6-4
y = 2
answer: (3,2)</span>
Total outcomes of two rolled dice = 6 x 6 = 36
Possibilities for sum of 6 are 3 + 3, 4 + 2, 2 + 4, 5
+ 1, 1 + 5. So total possibilities for sum of 6 are five.
<span>Hence the probability for the sum of 6 = 5/36</span>
Hi there!
Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.
Step 1) Add 8y to both sides.
Step 2) Divide both sides by 6.
Final Answer -
Hope this helps! :D
In order to estimate the mean, you need to choose a value to represent the number in each category of accidents. It is often convenient to use the middle value of the range.
.. (4*6 +10*10 +15*6 +20*9)/(6 +10 +6 +9) = 394/31 ≈ 12.7
<span>Y=2/3x+3 so slope = 2/3
</span><span>2x-3y=8
3y = 2x - 8
y = 2/3x - 8/3 so slope = 2/3
both equations have same slope = 2/3
so answer: </span><span>parallel</span>
