Answer:
32
Step-by-step explanation:
The unknown side of the shape is 4+6=10
so
3+4+6+9+10=32
Answer:
y= -17x-120.
Step-by-step explanation:
1) according to the condition the lines are parallel. It means the slope of the required line is -17;
2) if to substitute the (-7;-1) into the equation y= -17x+i, then i= -120;
3) the required equation of the line is y= -17x-120.
First, you need to find the mean of all this set of numbers. You would add them all together and then divide by 6 which is 50.5.
Now you find the sample variance. Subtract each number from the mean.
<span>15.5, 13.5, 8.5, -6.5, -10.5, -19.5 </span>
After, you square each value and add them.
<span>240.25+182.25+72.25+42.25+110.25+380.2... </span>
<span>= 1027.5 </span>
Now divide by 5 (because it's a sample variance) and you get 205.5.
Answer:
(2, 4)
Step-by-step explanation:
To solve this system, the easiest way would be to use the substitution method. You can simply plug in, or substitute the value of y from the second equation, which is -x + 6, into the first equation. So you would get:
-x + 6 = 3x - 2
6 = 4x - 2
8 = 4x
2 = x.
To find y, just substitute the value of x, which is 2, into either equation:
y = 3(2) - 2
y = 6 -2
y = 4.
Make sure you write your answer as an ordered pair! So, the final answer is (2, 4). Hope that helped! :)
