Answer:
x = 6.39, y = 1.69 is the solution of the given equation system.
Step-by-step explanation:
Here, the given set of equation is:
5 x = 15 + 10 y ⇒ 5 x - 10 y = 15 ...... (1)
3 x +7 y = 31 ............. (2)
Now, the coefficient of x in first equation id 5 and in second is 3.
So, MULTIPLY (1) with 3 and (2) with -5 , we get:
15 x - 30 y = 45
-15 x- 35 y = -155
<u>ADD BOTH EQUATIONS ,</u> we get:
15 x - 30 y -15 x- 35 y = 45 - 155
or, -65 y = -110
or, y = 110/65 = 1.69
Put y = 1.69 in 3 x +7 y = 31 , we get:
3(x) + 7 (1.69) =31
⇒ 3 x = 19.17 or x = 6.39
Hence, x = 6.39, y = 1.69 is the solution of the given equation system
Range:$43.25-$36.50=$6.75
Mean:$42.95+$36.50+$40.75+$38.25+$43.25=$201.7
Median:$40.75
Mode:none
The range is $6.75. The mean is $201.70. The median is $40.75. There is no mode.
Answer:
Slope-intercept form is
y = mx + b
We want to get the y by itself on one side of the equation.
0 = 18x + 6y – 2
First let's subtract 6y from both sides.
-6y = 18x – 2
Next let's divide both sides by -6.
y = (18 / -6)x - (2 / -6)
y = -3x + 1/3
...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)
