Answer:
No (1,8) is not a solution to 19x+3y=2.
However, (1,8) is a solution to 3x+y=11.
Step-by-step explanation:
(1,8)
The one represents the x shown in each equation, the eight represents the y.
Substitute the one in for the x and the eight in for the y.
19x+3y=2
19(1)+3(8)
3x+y=11
3(1)+(8)
Next, solve the equation.
19(1)+3(8) = 43
3(1)+(8) = 11
As you can see, 43 does not equal 2.
But, 11 does equal 11.
Divide the numerator and denominator by 5 and get 1/12
so 5/60 simplified is 1/12
Hope this helps! :D
Given:
<span>The average number of daylight hours each month in Springfield in 2015:
Jan 9.5
Feb 10.5
Mar 12
Apr 13.25
May 14.5
Jun 15
Jul 14.75
Aug 13.75
Sep 12.5
Oct 11.0
Nov 9.75
Dec 9.25
Now, we observe the trend of the monthly hours, it starts with a low value then increases and decreases back to the original value. This represents a parabola with the highest point of 15 hours. </span><span />
