Hello from MrBillDoesMath!
Answer:
56
Discussion:
See attachment.
As angle "a" + 93 = 180 (straight line has 180 degrees)
a = 180 -93 - 87
But a triangle also has 180 degrees so
37 + x + 87 = 180 =>
x = 180 - 87 - 37 = 56
Thank you,
MrB

Step-by-step explanation:
I find it hard to believe that you were asked to find the solution to a cubic by any other method than graphing it, which I have given below. Not only that, the numbers are very awkward.
The best you could do I think is equate the two equations after you have looked at the graph.
The x value must satisfy
0.5(x - 4) = 2x^3 - 2x - 3
0.5x - 2 = 2x^3 - 2x - 3
2x^3 + 0.5x - 2x - 3 +2 = 0
3x^3 - 1.5x - 1 = 0
from which you can get y
My calculator gives the solution as
x = 0.5
y = - 1.75
I have corrected the mistake I made doing this. The answer is now correct. The graph shows the original two equations which agrees with the combined equation given above.
<span>9x-6y=3
</span>x -intercepts y = 0, 9x = 3 then x = 1/3
y -intercepts x = 0, -6y = 3 then y = -1/2
answer
x -intercepts (1/3, 0)
y -intercepts (0, -1/2)
40-20 = 20 meaning your answer is The Temperature Changed 20° That Day.
