Answer: 8.99mm
Step-by-step explanation:
a^2 + b^2 = c^2
Since you did hours instead of minutes it would be 5.15
If you were asking for minutes it is 315.
Answer:
Step-by-step explanation:
Easiest way would be to substitute points into the given equations and plot your answers.
E.g. if you substitute points into your first equation you get:
If x = 0, y = -4(0) +2 = 2
If x = 1, y = -4(1) +2 = -2
If x = -1, y = -4(-1) +2 = 6
Etc.
Second equation:
If x = 0, y= -(0) -1 = -1
If x = 1, y = -1 -1 = -2
If x = -1, y = -(-1) -1 = 0
Pretty much just plug in values for x into the equations to find y.
Once you have your points, draw a line :)
Where the two lines intercept would be the solution.
Basically just add them all together like normal addition except there is a z attached to each number:
43z + 15z + 7z + 5z + 46z + 14z
58z+ 7z + 5z + 46z + 14z
65z + 5z + 46z + 14z
70z + 46z + 14z
116z + 14z
130z
Hope this helped!
