I'm assuming this is set equal to zero (just to make things easy). Then you have
The first equation has no solution, since
is always positive.
Meanwhile,
That is a 45 degree angle on the side
Answer:
0.875 is the equivalent fraction
76.9
For rounding, any number 5 and up rounds up and any number below 5 rounds down
Also, numbers in the decimal start with tenth, hundredth and so on
x (3-5) + (4b)
= x ( -2) + (4b), since x=8 b=3
= -16 + 12
= -4
What I did there is substitution
Replacing x with 8 ,and b with 3
So -16 is the product of (-2) and 8
And 12 is the product of 4 and 3
FYI: -2 is the result of 3 - 5
