2.8 ! the two is the whole and the fraction is the 8 after the decimal ! happy learning!
Answer:
-8 = x
Step-by-step explanation:
-15 = 2x + 1
-1 - 1 Subtract 1 from both sides
-16 = 2x Divide both sides by 2
-8 = x
To make sure this answer is correct, plug it into the equation to see if it works.
-15 = 2(-8) + 1 Multiply
-15 = -16 + 1 Add
-15 = -15
Remark
Now we have to get two more zeros from somewhere. Let us say that the last factor is x^2 + 4 which gives a pair of complex answers. The complete quartic could be something like
y = (x + 4)(x + 1)(x^2 + 4)
The graph follows.
One pound is equal to 0.453592 kilograms.
So 3* 0.453592=1.360776 kg
