There's another way to do this, but I'm showing you what I use.
First: I would go ahead and subtract 9x from both sides of the equation. By doing that, the "9x" on the left side would cancel out and you would be left with "7=-6x-5"
Second: Add 5 to both sides of the equation. It should cancel out the 5 on the right and you should be left with "12=-6x"
Lastly: Divide both sides by -6, the -6 on the right next to the variable will cancel out and you'll be left with "-2=x" Which is the solution.
Answer:
x = -20
y = -62
Step-by-step explanation:
Suppose x and y two number and such that :
- their sum = -102
- and y is 62 less than x
Which means :
then
then
x + y = (y+62) + y = -102
then
2y + 62 = -102
then
2y = -164
then
y = -164/2 = -82
therefore
x = y + 62 = -82 + 62 = -20
That is true as the collision impact is a combination of weight and velocity.
Answer:
2. 4th degree polynomial
Step-by-step explanation:
The degree is the highest exponent in the expression. Since the highest exponent is 4, this is a 4th degree polynomial.
