Answer:

Step-by-step explanation:
Let v be the speed after the collision of both the cars.
Now, momentum is given by: mass × velocity, then by equating the total momentum before and after the collision of the two cars, we get

⇒
⇒
⇒
Thus, they are moving at the velocity of 
The starting salary is $35,000.
Salary is increased by 6% at the end of every year.
Nos of years worked = 16 years
Total salary earned in 16 years is given by An * (( 1+i )^n - 1 ) / i
Where, An = Present Salary = $35000
i = Increase in salary per year = 6% = 0.06
n = number of years = 16
= 35000 * ( 1.06 ^16 - 1 ) / .06
= 35000 * ( 2.54035 - 1 ) / .06
= 35000 * 1.54035 / .06
= 898538
Total earnings in 16 years is $ 898538
For this equation we are factoring. When you do this. You get the answer of:
(-3x²+8x-7)
Ok fist you wanna change your question into a equation so it would turn into x-6 y=4 and 4.3x - 18 y = 4 then multiple both sides and that pups give you 43x - 180 y = 40 and eliminate one variable and I don’t wanna keep explaining but the the answer is
ANSWER: (x , y ) = (- 80 over 13, and - 22 over 13
