Find the accelartion: a man starts walking up a hill, initially he is moving at 6m/s, but as he approaches the top of the hill after 5 minutes, his speed is only 2m/s. what was his acceleration? a car is travelling east for 300km.   it takes 45 minutes. what is the car’s velocity in m/s? (don’t forget direction). show all work!

answer: ff

f

step-by-step explanation: f

ff

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
