1. combine like terms (2x and -7x) to create -5x
2. subtract 5 from each side to create: -5x=10
3. divide both sides by -5
4. x=-2
The x intercepts occur when you set the factors equal to 0. x+1=0 & x-6=0 gives you the x-intercepts. x+1=0 -> x=-1. x-6=0 -> x=6. Therefore, -1 & 6 are your x intercepts
To find a median of an even amount of numbers, add the two middle numbers, and divide by two.
45 + 46 = 91
91/2 = 45.5
45.5 is your median
hope this helps
We have that
10 mm is equal to -------> 1 cm----> multiply by 100
10*100 mm is equal to -------> 1*100 cm
1000 mm is equal to -------> 100 cm
and
we know that
100 cm is equal to-------> 1 m
therefore
1000 mm is equal to -------> 100 cm
100 cm is equal to-------> 1 m
1000 mm is equal to--------> 1 m
X mm-----------------> 7.5 m
x-7.5*1000-----> x=7500 mm
the answer is
7500 mm
