We know that
slope m=(y2-y1)/(x2-x1)
then
case a) x=18
m=(y2-y1)/(18-18)--------------> is undefined, because <span>the denominator is zero
case b) </span><span>2y-6x=0
2y=6x------------> y=3x
the slope m=3-----------> m is defined
case c) y=9
</span>m=(9-9)/(x2-x1)--------> m=0-----------> m is defined
case d) y=x
m=1---------------> m is defined
the answer is
x=18 has an undefined slope
X=0.037

Answer:
-8
Step-by-step explanation:
It's basically -4-4. Which means -(4+4) = -8.
Answer:
To round a number to the nearest 1000, look at the hundreds digit. If the hundreds digit is 5 or more, round up. If the hundreds digit is 4 or less, round down
Answer: 4 hours
Step-by-step explanation:
First, set up an equation. We know that Bob spent $30 on playing paintball so we use that as our 'answer.' We need to find how many hours Bob played so we need to use x, a variable to find it. We also add 16 because we need to account for the entry fee.
3.50x + 16 = 30
Secondly, solve for x. Move 16 across the equal sign(=). Every time you move across the =, you're going to want to change the sign (if it's addition or subtraction). Since it was +16 and we're moving it, it's now -16.
3.50x = 30 - 16
Calculate 30 - 16 = 14.
Now we have
3.50 x = 14.
To calculate x, we're going to need to divide 3.50 from x. Since we multiplied by x we need to do the opposite across the =.
x = 14 / 3.50
x = 4
Bob spent 4 hours playing paintball.
You can plug it in to check answers as well
3.50 (4) +16 = 30
