The answer is (1,-4)
Remember that the vertex is the center of the parabola.
6/9 and 12/21
i think this is the answer your looking for
3x - 5y = 18 over
-10x + 5y = 10
Add them because the 5y's have the right symbols for us to add
-7x = 28
Divide
x = -4
Now you can plug in -4 for x in one equation, I would use the first equation!
3(-4) - 5y = 18
-12 - 5y = 18
Add 12
-5y = 30
Divide
y = -6
Your solutions are going to be:
x = -4
y = -6
To check your work plug x and y into one equation:
3(-4) - 5(-6) = 18
-12 + 30 = 18
18 = 18
Since 18 does equal 18 you know that your solution's work!
In 24 hour time format, afternoon time 1300 is 1pm, 1400 is 2pm, and in general we have to subtract 1200 to make the pm times traditional.
2250 - 1200 = 1050, ten to eleven.
Choice b.
200÷P, as you need to to do the equivalent of 20-p-p-p... until you get to 0, which is faster and more simply done with division.
