Answer:
Negative, positive, 0, undefined
Step-by-step explanation:
A negative slope is when a line is going down from left to right. A positive slope is when a line is going up from left to right. A slope of 0 is a horizontal line and an undefined slope is a vertical line. Hope this helps!
To complete the square (x+2/5)^2 it would be x^2+(4/5)x+4/25
Answer:
associative property
Step-by-step explanation:
So, let's start with the fact that we have two numbers. Let's call one of them "x" and the other one "y." Let's also assume that "y" is the larger number and "x" is the smaller number.
We know that both of them added together (the sum) gives us 74. Mathematically, that means:
x+y=74.
We also know that the larger number ("y") is 4 more than the smaller number ("x"). Another way to say this is, if you have the smaller number and add 4 more to it, you'll end up with the larger number. Mathematically, this means:
y=x+4
Since we know that y=x+4, we can put "x+4" into the first equation for "y", giving us:
x+(x+4)=74
Simplifying gives us:
2x+4=74
-4 -4
---------
2x=70
--- ---
2 2
x=35
Since we now know that x=35, and we know that y=x+4, we now know that:
y=(35)+4
y=39
Now that we have both of the numbers, we should check our work to ensure it's correct:
Does 39+35=74? Yes it does.
Is 39 (the larger of the two numbers) four more than the smallest number (35)? Yes it is.
Count the number of squares for each room. That is the area of each room. Add the area of all the rooms together to get the total area.
