A polynomial can only have one constant, since the constant is the one number being added or subtracted from the rest of the polynomial, and it is the only number that is not being multiplied by an x value.
Answer:
1/2
Step-by-step explanation:
So lets go over what slope is.
The formula for slope is y/x
To find this, we can just count the change in y, and put it over x.
So lets see.
On the graph, we can count that y goes up by one, and that x goes to the right by 2.
So this means our slope is y/x, or 1/2.
This is our answer.
I hope this helps! :)
I included a visual of this as well!
Let <em>a</em> be the number in the 10s place and <em>b</em> in the 1s place. Then the original two-digit number is 10<em>a</em> + <em>b</em>.
The sum of the digits is 5:
<em>a</em> + <em>b</em> = 5
Subtract 9 from the original number, and we get the same number with its digits reversed:
(10<em>a</em> + <em>b</em>) - 9 = 10<em>b</em> + <em>a</em>
Simplifying this equation gives
9<em>a</em> - 9<em>b</em> = 9
or
<em>a</em> - <em>b</em> = 1
Add this to the first equation above:
(<em>a</em> + <em>b</em>) + (<em>a</em> - <em>b</em>) = 5 + 1
2<em>a</em> = 6
<em>a</em> = 3
Then
3 - <em>b</em> = 1
<em>b</em> = 2
So the original number is 32. Just to check, we have 3 + 2 = 5, and 32 - 9 = 23.
The point is located in quadrant I
Answer:
Surface area means all of the outside areas, kind of like when you wrap a present.
Step-by-step explanation:
1st draw the box and find the area of the top and the bottom of the figure
10 x 3 = 30 for the top and 30 for the bottom, so 60 for both.
2nd find the area of two opposite sides:
10x 4.5 = 45 for one side and 45 for the other side, which is 90 for both
3rd find the area of the last two opposite sides:
3 x 4.5 = 13.5 for one side and 13.5 for the other side, so 27 for both.
4th: now add all those sides 60 + 90 + 27 = 177 inches squared.
