Answer: the slope is 2/3.
Step-by-step explanation: The expression for finding slope when given 2 coordinates of the line is (y2 - y1) ÷ (x2 - x1) which just means that you take the y output of the second coordinate given to you and subtract the y output of the first coordinate given from that and the same for the x inputs. So when you plug in the numbers into that expression, you get (0- (-4)) ÷ (9 - 3). When you subract something from a negative number, its the same as adding. So it could also be written as (0 + 4) ÷ (9 - 3). When you subtract and add the numbers in both parentheses you end up with the fraction 4/6, but now you need to simplify that fraction which leaves you with the final answer of the fraction 2/3!
I hope this helps :)
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
There are 720 total different combinations, and 24 of those will have the letters DAY consecutively within all those combinations.
<u>Explanation:</u>
FRIDAY is a six letter word.
To form all combinations of letters, we would have six choices of letters to fill the first spot. Whatever letter you choose for the first spot, you then have five choices of letters to fill the second spot. Four choices of letters to fill the third spot. And so on.
So, the total number of different combinations of the six letters would be 6!
6! = 6 X 5 X 4 X 3 X 2 X 1
= 720
DAY could appear consecutively starting in 4 different spots: the 1st, 2nd, 3rd, and 4th spots of all combinations. DAY will appear consecutively 6 times in each of those 4 starting spots.
6 X 4 = 24.
So, there are 720 total different combinations, and 24 of those will have the letters DAY consecutively within all those combinations.
$6 ? 5+4 =9
9-3 =6
I don't know if this is correct but this is how I would do it
C) y= 7.5x-2
7.5 is a positive slope, and -2 will be your negative y intercept
y=mx+b
Remember m always means slope and b is always the y intercept!
