<span>Hello : let
A(2,-1) B(8,4)
the slope is : (YB - YA)/(XB -XA)
(4+1)/(8-2) = 5/6</span>
<span>an equation for the line in point-slope form is : y-(-1) =( 5/6)(x-2)
y+1 = (5/6)x -5/3
6y+6 = 5x -10
</span><span>the equation in standard form is : 5x-6y = 16</span>
Hey there! I'm happy to help!
A permutation is focused on a specific order, while a combination is not focused on the order but on the content of what is grouped.
AB and BA are different permutations because they are in different orders, but they are the same combination because they both contain the letters A and B.
So, we see that AB and BA are one combination.
AC and CA are also another combination because they are made up of the letters A and C.
Same goes for BC and CB, this is also one combinations.
This totals up to C. 3 combinations. Now you know the difference between permutations and combinations!
Have a wonderful day!
Answer: i think the answer is 1
Step-by-step explanation:
<h3>
Answer: 64 cm^2</h3>
Reason:
The parallelogram has area of A = base*height = 10*7 = 70 cm^2
The white rectangle has area of B = base*height = 3*2 = 6 cm^2
The shaded region has area of A - B = 70 - 6 = 64 cm^2
If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.
