Answer:
Julie has 6 photos that she wants to rearrange.
Two of them are fixed at the middle position.
=> There are 4 photos left for rearranging.
=> This is the permutation with n = 4, k = 4.
=> The number of ways Julie can arrange the photos:
N = 4 x 3 x 2 x 1 = 24 ways
Hope this helps!

Step-by-step explanation:
the easiest approach with a given point and the slope of the line is the point-slope form :
y - y1 = a(x - x1)
where "a" is the slope, and (x1, y1) is a point on the line.
so, we get
y - -8 = 4(x - -3)
y + 8 = 4(x + 3)
if we need the slope-intercept form
y = ax + b
we now simplify the point-slope form
y + 8 = 4x + 4×3 = 4x + 12
y = 4x + 4

Step-by-step explanation:I don't say you have to mark my ans as brainliest but plz don't forget to thank me if it has really helped you...
Answer:
the first one A the sum of the angles are 10x+10 For the second one B the sum wud be 8x+20
Step-by-step explanation:
you juts add them all together
Consider a and b are two point on line... Slope of line: Xa-Xb/Ya-Yb
Another way.. Consider line of equation: 2y+3x+5=0
Slope= -u/v
U=3 (number before x)
V=2 (number before y)
