Answer:
5
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
-3/10 = (-5--8)/(-5-x)
-3/10 = (-5+8)/(-5-x)
Using cross multiplication
-3 (-5-x) = 10*(-5+8)
Simplify
-3(-5-x) =10(3)
Divide by -3
-3/-3(-5-x) =10(3)/-3
-5-x = -10
Add 5 to each side
-5-x+5 = -10+5
-x=-5
Divide by -1
x=5
Answer:
Total number of arrangements = 1,663,200
Step-by-step explanation:
Given:
11 - letter
FIRECRACKER
F = 1
I = 1
R = 3
E = 2
C = 2
A =1
K = 1
Find:
Total number of arrangements = ?
Computation:
Note: Repeated letter will be avoid.

Total number of arrangements = 1,663,200
Using the distributive property the product is -12x-20. To distribute you take the numbers and or variables outside of the paranthesis and multiply it by each one in the parenthesis such that 4x is multiplied by -3x getting -12x and multiplying 4x by -5 and the product is -20x and all together the answer is -12x-20
Answer:
The true options are:
2) Has exactly one pair of parallel sides
4) Has exactly one pair of congruent sides
5) Both pairs of opposite sides are congruent
7) There are right angles at all 4 vertices
9) The diagonals are congruent
10) The diagonals bisect each other.
