Answer:
The equation of the line that passes through the points
(1,-6) and (-4,9)
is
y=-3x-3
Point Form:
(2, 4), (1, 1)
Equation Form:
x = 2, y = 4
x = 1, y = 1
Answer: 35
Step-by-step explanation: The third side can be between the smallest side (8 units) and the two sides combined (25 + 8 = 32)
The third side can be anywhere from 8 - 32
That is the combination of 10 over 3, which is calculated as the quotient of factorials:
n!/k!(n-k)!
where n = 10 and k = 3:
= 10!/3!(10 - 3)!
= 10!/3!*7!
= (10*9*8)/(3*2*1)
= 720/6
= 120
therefore there a re 120 possible different groups
Answer:
BC = 10.24
Step-by-step explanation:
You can use the Pythagoras theorem for this question
+ 
= 
a = 8cm
b = ???
c = 13cm
We will solve for B (length BC)
+ =
+ = 
Rearrange for b
= -
= 105
b = 
b = 10.24
