root 30 ..................
Answer: B
Step-by-step explanation:
y = mx + mc
The perpendicular will have slope -1/m and intercept mc, which is
y = (-1/m)x + mc
For the answers you have to factor out a -1/m from both terms:
Answer:
k = 10
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
115 = (4k+5) + (6k+10)
Combine like terms
115 = 10k+15
Subtract 15 from each side
115-15 = 10k +15-15
100 = 10k
Divide by 10
100/10 = 10k/10
10 =k
We need to compute for the length of each trophy given that one trophy is 5 inches wider than the other.
Let x be the length of the first trophy.
Let x+5 be the length of the second trophy
The solution is shown below:
x + (x + 5) = 17
x + x + 5 =17
2x =17 -5
2x = 12
x = 12/2
x=6 (for the first trophy)
x + 5 = 6+5 = 11 (for the second trophy)
The first trophy is 6 inches wide while the second trophy is 11 inches wide.
