Third question I'm giving 50 points ​
marishachu [46]

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:

$y = -\frac 1m x + mc \cdot -m \cdot -\frac 1m$\\

$y = -\frac 1m (x + mc \cdot -m)$

$\boxed{\;\textbf{(B)}\ \,y = -\frac 1m (x - m^2 c)\;}$

Anyone know the answer???
Umnica [9.8K]

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

a bookshelf is 17 inches wide. there is enough room for 2 trophies. one trophy is 5 inches wider than the other. how wide is eac
kicyunya [14]
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.
