Answer:

B. 137

Step-by-step explanation:

Assuming by 4x2 you meant 4x^{2}, you plug in the 6 into x.

After, you would square 6, giving you 36.

Then you multiply 36 by 4, getting 144

All that's left to do is subtract 7 from 144 and ending with 137.

Answer:

Step-by-step explanation:

Constant of proportionality (k) = y/x

We can use the coordinates of any point on the line to find k.

Let's use (2, 8)

Constant of proportionality (k) = 8/2

Constant of proportionality (k) = 4

If anyone can solve this quickly I will give brainly

Answer:

m∠BFE  = 171º

BE = 219º

Step-by-step explanation:

∠BFE is supplementary to ∠EFC

m∠BFE  = 180 - 9

m∠BFE  = 171º

--------------------------

The angle between two chords is equal to half the sum of the intercepted arcs:

∠BFE = (DC + BE)2

171 = (123 + BE)/2

342 = 123 + BE

219º = BE
