From a boat on the lake, the angle of elevation to the top of a cliff is 26°1'. If the base of the cliff is 205 feet from the bo

First off hmm <span>26°1' is just 26 degrees and 1 minute

there are 60 minutes in 1 degree, so 1minute is just 1/60 degrees
so </span>26°1' is 26° + (1/60)° or 26.1667 rounded up, since 1/60 is a recurring unit

alrite... so hmm, check the picture below

make sure your calculator is in Degree mode.

4-7x=1-6x can someone please solve and show the work :)

Answer:

x = 3

Step-by-step explanation:

Simplifying

4 + -7x = 1 + -6x

Solving

4 + -7x = 1 + -6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6x' to each side of the equation.

4 + -7x + 6x = 1 + -6x + 6x

Combine like terms: -7x + 6x = -1x

4 + -1x = 1 + -6x + 6x

Combine like terms: -6x + 6x = 0

4 + -1x = 1 + 0

4 + -1x = 1

Add '-4' to each side of the equation.

4 + -4 + -1x = 1 + -4

Combine like terms: 4 + -4 = 0

0 + -1x = 1 + -4

-1x = 1 + -4

Combine like terms: 1 + -4 = -3

-1x = -3

Divide each side by '-1'.

x = 3

Simplifying

x = 3

Rewrite y + 3 = 0 using function notation.

liubo4ka [24]

First rewrite as y = ..., just move the +3 to the other side (sign flips):

y = -3.

Then replace y by f(x):

f(x) = -3.

This is a straight line at y=-3.

Answer B.
