cos (arctan (1))=

arctan (1) = 45   take it to the third quadrant = add 180  = 225

cos (225) = -1 / sqrt(2)

            never leave a sqrt in the denominator

     = -1 /sqrt(2) * sqrt(2)/sqrt(2)

   = -sqrt(2)/2


sin (arccos (1/2)

arccos (1/2) = 60    take it to the 4th quadrant   -60 degrees

sin (-60)

- sin 60

- sqrt(3)/2

Answer:

(5,38)

Step-by-step explanation:

<u><em>The correct question is</em></u>

A system of equations is shown below:

y = 8x − 2

y = 9x − 7

What is the solution to the system of equations?

(−5, 38)

(−5, −38)

(5, 38)

(5, −38)

we have

y=8x-2 ----> equation A

y=9x-7 ----> equation B

Solve the system by substitution

substitute equation B in equation A

9x-7=8x-2

solve for x

9x-8x=7-2

x=5

<em>Find the value of y</em>

Substitute the value of x in the equation A or in the equation B

y=8(5)-2=38

therefore

The solution is the point (5,38)
