General equation of a cosine function: y = acos(cx), where a is the amplitude and \frac{2\pi}{c} is the period.

Hence, a = 2 and \frac{2\pi}{c} = 4\pi; c = \frac{1}{2}

Thus, the equation is y = 2cos(\frac{\pi}{2})

Step-by-step explanation:

1.

Find value of P that makes this true

4p-5=`9

Solve for P by isolating it on one side:

4p-5+5=9+5

4p/4=14/4

P=3.5

2.

Translate the Algebraic Expression:

A waiter earns $128 for 6 hours of work including $86 of tips.

Subtract tips from total:

128-86=42

Divide Value between hours.

42/6=7

$7 per hour

3.

Find the Value of X that makes this true

-4x+26=-2

Solve for X by isolating it on one side:

-4x+26-26=-2-26

-4x/-4=-28/-4

X=7

4.

What is the first correct step in solving the equation:

33-2x=31

Subtract 33 from both sides

Determine whether each statement about the system of the two linear equations is true or false:
Ostrovityanka [42]

Answer:

1 is false

2 is true

3 is false

4 is false

Step-by-step explanation:

y-33=-2

y-33+32=-2+33

y=31

31=3x-2

31+2=3x-2+2

33=3x

33/3=3x/3

11=x

solution is (11,31)

graph of y=-3x-2... y=31 would be a horizontal line on 33 at the y axis
