Answer:

a. 1/2

b.

\frac{2\pi}{3}

c.

- \pi

d.

- 3

Step-by-step explanation:

For a function

y = a \cos (bx   -  c) + d

The amplitude is

|a|

The period is

\frac{2\pi}{ |b| }

and the phase shift is

x - c

And d is the vertical shift

Here we have

y =  \frac{1}{2}  \cos(3x + 3\pi)  - 3

The a amplitude is

| \frac{1}{2} |  =  \frac{1}{2}

To find the period, first factor out 3 from the

parenthesis

\frac{1}{2}  \cos(3(x + \pi)  - 3

\frac{1}{2}  \cos(3(x - ( - \pi) )  - 3

To find period, the period is

\frac{2\pi}{3}

The phase shift is c so here the phase shift

is

- \pi

or pi units to the left.

Here the vertical shift is -3

Salutations!

Which of the following terms correctly described the figure below.

The following terms are correctly used to describe the figure:

→ Prism. It is a prism because it has same cross section lines down the length.

→ Rectangular solid. It is a rectangular because solid means "3 dimensional shapes".

Hope I helped :D

PLEASE HELP 20 POINTS<br> solve the system of equations y=-5x-7 and -4x-3y=-1 by substitution.
Ainat [17]

Answer:

Solution: x = -2; y = 3 or (-2, 3)

Step-by-step explanation:

<u>Equation 1:</u>  y = -5x - 7  

<u>Equation 2:</u> -4x - 3y = -1

Substitute the value of y in Equation 1 into the Equation 2:

-4x - 3(-5x - 7)  = -1

-4x +15x + 21 = -1

Combine like terms:

11x + 21 =  - 1

Subtract 21 from both sides:

11x + 21 - 21 =  - 1 - 21

11x = -22

Divide both sides by 11 to solve for x:

11x/11 = -22/11

x = -2

Now that we have the value for x, substitute x = 2 into Equation 2 to solve for y:

-4x - 3y = -1

-4(-2) - 3y = -1

8 - 3y = -1

Subtract 8 from both sides:

8 - 8 - 3y = -1 - 8

-3y = -9

Divide both sides by -3 to solve for y:

-3y/-3 = -9/-3

y = 3

Therefore, the solution to the given systems of linear equations is:

x = -2; y = 3 or (-2, 3)
