<h3>Option - D is ✔ (8)</h3>

\:

<h3 />

Given :

  • f(x) = 5x - 7
  • x = 3

To Find :

  • What is the value of x ?

Calculating the value of x :

\sf :  \implies \:  5x - 7

\sf :  \implies \:  5(3) - 7

\sf :  \implies \:  15 - 7

\bf :  \implies \: 8

Hence,

\implies \boxed{ \bf \:  \therefore \: The \:  value \:  of \:  x \:  is \:  8 \: } \\  \\

30 ounces of water of brand A cost 2

20 ounces of water cost 1.50/20 = 0.075 dollar per ounce

30 ounces of water cost 2/30 = 0.0677 dollar per ounce

Consider the function y = -2-3cos (x+pi). What effect does the -2 have on the basic graph
Elenna [48]

ANSWER

-2 shift the graph of the basic function down by 2 units.

EXPLANATION

The given cosine function is:

y =  - 2 - 3 \cos(x + \pi)

This equation can be rewritten as:

y =  - 3 \cos(x + \pi)  +  - 2

We compare this to

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

The effect d has on the graph is that, it shifts the graph up by d units.

If d is negative the graph shifts down by d units.

Since d=-2, the graph will shift down by 2 units.
