Answer:

a and f

Step-by-step explanation:

a. x + 3 = 5x - 4

x - 5x = -4 - 3

-4x = -7

x = -7/-4

x = 7/4

b. x - 3 = 5x + 4

x - 5x = 4 - 3

-4x = 1

x = -1/4

c. 2x + 8 = 5x - 3

2x - 5x = -3 - 8

-3x = -11

x = -11/-3

x = 11/3

d. 10x + 6 = 2x - 8

10x - 2x = -8 - 6

8x = -14

x = -14/8

e. 10x - 8 = 2x + 6

10x - 2x = 6 + 8

8x = 14

x = 14/8

f. 0.3 + x/10 = 1/2x - 0.4

3/10 + x/10 = 1/2x - 4/10

x/10 - 1/2x = -3/10 - 4/10

x/10 - 5/10x = -7/10

-4x/10 = -7/10

-4x = -7

x = -7/-4

x = 7/4

The graph of the function is of the form<br> f(x) = a * sin(kc – c) + h.
Brut [27]
The answer is : f(x) =3sin(2x+pi/2)

Explain

There 0,3 on the graph

You use this formula

f(x)=asin(kx-c)+h

and the maximum and minimum value of this function

a+ h and -a+ h

So a=3 and h=0

So we have

We have; f(x)= 3sin(kx - c)
and we have from the graph;

f(O)=3

So

Sin(-c) =-1

Therefore C=. Pi/ 2 +2pi n

We have period of the function is pi


2pi/ k
k=2
So it will equal Pi


Do you have any doubts ?

Kamila buys a notebook for $1.59 and pens for $0.29 each. She spends $5.07.
emmasim [6.3K]

Answer:

12 pens

Step-by-step explanation:

Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.

Price of a notebook = $1.59

Price a pen = $0.29

Total amount spent = $5.07

But,

1.59 + 0.29 n = 5.07

So that,

0.29 n = 5.07 - 1.59

0.29 n  = 3.48

n = \frac{3.48}{0.29}

  = 12

Therefore, Kamila bought 12 pens.
