Mathematics

Answer:

f(g(7)) = 22

Step-by-step explanation:

First find the general form of the new equation, f(g(x)):

f(x)=3x + 2

g(x)=x - 1/3

f(g(x)) = 3(x - 1/3) + 2

You can simplify that, or alternatively just plug in 7 now and solve:

f(g(7)) = 3(7 - 1/3) + 2

f(g(7)) = 3(20/3) + 2

f(g(7)) = 20 + 2

f(g(7)) = 22

A theme park had 1099 visitors in 3 days.There were twice as many visitors on saturday than on Friday.There were 234 more visito
Blababa [14]

Answer: there were 692 visitors on Saturday.

Step-by-step explanation:

Let x represent the number of visitors that were there on Friday.

Let y represent the number of visitors that were there on Saturday.

Let z represent the number of visitors that were there on Sunday.

The theme park had 1099 visitors in 3 days. It means that

x + y + z = 1099- - - - - - - - - - - - - -1

There were twice as many visitors on saturday than on Friday. This means that

y = 2x

x = y/2

There were 234 more visitors on Sunday than on Saturday. This means that

z = y + 234

Substituting x = y/2 and z = y + 234 into equation 1, it becomes

y/2 + y + y + 234 = 1099

Cross multiplying by 2, it becomes

y + 2y + 2y + 468 = 2198

5y = 2198 - 468

5y = 1730

x = 1730/5

x = 346

y = 2x = 2 × 346

y = 692

z = y + 234 = 692 + 234

z = 926

Solve for x please for 10 points
Ira Lisetskai [31]

Answer:

\frac{x-2}{2+1}=\frac{4x-5}{3}

\frac{x-2}{3} =\frac{4x-5}{3}

3*\frac{x-2}{3} =\frac{4x-5}{3}*3

x-2=4x-5

x-2+5=4x-5+5

x-x+3=4x-x

3=3x

\frac{3}{3} =\frac{3x}{3}

1=x

Step-by-step explanation:

your answer is B

Find the equation of the cosine graphed.
Lunna [17]

Answer:

C) y = -cos(x) +2

Step-by-step explanation:

The centerline is 2, so 2 is added. That leaves out choices A and B.

There is a minimum (not a maximum) at x=0, so the multiplier is negative, eliminating choice D.

The correct equation is that of C: y = -cos(x) +2.
