Answer:

  A. 15

  B. -3

  C. x

Step-by-step explanation:

C. Since we want different values of g(f(x)), it is convenient to find that first.

  g(f(x)) = g(2x +9) = ((2x +9) -9)/2 = 2x/2

  g(f(x)) = x

__

A. g(f(15)) = 15

__

B. g(f(-3)) = -3

Answer:

You are correct, it is 20% increase as:

(60/50) - 1 = 0.2 = 20%

Answer:

The number of bleachers seat sold = 200

The number of end zone seats sold =200

The number of excellent seats sold =100

Step-by-step explanation:

Let there are bleachers seats =x

The number of zone seats =y

The number of excellent seats =z

So, we can set up equations for given sentences as

x+y+z= 500

20 x+30 y+40 z=14000

x=y

Substitute x as y into first two equations

y+y+z=500

20 y+30 y+40 z=14000

Simplify each

2 y+z=500

50 y+40 z= 14000

Multiply 2 y +z=500 by -40 to eliminate z terms when we add them.

-80 y-40 z=-20000

Add this with 50 y +40 z=14000, which gives

-30 y=-6000

Divide both sides by -30

y=200

Now, plug in y as 200 into any of the equations to find z.

2(200)+z=500

400+z =500

Subtract both sides 400.

z=100

Now, we know x=y

So, x=200

Answer:

144

Step-by-step explanation:

Since a is 6 and b is 24 we would have to multiply both of those numbers which would give you 144.

Hope this helps and good luck!!

When a = 6 and b = 24, the value of the equation ab will be 144.

Algebra is the study of mathematical symbols, while logic is the manipulation of those signifiers.

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS rule. To answer the problem properly and accurately, this rule should be followed.

The expression is given below.

⇒ ab

If the values of "a" and "b" are 6 and 24, respectively. The expression's value is then provided as,

⇒ a × b

⇒ 6 × 24

⇒ 144

When a = 6 and b = 24, the value of the equation ab will be 144.

Answer:

M = (7,6)

Step-by-step explanation:

formula to find mindpoint is

[tex](\frac{x2 + x1}{2} \frac{y2 + y1}{2} )[/tex]

(4,2) = (x1, y1)

(10,10) = (x2,y2)

now substitute those into the formula!

[tex]\frac{10 + 4}{2} \frac{10 + 2}{2} [/tex]

now solve for x & y !!

[tex]x = \frac{10 + 4}{2} = \frac{14}{2} = 7[/tex]

[tex]y = \frac{10 + 2}{2} = \frac{12}{2} = 6[/tex]

so now that we have solved for x & y put it in point form and your done !!

point for is (x,y)

and thanks why the Midpoint is (7,6)

Answer:

it is -2

Step-by-step explanation:

Answer:

x=7

Step-by-step explanation:

first, add 12 to both sides so it would look like: 6x-12+12=30+12

so, ya get 6x=42

then you divide 6 from both sides, and that is: 6x/6=42/6

so x=7

Answer:

74 adult tickets and 106 children tickets

Step-by-step explanation:

let x be the number of adults tickets sold out

and y the number of chlidrens tickets that sold out for the 7:15 pm show

The equations that determine our problem are

x+y=180

12.50x+8.50y=1826

lets separate x from first equation x=180-y and replace at the second equation

12.50(180-y)+8.50y=1826

12.50*180-12.50y+8.50y=1826

2250-4y=1826

4y=2250-1826

y=424/4=106

so x=180-y=180-106=74

Find the smallest multiple (LCM) stands for of both numbers.

Rewrite the fractions as equivalent fractions with the LCM as the denominator.

Step-by-step explanation:

a) x = 25 tickets

   y = 43.75 - Total cost

   a = admission cost

b/c) 1.25(25)+a=43.75

   31.25+a=43.75

   43.75-31.25=12.50 cost of admission

   12.50+31.25=43.75 total cost at the country fair.

(8,9) and (-2,4)

equation would be y = 1/2x+5
