Answer:

x/2.

Step-by-step explanation:

We replace the x in g(x) by f(x):

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

= (x + 2)/2 - 1

= (x + 2 - 2)/2

= x/2.

Answer:

x/2

Step-by-step explanation:

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

         = [tex]\frac{x+2}{2}[/tex] - [tex]\frac{2}{2}[/tex]

          = (x + 2 - 2) / 2

           = x/2

Part of incomplete work = 2/3 of project

Step-by-step explanation:

Given:

Part of work completed = 1/3 of project

Find:

Part of incomplete work

Computation:

Part of incomplete work = 1 - Part of work completed

Part of incomplete work = 1 - 1/3

Part of incomplete work = 2/3 of project

Answer:

3 * 10^4

Step-by-step explanation:

Here, we want to make a division

We want to divide 9 * 10^2 by 3 * 10^-2

That would be;

(9 * 10^2)/(3 * 10^-2)

= 9/3 * 10^2-(-2)

= 3 * 10^4

Answer and explanation:

Profit from sale of model boats = Sales -costs(costs of goods purchases + expenses or charges by the local fair)

John's profit from the sale of model boats can be represented by the equation:

P= 50x-(5x+80)

Where P is profit from the sale of the model boats and x is number of model boats bought and sold. The 80 is constant as it is a fixed cost paid to the local fair.

For example if John buys and sells 20 model boats, he would make profit of:

Substitute x=20 in equation above

P= 50×20-(5×20+80)

P=1000-180

P=$820

It could be said that John is in a very profitable business and his profit is also dependent on volume of sales because the lower his sales the closer he gets to making a loss and not profit

Answer:

The area of the shaded figure is:

Step-by-step explanation:

To obtain the area of the shaded figure, first, you must calculate this as a rectangle, with the measurements: wide (4 units), and long (6 units):

How the figure isn't a rectangle, you must subtract the triangle on the top, so, now we calculate the area of that triangle with measurements: wide (4 units), and height (2 units):

In the end, you subtract the area of the triangle to the area of the rectangle, to obtain the area of the shaded figure:

I use the name "units" because the exercise doesn't say if they are feet, inches, or another, but you can replace this in case you need it.

Answer: 268

Step-by-step explanation:

From the question, we are informed that 67 out of 206 species of birds found in the Badlands nest there and that 824 species were found in the Badlands. The number of those that nest there would be:

= 67 × 824/206

= 67 × 4

= 268

Answer:

y = - 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, then

y = - 3x + c ← is the partial equation

To find c substitute (- 2, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = - 3x - 7 ← equation of line

Answer:

The equation would be y=-3x-7

Answer:

  0.5f -20.4

Step-by-step explanation:

There is only one term containing a variable (0.5f), but there are three constant terms. The constant terms can be combined by finding their sum in the usual way.

 -2.4 +0.5f -14 -4

  = 0.5f -(2.4 +14 +4)

  = 0.5f -20.4

[tex]\huge\boxed{\sf S = 8}[/tex]

Step-by-step explanation:

Opposite sides and angles of a ║gm are equal.

So,

6S - 8 = 3S + 16

6S - 3S = 16 + 8

3S = 24

Divide 3 to both sides

S = 24 / 3

S = 8

y2-y1/x2-x1. For A and B y2=4, y1=-4, x2=2 and x1=-2... Now u plug them in them, 4-(-4)/2-(-2)= 8/4=2. Slope equals 2. :)

Answer:

A

Step-by-step explanation:

we can conclude from the second equation that when

2x + y = 6 then y = 6 - 2x. so instead of y in the first equation we use 6 - 2x.

now the equation would look like this : 6 - 2x = x^2 - 4x + 3 .

then we bring everything to one side of the equation : x^2 - 2x - 3 .

now we'll have two results for x ( because x^2 - 2x - 3 = 0 has 2 answers )

one of them is -1 and other one is 3.

if we put them in the first equation we will have 8 and 0 for y.

so A is the answer

Answer:

The similarity postulate that applies is;

C. Similar - AA

Step-by-step explanation:

The given parameters are;

ΔABC with angles ∠BAC = 30°, ∠ABC = 100° and ∠BCA = 50°

ΔDEF with angles ∠EDF = 30°, ∠DEF = 100° and ∠DFE = 50°

Therefore, the interior angles of ΔABC are equal to the corresponding interior angles of ΔDEF, which satisfies the Angle-Angle (AA) condition for similarity of two triangles based on the congruency of two interior angles of one triangle to two interior angles of the other triangle.

Answer:

The zeros are (-5.5, 0) and (3.5, 0).

Step-by-step explanation:

g(t) = (t + 1)² − 20.25

0 = (t + 1)² − 20.25

20.25 = (t + 1)²

±4.5 = t + 1

t = -1 ± 4.5

t = -5.5 or 3.5

Answer:

The student multiplied by 5 instead of dividing by 5

Step-by-step explanation:

At the fourth step, the student multiplied each side by 5 rather than dividing it by 5. The opposite opperation from multiplication is division so they should have divided 5x and 60 by 5 here instead of multiplying it by 5. If this equation was done correctly, the correct answer would be x=12.

hello there!

it would be C

because

6/3=2 and 2*5=10 and 7*2=14

hope this helps

Answer:

aₙ = 75 x 0.2ⁿ⁻¹   or 75 x (1/5)ⁿ⁻¹

Step-by-step explanation:

a₁ = 75

a₂ = 75 x 0.2¹ = 75 x 0.2 ²⁻¹ = 15

a₃ = 75 x 0.2² = 75 x 0.2³⁻¹ = 3

.......

aₙ = 75 x 0.2ⁿ⁻¹   or 75 x (1/5)ⁿ⁻¹

Answer:

$24

Step-by-step explanation:

Let the total amount of her allowance = a

We are told that she spent $8 on belt

And the total amount she spent = $22

The Fraction of allowance spent on

Shirt = 1/4

Skirt = 1/3

Hence, the equation is given as:

1/4 × a + 1/3 × a + $8 = $22

Collect like terms

a/4 + a/3 = $22 - $8

a/4 + a/3 = $14

The Lowest Common Denominator = 12

3a + 4a/12 = $14

7a/12 = $14

Cross Multiply

7a = $14 × 12

7a = $168

a = $168/7

a = $24

Therefore, her total allowance = $24

Answer:

$80.625

Step-by-step explanation:

$75 for the iPod times 0.075 = 5.625 which is the sales tax.

Then $75 (Cost of iPod) + 5.625 (Sales Tax) = $80.625 (Price of the iPod including the sales tax)

Sorry, if I am wrong. I tried my best and Hope this helps ;)
