Write an expression for the perimeter of the triangle shown below:

A). 4.5x + 29

B). 4.1x − 29

C). 4.5x − 29

D). 4.1x + 29

Answer:

Step-by-step explanation:

f(x) = 2/3 x + 3

x = 9

f(9) = 2/3 * 9 + 3            Divide 9 by 3

f(9) = 2 * 3 + 3               Combine 2 * 3

f(9) = 6 + 3                    Combine

f(9) = 9                          The answer is just a coincidence. The answer for the next one shouldn't be - 3

f(-3) = 2/3 *(-3) + 3         Divide 3 into - 3

f(-3) = 2*(-1) + 3

f(-3) = -2 + 3

f(-3) = 1

How was this done?

You should observe that whatever value you see on the left in the brackets, appears where the x is on the right. This is a very important concept. You should do your best to understand it because algebra is sort of based on it.

Answer:

-19

Step-by-step explanation:

Previous position in sea + change in position= current position

-26+7= -19

Hope this helps! :)

Answer:

It is -19

Step-by-step explanation:

Well, you would do this -26 + 7 because the diver dove 26 feet BELOW sea level, which is also -26. He then ascends 7 feet, which means he is coming UP. So -26 + 7 = -19.

Answer:

The correct answer would be: "Maximum height 9 feet; horizontal distance 9 feet".

Step-by-step explanation:

I know this not only because I already took the test, BUT by graphing the equation (you can use graphing apps) it'll give you the answer.

Her maximum height is 9 feet & she is horizontally 9 feet from the end of the ramp when she lands.

The path of the skateboarder can be modelled by the equation,

(x-3)² = -4(y-9)

Now, from the equation, solving y,

(x-3)² = -4(y-9)

⇒ y-9 = -[tex]\frac{1}{4}[/tex](x-3)²

⇒ y = -[tex]\frac{1}{4}[/tex](x-3)² + 9

∴ Maximum height is 9 feet.

We have to take y = 0,

Now, -[tex]\frac{1}{4}[/tex](x-3)² + 9 = 0

        ⇒ -(x²-6x+9)+36 = 0

        ⇒ -x²+6x-9+36 = 0

        ⇒  x²-6x-27 = 0

        ⇒ x²-9x+3x-27 = 0

        ⇒ (x-9)(x+3) = 0

        ⇒ x = 9 or x = -3

Neglecting the negative value we get, x = 9

So, Her horizontal distance from end of the ramp is 9 feet.

Answer:

Infinitely many solutions

Step-by-step explanation:

6x+18=2(3x+9)

6x+18=6x+18

Since both sides are equal to each other, then there are infinitely many solutions because no matter what x is, both sides will be equal to each other.

Answer:

infinite many solutions, (C)

Step-by-step explanation:

Once you distribute you get 6x+18 on both sides. Meaning that the answer is this has infinite many solutions.

Answer:

Step-by-step explanation:

According to the first part of the equation, hourly pay is $25, up to 38 hours.

Overtime is paid over 38 hours.

Find the hourly pay for overtime, taking x = 39 and finding the difference with the total at x = 39 and x = 38, then we have the payment for one hour.

Correct choice is C

Answer:

19.5

Step-by-step explanation:

side is 6.5 bigger, so minus the 6.5 from the total perimeter of 65 and divide by 3.

65- 6.5 = 58.5

58.5 ÷ 3 = 19.5

equal sides are 19.5

longer side is 19.5 + 6.5

Answer:

19.5 inches

Step-by-step explanation:

You can interpret this problem as x + x + (x + 6.5)=65, with x being the length of the equal sides.

Simplified, this equation becomes 3x+6.5=65.

Solving, this becomes 3x+6.5-6.5=65-6.5 which comes out as 3x=58.5. Next, we divide this equation by 3 on both sides, which then comes out to x=19.5. Therefore, the length of equal sides are 19.5.

Check: There are two equal sides, so 19.5+19.5. Since the base is 6.5 inches bigger than either of the equal sides, the base is equal to 19.5+6.5=26. Adding these values all together comes out to 19.5+19.5+26=65.

Answer:

A   = 981.3 ft^2

Step-by-step explanation:

Here we're calculating the area of a semicircle of radius 25 ft.

The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.

Here pi = 3.14 and r = 25 ft, and so the area/space in question is

A = (1/2)(3.14)(25)^2

A   = 981.3 ft^2

The space does Snoopy have to roam is 490.625 square feet.

Given that, Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn.

The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.

The formula for the area of the sector of a circle is /360° (r²) where r is the radius of the circle and is the angle of the sector.

From the attached image, we see that snoopy is at the edge of a circle with the garage taking up a quarter of that circle.

Now, the area of space Snoopy was roaming

= 90°/360° × (3.14 × 25²)

= 1/4 × (3.14 × 625)

= 0.25 × 1,962.5

= 490.625 square feet

Therefore, the space does Snoopy have to roam is 490.625 square feet.

Answer:

  x = (y +2)/3

Step-by-step explanation:

The flowchart is trying to help you see that you "undo" what is done to x, in reverse order.

  x is first multiplied by 3, then -2 is added.

First, we want to undo the addition of -2, so we add the opposite of that to y:

  y = 3x -2   ⇒   y +2 = 3x

Then we want to undo the multiplication by 3, so we divide by 3:

 y +2 = 3x   ⇒   (y +2)/3 = x

The solution for x is ...

  x = (y +2)/3

Additional comment

In your diagram, each box has the inverse operation of the one in the box above it. The inverse of subtracting 2 is adding 2. The inverse of multiplying by 3 is dividing by 3. The arrows connecting the boxes are intended to show you that these inverse operations occur in the reverse order of the original operations, as we described above.
