It should be -101. Just plug in 9 into x so it would be like f(9)= 9^2-20. Which equals -101
Answer 2

Answer:

  -101

Step-by-step explanation:

Put 9 where x is, and do the arithmetic.

  f(x) = -x² -20

  f(9) = -9² -20 = -81 -20

  f(9) = -101

9/9/108/126

Step-by-step explanation:

1/2bh is how you find the area of a triangle ! :)
This means that for both triangles, the area is 2 times the height, 9, then multiplied by one half. The area is 9 for both the left and right triangle.

The area of the rectangle is the product of the two lengths: 9 and 12, which is 108.

This means that the area of the entire trapezoid is 126.   :D

What is the equation of the line????????

Answers

Answer:

y=1/2x+2

Step-by-step explanation:

The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.

To find the gradient is a little more tricky, but we can follow the formula:

[tex]\frac{rise}{run}[/tex], where rise is the vertical value and run is the horizontal value

So we sub in our values:

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

And simplify:

[tex]\frac{1}{2}[/tex]

So now we sub in our new found values into y=mx+c:

y=1/2x+2

Answer: y = x/2 + 2 which is the 4th option from the top

Step-by-step explanation:

First find the slope which is (0-2)/(-4-0) = 2/4 = 1/2

So it's y = x/2 + c

Substituing (-4,0) into the equation we get

0 = -4/2 + c

0 = c-2

c = 2

So the equation is y = x/2 + 2 which is the 4th option from the top

what is the area of a triangle?

Answers

Answer: A=hbb2

Step-by-step explanation: For a triangle, we can find it by adding the lengths of its three sides. We can find the length of the fencing required for a triangular park by finding the perimeter of the triangle.

The area of a triangle is base x height divided by 2. A= bh/2.
If a triangle base is 10 and the height 5 so the area will be 10x5 = 50 /2 = 25. The area is 25.

Your total after 4 games of bowling was $28
and after 6 games it was $40. What was the
initial cost to rent the shoes before bowling
any games?

Answers

Answer:

$4

Step-by-step explanation:

Let x be the cost of a game of bowling and y be the cost to rent the shoes before the game then...

4x+y=28

6x+y=40

We can solve this system using elimination. In this scenario, we can eliminate y by subtracting the two equations...

-2x=-12

Divide both sides by -2

x=6

Plug 6 back in for x to solve for y

4(6)+y=28

24+y=28

Subtract 24 from both sides

y=4

It costs $4 to rent the shoes before bowling

Answer:

8)  14

10) 1

12) 81

Step-by-step explanation:

For number eight, you have to multiply out by 2. For example,

9 x 2= 18

2 x 2= 4

7 x 2= 14

For number ten, you have to subtract by 9. For example,

51 - 42= 9

10 - ___= 9

the space would be 1 because 10-1 equals 9

For number 12, you have to multiply out by 9

5 x 9=45

10 x 9= 90

9 x9= 81

If it is a Square pyramid, you’ll need to find the area of your base + the 4 triangular sides of the pyramid . If s=14 on one side, then you can find the base of your pyramid by doing 14^2. To find the triangles, you do (14 x 13)/2 x 4, or do (14 x 13) x 2. Once you find the area of all the surfaces, add them all together to get your total surface area.

An article was sold for ₹250 with a profit of 5%. What was its cost price?

Answers

Answer:

Selling Price 250

Profit =5%

We are given to find the cost price of articles .

First we find the profit

► Profit = 250/100 × 5

► Profit = 2.5×5

► Profit = 12.5

Cost Price = Selling Price - Profit

► Cost Price = 250-12.5

► Cost Price = 237.5

So, the cost price of the article is 237.5

Selling price of the article.

Profit percentage %.

To do:

We have to find the cost price.

Solution:

Let the cost price of the article be .

Profitpercent = SP-CP/CP × 100

5 = 250-x/x x 100

5x = (250-x) 100

x = (250-20) 20

x = 250 (20) - 20x

x + 20x = 5000

21x = 5000

x = 5000/21

x = 238

Therefore; cost price of the article is Rs 238
