You have a lot of questions here, I can help with some.

1) To find the inverse, switch the x and f(x) and solve for f(x).
x = 3f(x) - 7
x + 7 = 3(f(x)
(x + 7) / 3 = f(x)

2) It is a function, because each input pairs with only 1 output.

3) Any diagonal line would be a function.

4 - 8 (We can't do without the diagram)

9) f(-9) = 3(-9) - 6
f(-9) = -27 - 6
f(-9) = -33

10) f(-2) = 42 + 3
f(-2) = 45

What is the answer in that Equation

yulyashka [42]

$T=2\pi\sqrt{\dfrac{m}{k}}\ \ \ \ \ |divide\ both\ sides\ by\ 2\pi\\\\\sqrt{\dfrac{m}{k}}=\dfrac{T}{2\pi}\ \ \ \ \ \ |square\ both\ sides\\\\\dfrac{m}{k}=\dfrac{T^2}{4\pi^2}\ \ \ \ \ \ |multiply\ both\ sides\ by\ k\neq0\\\\\boxed{m=\dfrac{T^2k}{4\pi^2}}$

Select the letter of the best answer choice. Use 3.14 or 22/7 for π

valkas [14]

C = 2πr
141.3 = 2(3.14)r
141.3 = 6.28r
22.5 = r

What is the pattern (these are not ratios) 11 to 25, 27 to 41, 43 to 57, 59 to 73, __ __ __ __ __ __ __ __

Nuetrik [128]

Answer:

75, 89, 91, 105, 107, 121, 123, 137

Step-by-step explanation:

If you analyze how much each number is increased, you will notice it alternates between adding 2, then adding 14:

11 + 14 = 25.

25 + 2 = 27.

27 + 14 = 41.

41 + 2 = 43.

43 + 14 = 57.

57 + 2 = 59.

59 + 14 = 73.

That means you can simply, finish the pattern, alternating between adding 2 and 14. Then you will get these answers.

Drag each figure to show if it is similar to the figure shown or why it is not similar

natita [175]

Answer:

In the given shapes above, we can see that all shapes have four sides.

Above geometrical shapes could be named as Rectangles, parallelogram or quadrilateral.

First two shapes are Rectangles.

Third is a parallelogram.

Fourth and fifth shapes are Rectangles again.

Also we can say all those shapes with four side as quadrilaterals. (Note: A quadrilateral has four sides.)

Below shown shape has only three sides in it.

It is called a triangle when a shape has three sided close figure.

So, we could drag : Not similar - Different Type of shape.
