Find the inverse of y=1/2x+6

Komok [63]

Answer:

$y = 2x - 12$

Step-by-step explanation:

We want to find the inverse of

$y = \frac{1}{2}x + 6$

We interchange x and y.

$x = \frac{1}{2}y + 6$

We need to solve for y, so let us multiply through by 2.

$2x = y + 12$

Subtract 6 from both sides.

$y = 2x - 12$

Therefore the required inverse is

$y = 2x - 12$

If you have a semi-circle with a diameter of 8.6ft, what's the semi-circles area?

galben [10]

So,

The diameter is 8.6ft. We need to convert to radius.

2 radius = 1 diameter

8.6/2 = 4.3 ft.

$\pi r{2}$

$\pi 4.3^{2}$

$\pi 18.49$

3.14(18.49)

58.0586ft.²

Divide by 2 (semi-circle)
29.0293ft.²

Pls help find x in both

RUDIKE [14]

Answer:

Step-by-step explanation:

In similar triangles, corresponding sides are in same ratio

$\frac{28}{24} = \frac{3x-9}{x +8}\\\\\frac{7}{6}=\frac{3x-9}{x+8}\\$

Cross multiply,

7*(x + 8) = 6*(3x -9 )

7x + 7*8 = 6*3x - 6*9

7x + 56 = 18x - 54

56 = 18x - 7x -54

56 = 11x - 54

11x - 54 = 56

11x = 56 +54

11x = 110

x = 110 /11

x = 10

PR = 3x -9

= 30 - 9

PR = 21
