Please help me, solve for y 2x-y=5

1 answer:

3 0

2x−y=5

Add -2x to both sides.

2x−y+−2x=5+−2x

−y=−2x+5

Divide both sides by -1.

$\frac{-y}{-1} = \frac{-2x+5}{-1}$
‌y=2x−5

Answer:

y=2x−5

If <ABC measures 100 and is inscribed in a circle O. find <BAO and <BCO

satela [25.4K]

Answer:

<BCO = <BAO = 20degrees

Step-by-step explanation:

If <ABC measures 100 and is inscribed in a circle O. find <BAO and <BCO

To get <BAO and <BCO, we need to get <AOC first.

From the figure, it can be seen that triangle ABC is an isosceles trinagle. Hence;

<BAC + <BCA + 100 = 180

Since <BAC = <BCA

<BAC + <BAC = 180 - 100

2<BAC = 80

<BAC = 80/2

<BAC = 40

Also;

<BAO = <BCO and <BAO = <BAC/2

<BAO = 40/2 = <BCO

Hence <BCO = <BAO = 20degrees

Find the inverse function. f (x)=1/2x+6

Lana71 [14]

The inverse of this function is f(x) = 2x - 12.

You can find the inverse of any function by switching the f(x) and x values in the equation. Then you can solve for the new f(x) value. The result is your inverse function. The work for this one is below.

f(x) = 1/2x + 6 ----> switch f(x) and x

x = 1/2f(x) + 6 ----> subtract 6

x - 6 = 1/2f(x) ----> multiply by 2

2x - 12 = f(x) ----> change the order for consistency.

f(x) = 2x - 12
