Find the inverse of y=100-x^2

Mathematics
1 answer:
AnnyKZ [126]2 years ago
5 0

Answer:

The inverse  is ±sqrt(100-x)

Step-by-step explanation:

To find the inverse, exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x - 100 = -y^2

Divide by -1

-x +100 = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) =y

The inverse  is ±sqrt(100-x)

I need help on this it is a fraction subtract another fraction which is negative thx to whoever helps 5/7-(-1/7)
Sav [38]

Answer:

\frac{5}{7}-(-\frac{1}{7})=\frac{6}{7}

Step-by-step explanation:

To evaluate :

\frac{5}{7}-(-\frac{1}{7})

Solution:

Two negatives multiply to become a positive.

Thus, we can remove parenthesis by reversing the signs of the fraction by multiplying the negative outside.

⇒ \frac{5}{7}+\frac{1}{7}

Since the denominators are same for both fractions, so we simply add the numerators.

⇒ \frac{5+1}{7}

⇒ \frac{6}{7}  (Answer)

On the map below, all numbered streets run parallel to each other. Both 3rd and 4th streets are intersected by King Avenue.
frosja888 [35]

X=105°

Y=105°

Z=105°

let the angle below 75° which is the 4th Street be A

75°+A=180°[being adjacent angle]

A=105°

X=A[Verticall opposite angle]

Z=A[Corresponding angle]

Y=X[alternate angle]
