Write the inverse of f(x)=x2+4
Over [174]
F(x) = x² + 4
y = x² + 4

First, I reverse the equation to be
x² + 4 = y

Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)

Last, change into invers function
f⁻¹(x) = √(x - 4)

What is the length of DE
HACTEHA [7]

Answer:

DE = 20units

Step-by-step explanation:

In Δ ABC,

angle A is congruent to angle B.... (given)

therefore, ΔABC is an isoceles triangle.

therefore, CA = CB..... (side opposite to congruent angles are congruent in an isoceles triangle)

therefore, CB = 4 units

In ΔCDE,

angle D is congruent to angle E.... (given)

therefore, ΔCDE is an isoceles triangle.

therefore, CD = CE

therefore, CD = 8 units

ΔCDE ~ ΔCBA

therefore,

\frac{cd}{cb}  =  \frac{ce}{ca} =  \frac{de}{ab}   \\ therefore \:  \frac{8}{4}  =  \frac{8}{4}  =  \frac{de}{10 }  \\ therefore \\  \frac{2}{1 }  =  \frac{de}{10 }  \\ de \:  = 2 \times 10 = 20units

lisabon 2012 [21]

Answer:

x = 4

Step-by-step explanation:

The parallel segment divides the 2 sides of the triangle proportionally, that is

\frac{x}{8} = \frac{6}{12} ( cross- multiply )

12x = 48 ( divide both sides by 12 )

x = 4
