Serjik [45]2 years ago

Step-by-step explanation:

=  \frac{ \frac{3}{x - 2} - 5 }{2 -  \frac{4}{x - 2} }

=  \frac{ \frac{3 - 5.(x - 2)}{x - 2} }{ \frac{2.(x - 2) - 4}{x - 2} }

=  \frac{ \frac{3 - 5.(x - 2)}{ \cancel{x - 2}} }{ \frac{2.(x - 2) - 4}{ \cancel{x - 2} }}

=  \frac{3 - 5.(x - 2)}{2.(x - 2) - 4}

=  \frac{3 - 5x + 10}{2x - 4 - 4}

=  \frac{ - 5x + 13}{2x - 8}

=  \frac{13 - 5x}{2x - 8}

The answer is D.

Mamont248 [21]

Answer:

\large\boxed{\left(r+\dfrac{1}{4}\right)\left(r-\dfrac{1}{4}\right)=r^2-\dfrac{1}{16}}

Step-by-step explanation:

\text{Use}\ (a+b)(a-b)=a^2-b^2\\\\\left(r+\dfrac{1}{4}\right)\left(r-\dfrac{1}{4}\right)=r^2-\left(\dfrac{1}{4}\right)^2=r^2-\dfrac{1^2}{4^2}=r^2-\dfrac{1}{16}

Could someone answer and explain these to me? That would be great, thanks!
Flura [38]

Answer:

y=-x^2

Step-by-step explanation:

given that y = x^2 is the function.

For equivalent to -y, we can multiply this equation both the sides by -1

We get -y = -x^2

Hence option G is right.

Also y =x^2 is a parabola with vertex at origin open up.

Hence if F is selected we get -y =(-x)^2 = x^2, this will make the parabola open down and hence this option is wrong.

H: -y=-x is wrong because this represents a line but we had original equation as that of a parabola

J) -y = x^(-2) means x^2y =-1

This implies that rate of change of y = 2/x^3 but rate of change of y has to equal 2x since y = x^2 is original. Hence only option G is right.

Answer:

- 25 and - 623

Step-by-step explanation:

Using the term to term rule with u₀ = - 3 , then

(a)

u₁ = u₀³ + 2 = (- 3)³ + 2 = - 27 + 2 = - 25

(b)

u₂ = u₁³ + 2 = (- 25)³ + 2 = - 625 + 2 = - 623
