Answer:

$(x+3)^{2} +(y+5)^{2} =16$

Step-by-step explanation:

the general equation of a circle is

$(x-h)^{2} + (y-k)^{2} =r^{2}$

with (h,k) being the centre of the circle and r the radius

Answer:

C) The parabola is narrower and reflected across the x-axis.

Step-by-step explanation:

The original parabola has equation:

$f(x) = {x}^{2}$

The transformed parabola has equation

$f(x) = - 1.4 {x}^{2}$

How wide the graph is can be determined by the absolute value of the coefficient.

The smaller the absolute value of the coefficient, the wider the graph.

Since

$|1| \: < \: | - 1.4|$

The original graph is wider than the transformed graph.

Also the negative factor tells us there is a reflection in the x-axis.

Need help! With this question! Thank you

Answer:

M = 42

Step-by-step explanation:

Ooo..I'm actually good at these!!

So its simple...All you do is take the equation and divide both sides by 4.5

When we divide, we get m alone.

4.5m = 189

/4.5 /4.5

m = 42

Hope this helps!! Can I have brainliest please?!?

Find the inverse of the function f(x)=5x-6/x+2

Naily [24]

Answer:

$f^{-1}(x)=\dfrac{2x+6}{5-x}$

Step-by-step explanation:

Swap x and y, then solve for y.

$x=\dfrac{5y-6}{y+2}\\\\x(y+2)=5y-6\\\\xy+2x=5y-6\\\\2x+6=5y-xy\\\\y=\dfrac{2x+6}{5-x}\\\\f^{-1}(x)=\dfrac{2x+6}{5-x}$
