Answer:

Step-by-step explanation:

-x^2 + 3xy^2

Now replacing X and y with their values

-(-4)^2 + 3 * -4 * -1^2

4^2 - 12

Two cyclists , A and B , are going on a bike ride and are meeting at an orchard . They left home at the same time . Functions A

vova2212 [387]

Answer:

Cyclist A lives farther from the Orchard

Step-by-step explanation:

Given

$A(x) =48.5 -21x$

$B(x) =42 -16.8x$

Required:

Who lives farther from the Orchard.

To do this, we simply calculate the y intercept.

This represents the total distance traveled to get to the Orchard

To calculate y intercept, we set $x = 0$

So:

$A(x) =48.5 -21x$

$A(0) = 48.5-21*0 =48.5-0 =48.5$

$B(x) =42 -16.8x$

$B(0) = 42 - 16.8*0 =42-0 =42$

From the above computation:

$A(0) > B(0) \to 48.5 > 42$

Hence;

Cyclist A lives farther from the Orchard

Consider the function attached below

Masja [62]

Answer:

Step-by-step explanation:

Hello,

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

now let's replace x by 7 it comes

$f^{-1}(7)=\dfrac{(7-5)^2}{2}=\dfrac{2^2}{2}=2$

hope this helps
