Answer:y=16.8

Step-by-step explanation:

proportional means that x/y= constant

so there the constant is 1.75

if x=29.4 then 29.4/y =1.75

y = 29.4/1.75

We are asked to simplify the expression $\large\pmb{7x^2-x^2}$ .

$\triangle~\fbox{\bf{KEY:}}$

Combine like terms! :)

That's exactly what we need to do - combine like terms.

So, we subtract:

$\star~\large\pmb{7x^2-x^2}$

Which gives us:

$\star~\large\pmb{6x^2}$

Hope it helps you out! :D

Evaluate the function f(x) = sec(x - pi/2) for x = 0.

Anvisha [2.4K]

$\sec\left(0-\dfrac{\pi}{2}\right)=\sec\left(-\dfrac{\pi}{2}\right)=\dfrac{1}{\cos \left(-\dfrac{\pi}{2}\right)}=\dfrac{1}{0}$

So, the function $f(x)$ for $x=0$ is undefined.
