F(x)=4x^2-1 what is the inverse

TEA [102]

Let $y = F^{-1}(x)$ and $F(y) = x$

$4y^2 - 1 = x\\4y^2 = x + 1\\y^2 = \frac{x + 1}{4}\\y = \sqrt{\frac{x + 1}{4}}\\f^{-1} = \sqrt{\frac{x + 1}{4}}$

I need help with these questions

jolli1 [7]

Lol nice. to find the ribbon question we see that it says 5 meters. we divide this by 5. So x=$4/5
x= the cost of each meter. Simplify that and you will get $0.8 m\
now convert it to mm.
$0.8m x 1m/ 1000mm which equals 0.0008.

22.5(10-y)+27.5y=250

Nataliya [291]

Answer:

y = 5

Step-by-step explanation:

22.5(10-y)+27.5y=250

$225 - 22.5y + 27.5y = 250\\\\$

Combind like terms,

$225 + 5y = 250$

Subtract 225 from both equations to isolate the variable.

$5y = 25$

Divide both sides by 5 to isolate the variable and solve it.

$y = 5$
