Answer:

f^-1(x)= 9x+117

Step-by-step explanation:

hello :

let f(x) = y so : y = 1/9 x-13

calculate : x you have : 1/9x= y+13 so : x= 9(y+13)=9y+117

If f(x)=1/9x-13, then f^-1(x)= 9x+117

Solve 7x-4 = 5x+15 for x

tatiyna

$\bf{Hey\ there!}$

$\bf{7x-4 = 5x+15}$

$\bf{\underline{Subtract}\ 5x\ from\ \ on \ both\ of\ your\ sides!\downarrow}$

$\bf{7x-4-5x=5x+15-5x}$

$\bf{2x-4=15}$

$\bf{\underline{Add}\ by\ 4\ on\ each\ of\ your\ sides!\downarrow}$

$\bf{2x-4+4=15+4}$

$\bf{Cancel:-4+4\ because\ it\ equals\ 0}$

$\bf{Keep:15+4\ because\ it\ helps\ us\ solve\ for\ your\ answer}$

$\bf{15+4=19}$

$\bf{2x=19}$

$\bf{\underline{Divide}\ by\ 2\ on\ your\ sides!\downarrow}$

$\bf\frac{2x}{2}=\frac{19}{2}}$

$\bf{Cancel:\frac{2x}{2}\ because\ that\ gives\ you\ 1}$

$\bf{Keep:\frac{19}{2}\ because\ it\ gives\ you\ the\ the\ value\ of\ x}$

$\boxed{\boxed{\bf{Answer:x=\frac{19}{2}}}}\checkmark$

$\bf{Good\ luck\ on\ your\ assignment\ and\ enjoy\ your\ day!}$

What is the orthocenter of the triangle with two altitudes given by the lines x=-1 and y=x+1

timama [110]

The answer to the problem is as follows:

The orthocenter is where the altitudes of a triangle are concurrent (where they intersect each other). On your graph, that would be (-1,0)

I hope my answer has come to your help. God bless and have a nice day ahead!

31 ? 40 Find the measure of the indicated angle to the nearest whole degree.

Len [333]

Answer:

51°

Step-by-step explanation:

Reference angle (θ) = ?

Opposite side length = 31

Hypotenuse length = 40

Apply SOH, which is;

Sin θ = Opp/Hyp

Plug in the values

Sin θ = 31/40

θ = sin^{-1}(31/40)

θ = 51° (neatest whole degree)
