MAVERICK [17]

Answer: f^-^1(x)=\frac{x+5}{11}

Step-by-step explanation:

To find the inverse, you replace the x with y, and y with x.

x=11y-5                       [add 5 on both sides]

x+5=11y                       [divide both sides by 11]

\frac{x+5}{11} =y

f^-^1(x)=\frac{x+5}{11}

What is the measure of x?
UkoKoshka [18]

Answer:

x=4

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x+5) *x = 6^2

x^2 +5x = 36

Subtract 36 from each side

x^2 +5x - 36 = 0

Factor

( x-4) (x+9) = 0

Using the zero product property

x-4 = 0  x+9 =0

x = 4  x=-9

Cannot be negative since that is negative length

x=4

How do I turn this equation into standard form?<br> 8x=-5y+3
NARA [144]

Answer:

Step-by-step explanation:

To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.

Ax+By=C

Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

8x−3=y

Move y to the left side of the equation because it contains a variable.

8x−3−y=0

Move 3 to the right side of the equation because it does not contain a variable.

8x−y=3
