For inverse functions, switch the position of x and y, and solve for y.
y= x^2-16
x= y^2-16
x-16 = y^2
Answer:
see attached
Step-by-step explanation:
GeoGebra conveniently computes the point coordinates of the reflected points. In the attached, the reflections are done in the order listed in the table, so A' is reflected across x; A'₁ is reflected across y; A'₂ is reflected across y=x, and A'₃ is reflected across y=-x. The same notation is used for the other points. The values are listed in order, so you can copy them down the column in your table.
Answer:
median= 6.5
Step-by-step explanation:
6= 2+5+x+1+x+2+7+9/6
summing up the values
26+2x=36
collecting like terms,
2x=10
divide both sides by 2
x= 5
5+1=6
5+2=7
so the numbers are 2 5 6 7 7 and 9
the median = 6+7/2
= 6.5
You will have to use trig to solve this:
The side you have is adjacent to the known angle
The side you are looking for is opposite the known angle
^^^This means you need to use tan:
tan(24) =
.445222 =
^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x
5.3 ≈ x
Hope this helped!

Step-by-step explanation:
32=x+x+4+2x(x=able x+4=sister 2x=brother)
32=4x+4
28=4x
x=7
7+4=11
