Which function is not a translation of f(x)=x2+17? f(x)=−x2−17 f(x)=(x−4)2 f(x)=(x+12)2 f(x)=(x−4)2+17
ruslelena [56]
F(x) = -x²-17 is not a translation.

A translation of this graph would either have something added to/subtracted from the end of the function (the c value) or something added or subtracted to x before it is squared.  f(x) = -x²-17 is a reflection, as the coefficient of x² is negative.

Every other choice has something either added to or subtracted from either x before it is squared or from the end.

An angle measures 6° more than the measure of its complementary angle. What is the measure of each angle?
Tresset [83]

Answer:

42 degrees, and 48 degrees

Step-by-step explanation:

set up an equation to find x, the first angle measure

(x+6)+x=90

then simplify:

2x+6=90

2x=84

x=42

So, the first angle measure is 42, now to find the second angle measure, add 6 to 42, and you will get 48.
