Step-by-step explanation:
A function f(x) can be scaled by a factor of "a" and translated by (h,k) by the relation:
f(x) -> a f(x-h)+k
substitute f(x) by sqrt(x), then
sqrt(x) -> a*sqrt(x-h) + k
So the given equation is derived from f(x) = sqrt(x), hence a radical function.
When simplified, y=2(x+4)+5 equals y=2x+13

Answer:
Step-by-step explanation:
Let k represent Kim's age. Then Jack's age is k-5 and the total of their ages is ...
k + (k -5) = 21
2k = 26 . . . . . . . add 5, collect terms
k = 13 . . . . . . . . . divide by 2; Kim's age
k -5 = 8 . . . . . . . Jack's age
Kim is 13; Jack is 8.
The circumference of a circle is pi times D. So, 94.2/pi = 29.98 or about 30 in
Slope-intercept form is
, where m is the slope and b is the y-intercept.
Here, we first need to distribute the 1/3.
Next, we add 3 to both sides of the equation.
