If x is positive and x^2 = 729, what is the value of x? Please help

X= 27

Step-by-step explanation:

Square root both sides

x = + or - 27

but since it’s positive x=27

a² + b²= c²

24² + 7² = c²

c= 25

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
