How do u do problem 30? how I did
219/625

625

(5) 125

(5) 25

(5) (5)

219 • (5 to the 4th power)
(2 to the 4th power) • (5 to the 4th power)

219 • (5 to the 4th power) = 136,975

2 • 5 = (10 to the 4th power)

10 = 1000 = 0.136875

answer is 0.136875

is that right?
​

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

step-by-step explanation:

mean or average is 40.6

p - 6

step-by-step explanation

so you know that it cost $6 to see a movie you subtract p - 6 to get your answer

hope this !
