Emanuel has 745 pictures in his phone. his memory is getting full, so he starts deleting 20 pictures every day. define each variable and write an algebraic expression to describe the number of pictures left on his phone after any given number of days. explain the answer,

So X = number of days

So 745-20x= how many pictures he has after any number of days

does that make sense?

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)

6.5

step-by-step explanation:

you said it was in the question
