How should i write this as an equation and how is the answer 1: 15 am?

Alright, so the equation we have here is 22.75x+32=128.69

Now we just solve

-32 on both sides, we get

22.75x=96.69

divide by 22.75 on both sides we get

x=4.2501989

So 4 hours

You add the 4.25 hours

10, 11, 12, 1 is the hour

And .25 is a fourth, and a fourth of 60 minutes is 15 minutes

So he left at 1:15 pm

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)
