P-3=-4 solve the equation and check the solution

Mathematics

marishachu [46]3 years ago
7 0

To solve the equation, you need to isolate/get the variable "P" by itself in the equation:

P - 3 = -4      Add 3 on both sides to get "P" by itself

P - 3 + 3 = -4 + 3

P = -1

PROOF

P - 3 = -4      Plug in -1 for P

-1 - 3 = -4

-4 = -4

(-2,2)(2,-2)
slope = (-2 - 2) / (2 - (-2) = -4/4 = -1

as far as point slope form, there can be 2 answers...

y - y1 = m(x - x1)
slope(m) = -1
using points (-2,2)...x1 = -2 and y1 = 2
now we sub
y - 2 = -1(x - (-2) =
y - 2 = -1(x + 2) <== or could be written as y - 2 = - (x + 2)

y - y1 = m(x - x1)
slope(m) = -1
using points (2,-2)...x1 = 2 and y1 = -2
now we sub
y - (-2) = -1(x - 2) =
y + 2 = -1(x - 2) <== or can be written as y + 2 = - (x - 2)

either one of those answers is ur point slope form

A football team gained 9 yards on one play and then lost 22 Yards on the next. Write a sum of integers to find the overall chang
muminat
The football team gained 9 yards so that would be a positive number. Then they lost 22 yards so that would be a negative number. If you go to the left of the number line it would be a negative number. If you go to the right of the number line it would be a positive number. If you go to the left the numbers are getting smaller. If you go to the right the numbers are getting bigger. Hope this helps
