Mrs. Ching has 33 students in her fourth-grade class. Her students are making collages on Friday, so she brings in 5 magazines for each student. How many magazines does Mrs. Chung bring to class. What equation correctly solves the word problem

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

the furthest the dog can be is 508 meters away from the house, and the closest he can be is 492 meters away from the house.

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
