Question 1 Pam decides to measure the time that it takes Ned's car to pass her. To make this measurement, she has to record two events. The first involves the front of Ned's car reaching her position and the second involves the back of Ned's car reaching her position. How far apart are the front and back of Ned's car as measured by Pam

answer: it's d

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2

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.
