PLEASE HELP?!?!?!

Answer:

c. In 2 seconds, the commuter train travels 120 feet.

Step-by-step explanation:

Given

The attached graph

Required

What does x-coordinate of 2 represents

Represent this coordinate with (x,y)

From the graph:

$x = 2$ when $y = 120$

Note that:

x = time and y = distance

So:

$(x,y) = (2,120)$

Which means:

At 2 seconds, the train has travelled a distance of 120ft

From the list of options, (c) is correct

Determine if the statement is true or false. If a linear system has the same number of equations and variables, then it must hav

lutik1710 [3]

Answer:

False

Step-by-step explanation:

Consider the equations with the same number of equations and variables as shown below,

Case 1

$x_{1} + x_{2} = 0\\x_{1} + x_{2} = 1$

This equation has no solution because it is not possible to have two numbers that give a sum of 0 and 1 simultaneously.

Case 2

$x_{1} + x_{2} = 1\\2x_{1} + 2x_{2} = 2$

This equation has infinitely many possible solutions.

Therefore it is FALSE to say a linear system with the same number of equations and variables, must have a unique solution.
