12 would be your answer
-2*-1= 2
2*6=12
so 12

Use the base example of two people walking to describe a system of two linear equation has i.) 0 solution 2) 1 solution 3) an in

sveta [45]

The system has:

No solutions for two parallel lines.
1 solution for two nonparallel lines.
Infinite solutions for two equations that describe the same line.

<h3>How to identify the number of solutions for the systems?</h3>

A system of two linear equations is given by:

y = a*x + b

y = c*x + d

1) The system has no solutions when both lines are parallel lines, this happens when both lines have the same slope and different y-intercept.

y = a*x + b

y = a*x + d

2) The system has one solution when the lines have different slopes:

y = a*x + b

y = c*x + d

3) The system has infinite solutions when both equations describe the same line:

y = a*x + b

What are the zeros of P(m) = (m2 – 4)(m2 + 1)?

devlian [24]

Answer:

m=4, -1

Step-by-step explanation:

if i am interpreting this correctly, you are wanting to find at what value of m would the solution be zero.

so, there are two expressions that can cause an answer of 0.

1) if 0=m2-4

so solve for m2, and you get 4=m2

2) if 0=m2+1

solve for m2, and you get -1=m2

you can check your work by plugging the values back into the equation.

P(m)=(4-4)(4+1)

=(0)(5)

=0

and

P(m)=(-1-4)(-1+1)

=(5)(0)

=0
