CHOOSE ONE system of equations, A, B, or C to use for the following questions:

A) Linear Equation: y = -x + 1
Parabolic Equation: y = x2 + x - 2

B) Linear Equation: y = 2x + 1
Parabolic Equation: y = x2 - 5x + 7

C) Linear Equation: y = -2x + 2
Parabolic Equation: y = -x2 + 2x + 7

Show all work to solve your system of equations algebraically.

I chose B

Task 1: Part 2

Graph your system of equations and show the solution graphically to verify your solution.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

answer: you will have more water.

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
