Task 1: Part 1
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 solutions for my system:
(this should be 2 ordered pairs)

d

step-by-step explanation:

d

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
