Answer:
B. Deductive reasoning
Step-by-step explanation:
y is greater than or equal to negative 5 over 2 times x plus 5
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (5, −8) included in the solution area for the system? Justify your answer mathematically. (4 points)
Answer:
:Part A) The graph in the attached figure (see the explanation)
Part B) The ordered pair is not included in the solution area for the system (see the explanation)
Step-by-step explanation:
Part A) we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is (0,-8)
The x-intercept of the dashed line is (2,0)
----> inequality B
The solution of the inequality B is the shaded area above the solid line
The slope of the solid line is negative
The y-intercept of the solid line is (0,5)
The x-intercept of the solid line is (2,0)
The solution of the system of inequalities is the shaded area between the dashed line and the solid line
see the attached figure
Part B) is the point (5, -8) Included in the solution area for the system?
we know that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities
Substitute the value of x=5, y=-8 in each inequality and then analyze the results
Inequality A
----> is true
so
the ordered pair satisfy inequality A
Inequality B
---> is not true
so
the ordered pair not satisfy the inequality B
therefore
The ordered pair is not included in the solution area for the system
you will
have 14 rings
you will have 14 rings, because you have ten fingers, and ten plus 4 is 14.
hope it helps.
c) which yard has more room for my kids play in.
d) Which yard requires more fence to enclose?
Answer:
a) yard 1: 220yd^2 yard 2: 225yd^2
b) yard 1: 64yd. yard 2: 60yd
c) yard 2
d) yard 1
Step-by-step explanation:
area=base×height
perimeter=2×base+2×height
Answer:
a) 220 yd for the OLD HOUSE
a) 225 yd for the CURRENT HOUSE
b) 64 for the OLD HOUSE
b) 60 for the CURRENT HOUSE
c) the CURRENT HOUSE has more room for the kids (the area is bigger (area=space inside)
d) the OLD HOUSE requires more fence, because the perimeter is bigger (perimeter=the outside of the square)
Hope this helped!
