Answer:
Option F
Step-by-step explanation:
F). x + y = 3 -------(1)
x - 3y = -2 --------(2)
Equation (1) minus equation (2)
(x + y) - (x - 3y) = 3 - (-2)
4y = 5
y = 1.25
Hence, y is positive.
G). x + y = 3 --------(1)
x + y = -2 --------(2)
Both the equations represent parallel lines.
There are no solutions of the given equations.
H). x - 3y = -2 -------(1)
x + y = -2 -------(2)
Equation (2) minus equation (1)
(x + y) - (x - 3y) = -2 - (-2)
4y = 0
y = 0
Since, 0 is neither positive nor negative, y will be neither positive nor negative.
J). x + y = 3 -------(1)
x - y = 3 --------(2)
Equation (1) - Equation (2)
(x + y) - (x - y) = 3 - 3
2y = 0
Hence, y is neither negative nor positive.
Therefore, Option F is the answer.
Answer:
C = 12.57
Step-by-step explanation:
Circumference formula: C = 2πr
divide 4 by 2
4/2 = 2
plug it in
C = 2π(2)
C = 12.57
The mode of any data set is the number that appears most often.
In this case, no number appears more often than another.
In this data set, there is no mode.
Answer:
The answer would be 50
Step-by-step explanation:
.20 x 250 = 50
Answer:
y-8=5(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(-2-8)/(2-4)
m=-10/-2
m=10/2
m=5
y-8=5(x-4)
