A
The two equations are parallel. They have the same slope. You get two lines that never meet. The y intercept is -6 for the first one and + 6 for the second one.
B
Mutliply the second equation by 2
2(1/2y = -4x - 3)
y = -8x - 6
The two equations do not differ at all. There are an infinite number of solutions.
C
The slopes are different. One is plus 8 and the other is minus 8. These two equations will meet at exactly 1 point.
D
If you multiply the whole equation by - 1 you get the same thing as the first set of equations.
-1(-y = 8x +6)
y = -8x - 6
C<<<< Answer
Answer: Domain is (negative infinity,infinity)
Step-by-step explanation:
3x + 5 > 11
3x + (5 - 5) > 11 - 5
3x > 6
3x / 3 > 6 / 3
x > 2
x - 3 < 1
x (-3 + 3) < 1 + 3
x < 4
When subtracting / adding values to both sides, the inequality does not change.
When multiplying / dividing by a positive value, the inequality also doesn't change, but when multiplying , dividing with a negative value, the inequality must be flipped.
To find the x-intercept, substitute in 0 for y and solve for x.
Answer:14
Step-by-step explanation:0.35 times 14 equals 4.9
