|x - 1| > 4 ⇔ x - 1 > 4 or x - 1 < -4 |add 1 to both sides
x > 5 or x < -3
Answer: c. {x| x < -3 or x > 5}.
Answer:
x = 2
Step-by-step explanation:
Used a scientific calculator.
Answer:
[-8,8]
Step-by-step explanation:
domain is the set of x values that the graph covers
This graph starts at -8 and ends at 8 (including those points and all points between them).
That makes the domain [-8,8]
Answer:
140
Step-by-step explanation:
Solve 40% of 350.
Answer:
Step-by-step explanation:
Slope of a line passing through two points
and
is given by the formula,
Slope = 
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '
' =
= 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '
' =
= ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.
