Answer:
If all possible vertical lines will only cross the relation in one place, then the relation is a function. This works because if a vertical line crosses a relation in more than one place it means that there must be two y values corresponding to one x value in that relation.
Step-by-step explanation:
Answer:
A. x = 4
B. RQ = 6
C. 48 square units
Step-by-step explanation:
A. 3x - 2 = 10
3x = 12
x = 12/3
B. a^2 + b^2 = c^2
8^2 + b^2 = 10^2
64 + b^2 = 100
b = sqrt (100 - 64
b = 6
C. Area of a triangle = (b*h)/2
b = (2)(6) = 12
Area = (12 * 8)/2 = 48 square units
Answer:
Divide her answer by -6 and see if her result is -108
Step-by-step explanation:
x ÷ -6 = -108
if not then the answer would be wrong
Answer:
(a) $6550
(b) $1511.54
Step-by-step explanation:
(a) You can solve the equation
... 12 × (monthly salary) = $78,600
by dividing both sides of the equation by 12.
... (monthly salary) = $78,600/12 = $6,550
(b) You know there are 52 weeks in a year, so you know that ...
... 52 × (weekly salary) = $78,600
... (weekly salary) = $78,600/52 ≈ $1,511.54 . . . . . . . divide by 52
