-- these are called same side exterior angles, which means they are supplementary.
x + 9 + 2x + 6 = 180
3x + 15 = 180
3x = 165
x = 55
so, option B.
Answer:
1. A relation
2b. Continuous
Step-by-step explanation:
1: A relation is any set of ordered pairs. A function is a set of ordered pairs where there is only one value for every value.
2b: Continuous if the values belonging to the set can take on ANY value within a finite or infinite interval. A set of data is discrete if the values belonging to the set are distinct and separated.
Answer:
- (a) 104 = 4(12+x)
- (b) x = 14
Step-by-step explanation:
(a) The new side length of Ben's garden is (12+x), since x is the amount of increase above the existing 12 ft side length.
The perimeter is the sum of the lengths of the four equal sides, so is ...
perimeter = 4 × side length
104 = 4(12+x)
(b) We can solve this by dividing by 4, then subtracting 12.
26 = 12 +x . . . . . divide the above equation by 4
14 = x . . . . . . . . . subtract 12
The solution is x = 14.
Answer:
1/3x +4
is the inverse of f(x) = 3x + 4.
Check:
The purpose of the inverse property of multiplication is to get a product of one. So the inverse multiplied with the original number (or equation) should give us the product of one.
1 / (3x + 4) * 3x + 4 = 3x+4 / 3x+ 4 = 1
