The inverse of a relation switches the x- and y-values of the ordered pairs of the original relation true/false

True

Step-by-step explanation:

Example:

If f(x) includes:            (1,2)  (2,4)  (3,9)

Then, f⁻¹(x) includes:  (2,1)  (4,2)  (9,3)

Inverse of relations, when graphed, are flipped along the xy plane, or the line y=x. This is why the x and y coordinates are switched.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
