98. Solve the equation 49 = x  50
x=1?
94. Determine if the following equation is a function: x=2
No?
92. Determine if the following equation is a function: y=5
No?
89. Solve for x in the equation:
6/7x  6 = 2
I got x=28/3
86. Does the following set of coordinates make a horizontal, vertical, or diagonal line when connected with a straight line? (2,2), (5,2)
a. horizontal
b. diagonal
c. vertical
d. none of the above
A
82. True or False: A function is a relation.
This is a little confusing...

92, yes, y=5 is a function.
82, a function is a relation, but not all relations are functions.
89 I cant tell what the problem is without grouping symbols.
All others right.

98. 49 = x  50
add 50 to both sides
x = 1
94. no (vertical line is not a function)
92. yes (horizontal line is a function)
89. (6/7)x  6 = 2
add 6 to both sides
= (6/7)x = 4
multiply both sides by (7/6)
= x = 28/6
86. a. horizontal
the y values are the same, so when they are connected, it makes a horizontal line
82. True, a function is a relation
81. f(2) = 2(2) + 1
= 4 + 1
= 3
78. f(2) = 3(2)  5
= 6  5
= 1
