Answer:
C {(-4, 2), (-2, 1), (2, 0), (4, 5)}
Step-by-step explanation:
The domain is the set of x-values for which the function is defined.
<h3>Choices</h3>
A) The relation is <em>only defined for x=2</em>. It is not a function, because x=2 maps to an infinite number of y-values.
B) The domain is an infinite number of x-values. The listed values are included in the domain, but they are <em>not the entire domain</em>.
C) The list of first-values in the ordered pairs is the domain of the function it matches the given domain.
D) The list of first-values in the ordered pairs is <em>not the same as the given domain</em>.
So we can get from these two equations that y = 6x + 2 = 6x + 9
6x + 2 = 6x + 9
0 = 7 , but that's incorrect, so this set has no solution.
Answer:
Y = 90
X = 52
Step-by-step explanation:
Y is on a straight line. The sum of the angles on a straight line is 180.
The only other angle (that is marked) on this straight line, is a 90 degree one. So, <y + 90 = 180.
<y = 90.
Now <x + 38 = 90
so, x = 52
