Answer:
a. 40
b. 0
c. 50
Step-by-step explanation:
a) 46 + (-2k) for k = 3 is ...
46 + (-2(3)) = 46 -6 = 40
__
b) 46 + (-2k) for k = 23 is ...
46 + (-2(23)) = 46 -46 = 0
__
c) 46 + (-2k) for k = -2 is ...
46 + (-2(-2)) = 46 +4 = 50
Answer:
Step-by-step explanation:
12z - 3 > 27z - 15
-15z - 3 > -15
-15z > -12
z < 12/15= 4/5
Answer:
A is a function; B, C and D are not.
Step-by-step explanation:
In other words: Identify the sole function among these relationships.
A function maps any input onto exactly one output.
If a relationship maps any input onto more than one output, it is not a function.
Thus, we eliminate B, C and D. In B, for example, we have the inputs {1, 2, 3}, where the '1' has two y-values associated with it.
On the other hand, A has the domain {-1, 0, 1, 2}, and all four inputs have exactly one associated output.
Answer:
6
Step-by-step explanation:
Let line WY be the line of reflection
RR has the midpoint at Z.
In other words, the line: =
SS is another line
It has a midpoint at X. In other words, line SX =
If SS = 12, then the line SX =
Because the shape is a parallelogram, it means that RZ = SX = 6
