Answer:
y=-4 is a function
Step-by-step explanation:
It passes the vertical line test, and each x has only one y, so it is a function.
x = -4 is NOT a function because one x has multiple y values. It does not pass the vertical line test.
Answer:
$1.54
Step-by-step explanation:
18% of $15.85 is 2.853, so your total is $18.703
20% of $14.30 is 2.86, so their total is $17.16
So the difference is $1.543, rounded (since your dealing with money) would be $1.54
Substitute in the values and solve.
1) B
For A:
3 = 4(1)
<u>This is NOT true.</u>
For B:
-4 = 4(-1)
<u>This IS true.</u>
For C:
-1 = 4(-4)
<u>This is NOT true.</u>
For D:
-4 = 4(1)
<u>This is NOT true.</u>
2) None. Possible solutions: (0,2) (1,-5)
For A:
2 = -7(1) + 2
2 = -7 + 2
<u>This is NOT true.</u>
For B:
-52 = -7(8) + 2
-52 = -56 + 2
<u>This is NOT true.</u>
For C:
-35 = -7(5) + 2
-35 = -35 + 2
<u>This is NOT true.</u>
For D:
-7 = -7(1) + 2
-7 = -7 + 2
<u>This is NOT true.</u>
