Answer:
A. -10.21
Step-by-step explanation:
We know that he bought 3 sets of pencils for $30.63, so assuming each set costs the same amount, we divide 30.63 (the total cost) by 3 (the number of sets purchased) which would give us 10.21. Because we know that this money would have been subtracted from his bank account, then we know that it is a negative number.
Meaning the final answer would be -10.21
Answer:
x = -4 , 4
Step-by-step explanation:
The point (x,4) is equidistant from (0,1) and line y=-1
y=-1, it is horizontal line.
Let point on line be (x,-1)
Distance formula:
Distance between (x,4) and (x,-1) = Distance between (x,4) and (0,1)
hence, the value of x is 4 and -4
