Answer:
if x ≥ 2, then y = x - 1
if x < 2, then y = -x + 3
Step-by-step explanation:
y = 1* |x - 2| + 1
y = |x-2| + 1
*** The rule on absolute value: |a| =a, if a ≥ 0; |a| = -a, if a < 0
If x-2 ≥ 0, then |x-2| = x-2, so y = (x - 2) + 1 = x - 1; y = x - 1
So if x ≥ 2, then y = x - 1
If x-2 < 0, then |x-2| = -(x-2) = -x + 2, so y = {-x + 2} + 1 = -x + 3; y = -x + 3
So if x < 2, then y = -x + 3
It would be mean.The mean is the average which is what she is looking for , since she wants a summerization of all the values in the data set.To find the mean (average) add all the numbers and then divide by the amount of numbers.
Answer:
1/10
Step-by-step explanation:
The answer is (a) 8m
This is because, if the length is 3 times as long as the width, you would multiply the numbers by 3 to give you a length.
8×3=24 16×3=48
We can stop at this point as we know the perimeter is 64 and to work out the perimeter you add up all the sides. 48+48+16+16 is larger than 64 so the only smaller number is 8. We can check this is correct by adding up the numbers.
8+8+24+24=64
We now know that the width of the field is 8m.
