Answer:
2*x-8
Step-by-step explanation:
the difference means subtraction and then "twice" means multiply by two
Answer:
Step-by-step explanation:
The function is f(x) = x²
<em>Transformation steps</em>
1. <u>Reflection across the x-axis:</u>
2. <u>Translation 3 units to the left:</u>
3. <u>Translation 4 units up:</u>
<u>The new function is:</u>
Correct choice is B
1600*0.85
The answer is 1360 tickets..
about the second one... well, is a "fait accompli" that using the pythagorean theorem, if x = 8 and y = 5, the hypotenuse must be √(8² + 5²) = √(89), which is neither of those choices.
5, 8, 13 are no dice, namely 5² + 8² ≠ 13
25, 64, 17 is are no dice too, because 25² + 17² ≠ 64²
however, 5,12 and 13 are indeed a pythagorean triple
also is 39, 80, 89.
when looking for a pythagorean triple, recall that c² = a² + b².
so the longest leg is the sum of the square of the small ones.
so what you'd do is, check the small legs, square them, add them up, if they're indeed a pythagorean triple, they "must" add up to the longest leg.
As x goed up one y goes down one so rate of change is -1
