Answer: $12.45
Explanation: Two cartons cost $4.98, divide 4.98 by two to find the price of one carton of soda, 4.98 divided by 2 = $2.49. Multiply by 5 to find the cost of five cartons of soda. $2.49•5=$12.45
y = |x| is an absolute value function with vertex at (0, 0).
In a function, if you replace x with x - h, the graph shifts h units horizontally.
If you replace y with y - k, the graph shifts k units vertically.
Move the 7 to the left side.
y = |x - 4| - 7
y + 7 = |x - 4|
Now compare this function with the parent function y = |x|.
x has been replaced with x - 4. h = 4. The horizontal shift is 4 units to the right since 4 is positive.
y has been replaced with y + 7. We need to write y + 7 as y - k, so we write y - (-7). Then we see that k = -7. The vertical shift is 7 units down since 7 is negative.
Answer: the vertex is (4, -7), choice B.
I’m guessing either A or D. I’m it good at math either but I think I personally would go with A.
