Answer:
6.4 oz are left.
Step-by-step explanation:
Start with the bottle being half full.
A bottle that is half full when it started with 16 oz is 1/2 16 oz = 8 oz
If he drinks 1/5 of the remaining amount, it means that he has 4/5 left.
4/5 * 8 = 32/5 = 6.4 oz or 6 oz and 2/5 of an ounce.
Answer:
Alternative A is the correct answer.
Step-by-step explanation:
For a function to have y-axis symmetry then it must be an even function such that; f(-x) = f(x). In alternative A, y = x^2 is an even function since; y(-x) = (-x)^2 = x^2 = y(x). The second function is also even since it has the absolute symbol. Finally, the cosine function is always an even function since cos(-x) = cos(x)
Answer: y = 3x+10
------------------------------------------------------------------------------------
Explanation:
The line y = 3x+11 is in slope intercept form y = mx+b where m = 3 is the slope. Anything parallel to this line will also have a slope of 3. Let's plug in m = 3 and (x,y) = (-2,4) which is the point this parallel line goes through.
y = mx+b
y = 3x+b ... replace m with 3
4 = 3(-2)+b ... replace x with -2; replace y with 4
4 = -6+b
4+6 = -6+b+6 ... add 6 to both sides
10 = b
b = 10
Since m = 3 and b = 10, this means that y = mx+b turns into y = 3x+10
