48 kg of 25% alloy should be used;
72 kg of 65% alloy should be used.

_____
I like to use a little X-diagram to work mixture problems. The numbers on the left are the contributions made by each constituent. The number in the middle of the X is the target value for the mix. The numbers in the center column are the differences along the diagonals. The numbers in the right column are in the same proportion but scaled to add to the total you need for this problem. (The scale factor is 3.)

Is the function even odd or neither
Andrei [34K]

Answer: Neither

The function is not even because it doesn't have y axis symmetry. In other words, reflecting it over the vertical y axis means it doesn't line up with itself. The left half is different from the right half.

The function isn't odd either. Why not? Because rotating it 180 degrees around the origin has the function curve looking completely different. A point like (3,6) will rotate to (-3,-6) which is not on the orange curve. This is just one counter-example as to why the function is not odd.

Reflection over the y-axis followed by a horizontal translation 1 unit left on the equation f(x)=x ​
aleksley [76]

Answer:

f(x) = -x -4 or f(x) = (-x)-4

Step-by-step explanation:

Let the graph of g be a translation of 4 units down followed by a reflection in the y-axis of the graph of f(x)=x. Write a rule for g.

Transformations can be found using this general formula: f(x) = a(bx-h)+k

For this question, we want a translation down as well as a reflection.

The two values we need to use are for k, a vertical translation, and b, a reflection over the y-axis.

Since we are translating down 4 units, k = -4

Since we are reflecting across the y-axis, b = -1

So, f(x)=(-x)-4

or

f(x)= -x -4
