Answer:
Step-by-step explanation:
Given a function:
To find:
Function 
whose graph is a reflection in the y -axis for the given function = ?
Solution:
First of all, let us learn about the reflection of a point (
) in y axis.
For example, let us consider a point (3, 2) on the coordinate axis.
The reflection of this point in y axis will be (-3, 2)
OR
In other words, <em>To find the image of a point in y axis</em>:
the x coordinate is made of negative sign and y coordinate remains the same.
A line is nothing but a number of points joined together.
So, if we want to find reflection of a line or linear function in y axis, we just make the sign of x as negative.
Given that
We can write it as:
To find its reflection:
Please refer to the attached graphs of 
and 
.
So, the answer is:
So to compare boxes, you want to convert both to price per ounce unit.
So for smaller box, we have ratio $2.89 / 17 ounces which can be reduced to $0.17 per ounce. You just divide 2.89 by 17.
Now for larger box, we have ratio $3.29 / 24 ounces which can be reduced to approximately $0.14 per ounce. 0.137083333... to be exactly.
Larger box has smaller ratio compared to smaller box therefore larger box the is better buy.
The difference per ounce is 0.17 - 0.137083333... = 0.03291666... so that's 3.3 cents cheaper per ounce.
Final answer: <span>The larger box is the better buy because it is approximately 3.3 cents cheaper per ounce.</span>
Answer:
D
Step-by-step explanation:
intercept is -4 and slope is rise over run which is 3/1 = 3
put into slope intercept form to achieve answer D
Answer:
40% discount
Step-by-step explanation:
40% of 20 = 8
20 - 8 = 12
Answer: In my answer I got 9 because the formula to find the area it would be A=1/2b*h
Step-by-step explanation: How would you do this?
Well we know that the base equals 6 we have heighth so we would have to do 1.5*6 and that would give us 9 but if we round it would be 10 because 9 is closer to 10 than it is to 0.
thanks :)
