Answer:
Answer is B
Step-by-step explanation:
If point D with coordinates (a,b) is reflected over the line y=x then the image point D' coordinates are (b,a) (see picture for details).
The middlepoint M of segment DD' lhas coordinates and lies on the line y=x (since its coordinates are equal), DD' is perpendicular to the line y=x and DM=D'M. All these remarks show that the point D' is the image point of D.

Step-by-step explanation:
Answer:
30 pounds of raspberries and 50 pounds of blueberries
Step-by-step explanation:
Let's use b to represent blueberries and r for raspberries. Each pound of raspberries costs $1, so to find the total cost of raspberries we use 1r, which is just r. For blueberries, we do 3.25b.
r+3.25b=192.5
We also know that we can combine the numbers for 80 total pounds.
r+b=80
We can subtract the two equations we have made to eliminate the r and solve for b.
2.25b=112.5
We divide both sides by 2.25.
b=50
We know that r+b=80, so if b is 50 then r must be 30.
Have a wonderful day! :D
