1) Since an increase of 25% represents an increase of 1/4 of the whole.
2) And we have 4/5, increasing 1/4 we'll write:

3) So representing in the diagram an increase of 25% would be:
x =4/5
x(1.25) =y
4/5(1.25) =1
b. -3/4 because the line of the slope is negative
Laurie must make 4.5 batches for the school bake sale, and 2 batches for her family. Therefore, in total, Laurie must make 4.5 + 2 = 6.5 batches of cookies.
Since each batch of cookies requires 0.25 pounds of butter, we can multiply that amount by the number of batches baked: 0.25 * 6.5 = 1.625 pounds of butter.
So Laurie uses 1.625 pounds of butter to make all the cookies.

Answer:
Step-by-step explanation:
hello :
the system is : y= 3x+4....(*)
y+6=3x....(**)
by (**) : y = 3x - 6
so : y= 3x+4
y= 3x - 6
means : 3x+4 = 3x - 6
4= -6.......(false)
conclusion : no reals solutions
