Answer:
The correct answer is choice D.
Step-by-step explanation:
Since the parabola opens sideways, that means the function will feature 
and not 
, so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of is positive. Using all of this information, you'll find that the correct answer is D: 
.
This is never true. In a parallelogram, the diagonals will always bisect each other. Thus, each of these segments would always have to be equal.
Answer:
20x + 13
Step-by-step explanation:
5(4x + 3) - 2
5× 4x + 5×3 - 2
20x + 15 - 2
20x + 13
12w+15r=18.30 /*2
15w+10r=16.75 /*3
24w+30r=36.60, subtract this equation from the other one
45w+30r=50.25
21w=13.65
w=13.65/21
w=0.65 is a cost per pound for wheat flour
From the first equation we have
r=(18.30-12w)/15
r=(18.30-12*0.65)/15
r=0.70 is a cost per pound for rye flour
