Answer:
Lizzy's recipe is not a proportional relationship with the brownie recipe because of the difference in ratio.
Step-by-step explanation:
Brownie recipe:
Cocoa powder = 3 parts
Flour = 2 parts
Ratio of cocoa powder to flour = 3 : 2
Lizzy's recipe:
Cocoa powder = 1 cup
Flour = 1 cup
Ratio of cocoa powder to flour = 1 : 1
8.25*40= $330 a week
330*12= $3960 a year
Answer:
The width is 19 units. The length is 21 units.
Step-by-step explanation:
W=width: L=length=W+2; P=perimeter=80
P=2(L+W)
80=2(W+2+W)
40=2W+2
38=2W
19=W answer 1: The width is 19 units.
L=W+2=21 ANSWER 2: The length is 21 units.
CHECK:
P=2(L+W)
80=2(21+19)
80=2(40)
80=80

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
x² + x + 1 ← to obtain vertex form use metod of completing the square
To complete the square
add/ subtract (half the coefficient of the x- term )² to x² + x
x² + 2(
)x + 
- + 1
f(x) = (x + )² + 
← in vertex form
