Answer:
Starting average customer rating was 5.
Step-by-step explanation:
Equation representing the average customer rating at Austin's bakery over time is,
y = 0.25x + 5
Here, 'x' represents the time or duration.
Starting average customer rating means value of y at x = 0.
Therefore, y = 0.25(0) + 5
y = 5
Starting average customer rating was 5.
Start off by "switching" the variables
![\bf 5\boxed{y}+4=(\boxed{x}+3)^2+\cfrac{1}{2}\qquad inverse\implies 5\boxed{x}+4=(\boxed{y}+3)^2+\cfrac{1}{2}](https://tex.z-dn.net/?f=%5Cbf%205%5Cboxed%7By%7D%2B4%3D%28%5Cboxed%7Bx%7D%2B3%29%5E2%2B%5Ccfrac%7B1%7D%7B2%7D%5Cqquad%20inverse%5Cimplies%205%5Cboxed%7Bx%7D%2B4%3D%28%5Cboxed%7By%7D%2B3%29%5E2%2B%5Ccfrac%7B1%7D%7B2%7D)
then solve for "y"
SINCE THEY ALL PAID EQUALLY, IT HAS TO BE A MULTIPLE OF 3. BY TRIAL AND ERROR, THE FIRST POSSIBLE MATCH IS 3.. SINCE 132 IS DIVISIBLE BY 11
Given:
<span>x^2 + y^2 + z^2 + 2x − 2y − 2z = 22
group the variables
x^2+2x + y^2-2y +z^2-2z = 22
then complete the squares
x^2+2x+1 </span>+ y^2-2y+1 + z^2-2z+1 = 22 +1 +1 +1
factor and simplify
(x+1)^2 + (y-1)^2 + (z-1)^2 = 5^2
Interpretation:
The centre of the sphere is at (-1,1,1) with a radius of 5
Answer:
2.67 miles (or 8/3 miles which is also 3 2/3 miles)
Step-by-step explanation:
S (shane) = 7
L (lissette) = ??
S = 3(L) - 1
7 = 3L - 1
8 = 3L
L = 2.67 miles
