Answer:
t+b<=122
Step-by-step explanation:
You know that the total is a maximum of 122, and it can be either tacos or burritos, so it is that.

Answer:
18.98 pounds
Step-by-step explanation:
Let 'e' represent the number of pounds of expensive candy Ellen should use. Then 27-e is the number of pounds of less expensive candy. Her total cost is ...
1.45(27 -e) +3.74e = 27(3.06)
(3.74 -1.45)e = 27(3.06 -1.45) . . . . subtract 1.45(27)
e = 27(3.06 -1.45)/(3.74 -1.45) = 27(1.61/2.29) ≈ 18.98
Ellen should use about 18.98 pounds of the expensive candy.

<em>Additional comment</em>
We showed the solution this way because it is the generic solution to any mix problem. The fraction of the mix that is the highest-value contributor is the ratio of the difference between the mix value and the lowest contributor to the difference between contributors. Here, that fraction is ...
(3.06 -1.45)/(3.74 -1.45) = (1.61/2.29)
Answer:
1.2192
Step-by-step explanation:
The point C at a coordinate of (-3, 4) is the center of dilation of shapes WXYZ to W'X'Y'Z'
<h3>How to determine the center of dilation?</h3>
The coordinates are given as:
- W = (-4, 3) X = (-2, 3) Y = (-4, 1) Z = (-2, 1)
- W' = (-6, 1) X' = (0, 1) Y' = (-6, -5) Z' = (0, -6)
- A = (-5, 4) B = (-3, 6) C = (-3, 4) D = (-1, 4)
Next, we plot the points on a coordinate plane
From the plane (see attachment), we can see that the point C at a coordinate of (-3, 4) is at the center of both shapes, and it is 1 unit from WXYZ and 3 units from W'X'Y'Z'.
Hence, the point C is the center of dilation

Answer:
y = -x/4 -2
Step-by-step explanation:
Linear function is in the form;
y = mx + b
The first point is (4,-3)
so we have;
-3 = 4x + b
The second point is (0,-2)
Thus;
-2 = 0(x) + b
b = -2
Put this in the equation above
-3 = 4x -2
-3 + 2 = 4x
4x = -1
x = -1/4
So the equation is;
y = -x/4 -2
