Answer:
2
Step-by-step explanation:
2(3j + 4 + 9j) = 56
24j + 8 = 56
2(12j + 4) = 56
1 whole cake= 1/4 + 1/4 + 1/4 + 1/4
1/4= 0.25
So we multiply 10 4/5oz per 1/4 cake by four to find out how many ounces are needed for 1 whole cake.
T= total ounces for 1 whole cake
T= (1 ÷ cake portion)(# ounces)
T= (1/0.25)(10 4/5)
change mixed fraction to improper
T= (4)(54/5)
multiply 4 by the numerator
T= (4*54)/5
T= 216/5 ounces for whole cake
T= 43 1/5 ounces for whole cake
Hope this helps! :)
The definition of the piece-wise function is:

<h3>What is a piece-wise function?</h3>
A piece-wise function is a function that has different definitions, depending on the input.
In this problem, for inputs between -2 and 2, the function is a line that goes through (-2,-4) and (2,6). The slope is:
m = (6 - (-4))/(2 - (-2)) = 2.5.
The y-intercept is of b = 1, hence the rule is:

For x greater than 2 and less than 6, the function is constant at -3, hence the rule is:
.
