Answer:
Check the images below.
Step-by-step explanation:
A Piecewise Function is just a merge of several functions in a single graph. Each function takes a part of the x axis of the graph. On the images below I made the sketches of the graphs identifying them with colors. Note that you have to identify whether the function includes the value or not at the end of their line, if they include them, the circle at the end of the line will have a fill color, it willbe a closed circle. If they do not include the values, they have open circles.
Y= mx+b
(16, -7) = (x,y)
2(16) - 3y = 12
32 - 3y = 12
32 - 12 = 3y
20/3 = y
6.6 = y
2x-3(-7) = 12
2x+21 = 12
2x = 12 - 21
x = -9/2
Insert the values into y = mx + b
solve for m and then solve for b
Answer:
334 in^2.
Step-by-step explanation:
The surface area = area of the top prism + area of the bottom - 2 * area of the base of the top smaller prism
= 2(5*3 + 5*3 + 3*3) + 2(9*7 + 9*5 + 7*5) - 2* 3*5
= 2* 39 + 2*143 - 30
= 334
Answer:
A
Step-by-step explanation:
the rest of the tables have two of the same numbers and it is not a function if it does that.
