Answer:
D.
Step-by-step explanation:
A function, by the easy-to-understand definition, is a relation where no x values are shared. The only set where each x value is different is in D. All the other sets share the same x value. Example: Set C has coordinates (-2, 1) and (-2, 2). The x coordinates are the same, so this isn't a function. It is only a relation.
D because the rest can be divided into cubes or rectangles.
Answer:
About 6 inches tall.
Step-by-step explanation:
One book has a thickness of 2
inches.
Another book has a thickness of 3.56 inches
Converting 2 inches to decimals will give; 2.4285714286 inches
If the books are stacked together, they become 2.4285714286 inches + 3.56 inches = 5.988571429 inches tall or about 6 inches tall (answer rounded up to nearest whole number).
2/5x - 1 = 9
+1 +1
10
