There are 9 books stacked on a shelf. The thickness of each book is either 1 inch or 2 inches. The height of the stack of 9 book

s is 14 inches. Which system of equations can be used to determine x, the number of 1-inch-thick books in the stack, and y, the number of 2-inch-thick books?A. x + y = 9x + 2y = 14B. x + y = 142x + y = 9C. x + y = 14x + 2y = 9D. x + y = 92x + y = 14

Over [174]

Answer:

( C ) ΔMLN ≅ΔTSR

Step-by-step explanation:

Okay I got you!

So if the triangle <u>str</u> was flipped and rotated the other way then you will see that they are similar. They are asking what other "pairs" could you do to make it equivalent. Since M = T then you got your first pair. Next you go to N and when you look at the shape you'll see it will be S. N=S. And the last one would be L=R. I hope I was helpful enough! uwu Try to draw them out it will be helpful!!

1. What is the value of f(3) and what does it represent in the context of this example?
Marysya12 [62]

Answer/step-by-step explanation:

The graph of f(x) above is said to be the quantity of liquid a cylinder holds when poured into it at a given time, x.

This means the quantity of the liquid poured in the cylinder is a function of time.

f(x) values (quantity of liquid) are plotted on the y-axis, while x values (time) are plotted on the x-axis.

f(3) is the value at the y-axis when x = 3. Thus, when x = 3, y = 6.

Therefore, the value of f(3) = 6

f(3) = 6, represents the quantity of liquid poured in the cylinder at 3 seconds.
