<span>4x-y = 15 3x+2y = -8 Multiplying the first equation by two makes for an easy elimination of the y variable. 8x - 2y = 30 3x + 2y = -8 Add vertically. 11x = 22. Divide by 11 on both sides and get x = 2. Plug into an equation. 4(2) - y = 15 8 - y = 15 8 = 15 + y 8 - 15 = y -7 = y. Thus the solution is indeed (2, -7).</span>

Anita needs 140 cubes to make a model. The figure shows the number of cubes in a box How many boxes of cubes does Anita need to
marishachu [46]

Answer:

3 boxes

Step-by-step explanation:

First, we find how many cubes are in each box, then we find how many boxes you need for 140 cubes.

<u>To find the number of cubes in a box we need to find the volume of the figure</u>

the top is 2 wide and 4 long so there are 8 cubes on each layer. Sense it is 8 cubes tall with 8 cubes on each layer the model has 8×8=64 cubes in each box.

<u>Now we divide then round up to find how many full boxes she needs to get 140 cubes or more.</u>

If 1 box has 64 cubes and she needs 140 cubes 140/64=2.187. Now we round up sense he can't buy a fraction of a box and the answer is: She needs 3 boxes

F(x) is just another term for Y. The variable of X is the value that you input into the f(x), which just stands for a function. Since the value that they asked for was 3, you know that they inputted the value of 3 as x. Just look where the coordinate at the point where the x-coordinate is 3 to find the answer.
