You have to do all this math to isolate the variable, so, first,
You have to use the opposite sign of negative 3, which is positive 3, and add on both sides!
Then, you isolate the variable by dividing -2 on both sides, which is...
-4!

Janine can use up to 150 one-inch blocks to build a solid, cube-shaped model. What are the dimensions of the possible models that she can build? How many blocks would Janine use for each model? Explain.
Answers
Answer:
A total of 12 dimensions to make perfect cubes. 1x1, 2x2, 3x3, 4x4, 5x5, 6x6, 7x7, 8x8, 9x9, 10x10, 11x11, 12x12. Can i get a brainliest?
Step-by-step explanation:
1x1=1
2x2=4
3x3=9
4x4=16
5x5=25
6x6=36
7x7=49
8x8=64
9x9=81
10x10=100
11x11=121
12x12=144
Janine can build 12 models of equal dimension (1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).
What is a cube?A three-dimensional object with six equal square faces is called a cube. The cube's six square faces all have the same dimensions.
A cube is become by joining six squares such that the angle between any two adjacent lines should be 90 degrees.
The surface area of the cube = 6 side².
The volume of the cube = side³.
Given that Janine can build up to 150 inches² area of cube.
Area of cube < 150
So,
13x13 = 169 > 150 And 12x12 = 144 < 150
So Janine can use up to 12 inches cube
Possible dimensions up to 12 inches are
(1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12).
Hence "Janine can build 12 models of equal dimension (1x1), (2x2), (3x3), (4x4), (5x5), (6x6), (7x7), (8x8), (9x9), (10x10), (11x11), (12x12)".

To determine if a graph is a function the "vertical line test is used. If any point on a graph has one x value go to two y values it is not a function.
Witht he four pictures, the two on the right use a horizontal line, so it doesn't tell at all, on the leftthe upper one is vertical but it doesn't show that one x value has two corresponding y values. So it must be the lower left one.
The lower left picture has a line at x=1, and it passes through the line of the graph at two different y values, 4 and -4. So this has two y values with one x value.
Answer:
I believe the graph with the line going through 1,0 (x,y) is correct because it doesnt pass the vertical line test
