12x+4y=1 6x-2y=3 substitution, elimination, or graphing ?

Mathematics
1 answer:
goldfiish [28.3K]3 years ago
8 0

Answer:

y = -5/8

x = 7/24

Step-by-step explanation:

elimination

12x + 4y = 1 | ×1 |

6x - 2y = 3 | ×2 |

12x + 4y = 1

12x - 4y = 6

_________--

8y = -5

y = -5/8

elimination

12x + 4y = 1 | ×1 |

6x - 2y = 3 | ×2 |

12x + 4y = 1

12x - 4y = 6

_________+

24x = 7

x = 7/24

G = {(5,3), (2, 3), (6,4)} Is G^-1 a function and why?
sleet_krkn [62]

Answer:

The inverse relation G^(-1) is not a function. Why not? Because the y value y = 3 is paired up with more than one x value (x = 5, x = 2). The inverse relation G^(-1) is the set shown below

{(3,5), (3,2), (4,6)}

All I've done is swap the (x,y) values for each ordered pair to form the inverse relation. As you can see, x = 3 leads to multiple y value outputs which is why this relation is not a function. So in short, the answer is choice C. To have the inverse relation be a function, each value in the original domain must map to exactly one value in the range only. However that doesn't happen as the domain values map to an overlapping y value (y = 3).

EMERGENCY! <br><br> How many cubes with side lengths of 1/2 cm does it take to fill the prism?
Sati [7]

Answer:

  24 cubes

Step-by-step explanation:

You can figure this a couple of ways.

I usually find it easiest to figure in terms of the number of cubes each dimension represents. The vertical dimension (3/2 cm) is the length of 3 cubes; the front-back dimension (2 cm) is the length of 4 cubes, and the width (1 cm) is the length of 2 cubes.

The total number of cubes required is the product of the dimensions in cube-lengths: 3×4×2 = 24 cubes.

__

Another way to figure this is to compute the prism volume in the given dimensions (cm³) and the cube volume in the same dimensions, then find the number of cube volumes in the prism volume.

  Prism volume = l×w×h = (2 cm)(1 cm)(3/2 cm) = 3 cm³

  Cube volume = (1/2 cm)³ = 1/8 cm³

Then the number of cubes that will fit in the prism is ...

  (3 cm³)/(1/8 cm³) = 3×8 = 24 . . . . cubes
