Mathematics
1 answer:
dedylja [7]3 years ago
7 0

Answer:

1. y = -2x + 5

2.  y = 3/5x + 5

3. y = -4/5x - 4

4. y = - 1

5. yes

6. yes

7. yes

8. no

Step-by-step explanation:

1.   (4,-3) parallel to y= -2x

     -3 = -2(4)+b

     b=5

2. (-5,2) parallel to y = 3/5x

    2= 3/5(-5)+b

     b=5

3. (-5,0) -4/5x

   0 = -4/5(-5)+b

    b = -4

4. (-4,-1)

    y= -1

5. yes

6. yes

7. yes

8. no

  • Same slope = parallel ex. y = -5x +7, y = -5x +12
  • opposite reciprocal  = perpendicular ex. y = -5x +7, y = 1/5x + 12
  • to find "b" with slope and point

          (x,y)  y = mx + b

          plug in the y value and x value in the eqaution and m=slope, solve for b

-11.3 is rational or irrational ? explain? 0.083 and 2.1371938 to please if its not much to ask?
zloy xaker [14]
Ignore the - sign for now.   11.3   =   11.3        113
                                                         -------  = ----------
                                                             1             10

Since this is the ratio of two integers, 11.3 is rational.  So is 11.3.

                                                                             83
If you really mean   <span>0.083, this is rational:  it is ---------
                                                                            1000

If y ou meant </span><span>0.083333333 ... , that's also rational:  1/12 is equivalent.</span>

garri49 [273]

Answer:

1/19

Step-by-step explanation:

3(7) -2 = 19, this would be g(7) but they want g^-1 (7) so you need the inverse of your answer:
1/19.

How to find the area of a square ABC D
____ [38]

Answer:

The answer to your question is 13 u²

Step-by-step explanation:

We know that the small triangle is surrounded by right triangles so we can use the Pythagorean theorem to find the lengths  of the small triangle

                 AD² = 3² + 2²

Simplify

                 AD² = 9 + 4

                 AD² = 13

                 AD = \sqrt{13}

Find the area of the square

Area = side x side

Area = AD x AD

Area = \sqrt{13} x \sqrt{13}

Area = 13 u²
