write an equation for the line that passes through (5,-4) and is perpendicular to the graph of 5x -2y=-6

Vadim26 [7]

Answer:

y = (-2/5)x - 2

Step-by-step explanation:

One way to attack this problem is to interchange the coefficients of x and y and change the sign of one to +: 5x - 2y = -6 becomes 2x + 5y = c. Solving for the slope, m, we get 5y = -2x + c first, and then y = (-2/5)x + D.

Subbing 5 for x and -4 for y, we now have -4 = (-2/5)(5) + D.

Then -4 = -2 + D, so that D = -2.

The desired equation is thus y = (-2/5)x - 2.

Check: Does this pass through (5, -4)? Is -4 = (-2/5)(5) - 2 true? Yes.

Is the slope -2/5 the negative reciprocal of 5/2? Yes, it is.

5. 3x-X-7=3 6.3x-3-X=3 7. -1 - 2x +3x=5 8. 3x - 22 - X=6 9. 2x+3x-10=10

Marta_Voda [28]

** 3x - x -7 = 3

2x = 10

x = 5

** 6. 3x - 3 -x = 3

18x - 3 - x = 3

17x = 6

x = $\frac{6}{17}$

** 7. -1 - 2x + 3x = 5

-7 - 2x + 3x = 5

-7 + x = 5

x = 12

** 8. 3x - 22 - x = 6

24x - 22 - x = 6

23x = 28

x = $\frac{28}{23}$

** 9. 2x + 3x -10 = 10

18x + 3x - 10 = 10

21x = 20

x = $\frac{20}{21}$

Find the domain and range of the function represented by the graph. Select all that apply.

Sveta_85 [38]

Answer:

Domain: [-2, 0, 2, 4]

Range: [3]

Step-by-step explanation:

The domain of the function are all values of x that are plotted on the horizontal axis (x-axis), while the range are the corresponding y-values plotted on the vertical axis (y-axis).

Therefore,

Domain of the function = [-2, 0, 2, 4]

Range of the function = [3] (only 1 possible value of y can be seen as plotted on the gray]
