The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. If the veterinarian gives a 30-pound dog milligram of the medicine, which equation relates the weight, w, and the dosage, d?

Answers

Answer 1

Answer: If you would like to know which equation relates the weight and the dosage, you can find this using the following steps:

30-pound dog ... 1 milligram of the medicine
w pound dog ... d milligram of the medicine

30 * d = 1 * w
30 * d = w

The correct result would be 30 * d = w.

b.perpendicular
c.neither

Answers

The slope:
m = rise / run;
For the line segment AB:
m AB = (y 2 - y 1) /(x 2 - x 1) = ( f - 0 ) / ( e - 0 ) = f / e
For the line segment CD:
m CD = ( 0 - e ) / ( f - 0 ) = - e / f
m CD = - 1 / m AB

4x – 6 = −3x + 8

Answers

4x - 6 = -3x + 8

Add 3x to each side: 7x - 6 = 8

Add 6 to each side: 7x = 14

Divide each side by 7: x = 2

4x – 6 = −3x + 8

4x + 3x = 8 +6
7x = 14
x = 2

Answer: x < 4.6 rounded to the tenths

Step-by-step explanation:

3.8x + 14.5 < 32

subtract 14.5 on both sides.

3.8x < 17.5

divide by 3.8 on both sides.

x < 4.60526316
