Answer:

we know that

16/4-----------> 8/2---------> 4/1

so

case 1) 

64/16--------> 32/8-----> 16/4------> 8/2------> 4/1

the quantity (64/16) is proportional to 16/4

case 2)

6/1 is not 4/1

so

the quantity (6/1) is not proportional to 16/4

case 3)

5/1 is not 4/1

so

the quantity (5/1) is not proportional to 16/4

case 4)

48*12--------> 24/6-----> 12/3------> 4/1

the quantity (48/12) is proportional to 16/4

case 5)

4/1 is equal to 4/1

so

the quantity (4/1) is proportional to 16/4

X+y+z=1
andrezito [222]

Answer: x = 0

y = 2

z = -1

Step-by-step explanation:

The system of equations are

x+y+z=1 - - - - - - - - - - 1

-2x+4y+6z=2 - - - - - - - - - 2

-x+3y-5z=11 - - - - - - - - - 3

Step 1

We would eliminate x by adding equation 1 to equation 3. It becomes

4y -4z = 12 - - - - - - - - - 4

Step 2

We would multiply equation 1 by 2. It becomes

2x + 2y + 2z = 2 - - - - - - - - - 5

We would add equation 2 and equation 5. It becomes

6y + 8z = 4 - - - - - - - - - 6

Step 3

We would multiply equation 4 by 6 and equation 6 by 4. It becomes

24y - 24z = 72 - - - - - - - - 7

24y + 32z = 16 - - - - - - - - 8

We would subtract equation 8 from equation 7. It becomes

-56z = 56

z = -56/56 = -1

Substituting z = -1 into 7, it becomes

24y - 24×-1 = 72

24y + 24 = 72

24y = 72 - 24 = 48

y = 48/24 = 2

Substituting y = 2 and z = -1 into equation 1, it becomes

x + 2 - 1 = 1

x = 1 - 1 = 0

Please help me with #12 pleaseee
lawyer [7]
The equation of a line can be expressed in slope intercept form as y = mx + b where m is the slope and b is the y-intercept. Horizontal lines have a slope of 0, so the equation is simply y=b.

The y value of the point given is -5, so the answer is y = -5.

James has a dog grooming service. He charges a flat rate of $50 per month, plus $10 per grooming. Bradly does not charge a month
solmaris [256]

Answer:

The numbers of grooming visits for which James and Bradly would charge the same amount is 2

Step-by-step explanation:

Let

w -----> the numbers of grooming visits

y ----> the charge in dollars

we know that

<em>James</em>

y=10w+50 ----> equation A

<em>Bradly</em>

y=35w ----> equation B

equate equation A and equation B

35w=10w+50

Solve for w

35w-10w=50

25w=50

w=2

therefore

The numbers of grooming visits for which James and Bradly would charge the same amount is 2
