Answer:

x=-1

Step-by-step explanation:

Answer:

Please find attached the required graph created with Microsoft Excel

4. The solution is x = -1, y = -2

5. Both equations represent the same line and the system of equation has Infinitely many solutions

6. The system of equation represent two parallel lines, therefore, the system of equation has no solutions

Step-by-step explanation:

4. The given system of equation are;

y = -3·x - 5...(1)

y = 9·x + 7...(2)

Equating both values of y from the two equations, gives;

9·x + 7 = -3·x - 5

12·x = -5 - 7 = -12

x = -12/12 = -1

x = -1

y = 9·x + 7 = 9 × (-1) + 7 = -2

y  = -2

5. y = -2·x - 5...(1)

6·x + 3·y = -15...(2)

Substituting the value of 'y' from equation (1) in equation (2), gives;

6·x + 3·y = 6·x + 3 × (-2·x - 5) = -15 = -15

Therefore, equations (1) and (2) are the same and has infinitely many solutions

6. y = -4·x + 3

8·x + 2·y = 8

Substituting the value of 'y' from equation (1) in equation (2), gives;

8·x + 2·y = 8·x + 2×(-4·x + 3) = 6

However, 8·x + 2·y = 8, therefore, equations (1) and (2) do not intersect and they have no common solution.

Answer:

-7, but it doesn't make sense bc age can't be a negative. But based on how this is said it sounds like -7

Step-by-step explanation:

paloma's age = p

2( p + 15 ) = 16

2p + 30 = 16

        -30   -30

2p = -14

/2        /2

p = -7

Answer:

2250

Step-by-step explanation:

2 tons = 4000

4000 - 1750 = 2250

Hope this helps!!!

2250 pounds of weight remains.

The weight of an object exists as the force acting on the object due to gravity. Some standard textbooks determine weight as a vector quantity, the gravitational force acting on the object. Others describe weight as a scalar quantity, the magnitude of the gravitational force.

As we know that ,

1 tons =  2000 pounds

2 tons = 4000 pounds

therefore,

4000 - 1750 = 2250

Answer:  D) 18

======================================================

Explanation:

|-11| simplifies to 11

|-7| simplifies to 7

Whatever is inside the absolute value, you just remove the negative and that's the result of that absolute value expression. It represents the distance on a number line. So for instance -11 is 11 units from 0, which is why |-11| = 11.

Overall,

|-11| + |-7| = 11 + 7 = 18

Answer:

-2

Step-by-step explanation:

Answer:

-2 > -4

-2 is higher on the number scale

EQUATION:

[tex]y = \frac{k}{x} [/tex]

––––––––

First, find the constant of variation k using the formula k=xy.

[tex]23 = \frac{k}{8} [/tex]

[tex]k = (8)(23)[/tex]

[tex]k = 184[/tex]

––––––––

Then, find y if x is equal to four using the formula y=184/x.

[tex]y = \frac{184}{x} [/tex]

[tex]y = \frac{184}{4} [/tex]

[tex]y = 46[/tex]

Answer:

4

Step-by-step explanation:

divide 18 by 72

First, you need to circle 2.75. You have to decide whether or not to shade it in. On this equation, you wouldn't, because the answer can't be 2.75. You can tell because its greater than, and not greater than or equal to. So leave the circle empty. Then, you have to decide which way to shade. On this equation, you would shade right simply because g has to be greater than 2.75. If it was less than, you would shade left. Hope this helped!!!

Draw out a number line. Make sure the numbers 2 and 3 are plotted on the number line. Between these two values, cut this area into 4 equal slices. After cutting into quarters, mark the 3rd quarter since 3/4 = 0.75, so this where the value 2.75 resides.

Plot an open circle at 2.75, then shade to the right. The open hole is to say "do not include this value as part of the solution set". So we're visually describing all values larger than 2.75

Refer to the diagram below.

Answer:

Option B

Step-by-step explanation:

By the midsegment theorem,

"Midsegment of a trapezoid is half the sum of the parallel bases"

By this theorem,

y + 6 = [tex]\frac{1}{2}[(3y-7)+(y+3)][/tex]

2(y + 6) = (3y + y) +(-7 + 3)

2y + 12 = 4y - 4

2y - 4y = -12 - 4

-2y = -16

2y = 16

y = 8

Therefore, length of the midsegment = y + 6

                                                              = 8 + 6

                                                              = 14

Option B will be the answer.

Answer:

x = 11.3125

Step-by-step explanation:

0.25 + 13 = 4(x - 8)

Distribute the 4 across the parentheses.

0.25 + 13 = 4x - 32

Combine the constants on the left side of the equal sign.

13.25 = 4x - 32

Combine all the constants by adding 32 to both sides.

45.25 = 4x

Divide by 4 to isolate the x.

45.25/4 = x

11.3125 = x

Check.

0.25 + 13 = 4(x - 8)

0.25 + 13 = 4(11.3125 - 8)

0.25 + 13 = 4(3.3125)

0.25 + 13 = 13.25

13.25 = 13.25
