Mathematics
1 answer:
trasher [3.6K]2 years ago
4 0

Step-by-step explanation:

9. a)

2•(-2) = 2 - 6

-4 = -4

-2 -2 = -2•2

-4 = -4

Yes, the ordered pair is the solution

9. b)

-1 = 3•(-2) +5

-1 = -6 +5

-1 = -1

3•(-2) +(-1) = -2

-6 -1 = -2

-7 ≠ -2

No, the ordered pair is not the solution

10. (-1, -1) and (3, -1)

11.

y = 6 +x

Now substitute it in the first equation:

3•(6 +x) = 5x

18 + 3x = 5x

18 = 2x

x = 18/2

x = 9

Now, substitute x = 9 in the second equation:

y -9 = 6

y = 6 +9

y = 15

Help anybody has an answered for this?
umka21 [38]

Answer:

Step-by-step explanation:

The correct domain consists of only five integers:  {0, 1, 2, 3, 4}  It's possible that the customer buys NO melons; that's why we have that 0 in the domain.  No customer may buy more than 4 melons; that's why the domain does not include numbers greater than 4.  Only whole melons are sold, which is why the domain contains no fractions, no mixed numbers.

Viktor [21]

Answer:

1 min 45 sec

Step-by-step explanation:

First convert 14 min to seconds.

14 x 60 = 840s

Now we can use ratios to find the answer

840s : 800m

Divide both sides by 8

105s : 100m

105s is 1 minute and 45 seconds

Harrizon [31]
the answer should be letter A

the difference of 3.4 and 1.25 = 2.15

Now you know that there will be 2 whole blocks and .15 of a block

.15 is equal to 3/20 which is equal to 15/100.

So you will have 2 whole blocks and 15/100 of a blocks. So the answer is A

What is the slope of the line that passes through the points (1, -6)(1,−6) and (-8, 9) ?(−8,9)?
Monica [59]

Answer:

The answer to your question is  m = -5/3      

Step-by-step explanation:

Data

Point 1 = (1, -6)

Point 2 = (-8, 9)

Process

To find the slope just substitute the values in the formula and simplify.

Formula

slope = m = (y2 - y1) / (x2 - x1)

-Identify x1, y1, x2 and y2

  x1 = 1    y1 = -6   x2 = -8  y2 = 9

-Substitution

             m = (9 + 6) / (-8 - 1)

-Simplification

             m = 15/-9

-Result

             m = -5/3
