2 x + y equals negative 9

Mathematics
1 answer:
Vilka [71]3 years ago
6 0

Answer:

The given equation which is in two variable is

 ⇒2 x + y =9

As we know that to get a unique solution you need two intersecting lines.

But here only one line is given.

On a single line there lie infinite number of points.

So, for different values of x we get different values of y or different values of y we get different values of x.

So , we can write the above equation as

either ⇒y=9-2 x Or x=9-2 y

I have drawn graph for you.

Thus , there are infinite number of solution of this equation. Like (0,9),(1,7),(2,5),(-2,13),(-1,11),(-3,15)......

Answer:

Step-by-step explanation:

When you roll dice, there are 6 possible outcomes.  

In order to not roll a 6, you'd have to roll either 1,2,3,4,5.

So you have a 5:6 chance of not rolling a 6.

But they're asking you to use the chart.

Based on the chart, you've rolled the die 24+10+8+3+30+15=90 times.

Of those 90 times, you rolled a 6 15 times.

Which means you did not roll a 6 90-15=75 times.

Therefore the probability of not rolling a 6, based on the chart, is 75/90=83%.

Notice that 5/6=83% as well.  So this chart is fairly accurate.

Now for number 2.

Based on the chart, odd numbers appear 24+8+30=52 times out of the 90.

So we can say that odd numbers show up 52/90=58% of the time.

If James is rolling the cube 250 times, we know odd numbers will show up 58% of the time so, .58*250=144 is how many times we can expect to see an odd number appear.

Answer:

$62

Step-by-step explanation:

I think there is some missing information. Primarily what the price of the 'Viola' is. Also, I think there might be something else missing, since the obvious answer would be the highest value  $62.00

Answer: Choice B

(-1,0), (-1,-2), (-3, -1), and (-3, -2)

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

Explanation:

Let's focus on the point (2,0)

If we shift it 3 units to the left, then we subtract 3 from the x coordinate to get 2-3 = -1 as its new x coordinate. The y coordinate stays the same.

That means we move from (2,0) to (-1,0)

Based on this alone, choice B must be the answer as it's the only answer choice that mentions (-1,0).

If you shifted the other given points, you should find that they land on other coordinates mentioned in choice B.

If we made it into a ratio of residential customers to business customers, it would be a 2:1

350/2 = 175

350 + 175 = 525

Answer:

x = -15/2

Step-by-step explanation:

For this problem, we will simply use equation properties to solve for x.

2x - 5 = -20

2x - 5 + 5 = -20 + 5

2x = -15  ( Add positive 5 to both sides )

2x * (1/2) = -15 * (1/2)

x = -15/2  ( Multiply both sides by 1/2)

Hence, the solution to x is -15 / 2.

Cheers.
