How many solutions does this problem have Y=-2x -4 Y= 3x plus 3

Mathematics
1 answer:
S_A_V [24]2 years ago
7 0

Answer:

There is one possible solution

Step-by-step explanation:

Here, we want to get the number of solutions

We can proceed to solve the equation

we have two y values so we can directly equate the x parts

-2x - 4 = 3x + 3

3x + 2x = -3-4

5x = -7

x = -7/5

To get y, we substitute

We can only get one value of y too

So we have a point (x,y) as the solution to the system of equations

Write the fraction as a whole or mixed number.
Wewaii [24]

Answer:

1\frac{1}{2}

Step-by-step explanation:

If there is 1500 cellular phones per 1000 people, then the number of phones per person is:

\frac{1500}{1000} = \frac{15}{10} = \frac{3}{2}

Now we know that \frac{3}{2} = 1 + \frac{1}{2} = 1\frac{1}{2}

81 is 37.5% of what number?
laila [671]

Hi,

81 is 37.5% of 216.

"1. We assume, that the number 37.5 is 100% - because it's the output value of the task.  

2. We assume, that x is the value we are looking for.  

3. If 100% equals 37.5, so we can write it down as 100%=37.5.  

4. We know, that x% equals 81 of the output value, so we can write it down as x%=81.  

5. Now we have two simple equations:

1) 100%=37.5

2) x%=81

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=37.5/81

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81 is what percent of 37.5

100%/x%=37.5/81

(100/x)*x=(37.5/81)*x       - we multiply both sides of the equation by x

100=0.46296296296296*x       - we divide both sides of the equation by (0.46296296296296) to get x

100/0.46296296296296=x  

216=x  

x=216                          "

Have a great day!

Misty took a multiple choice test in science that had 50 questions. If the relationship between the number she got correct and t
Alex
In this case, the total number of questions in the test is 50. The possible outcome for the question would be answered wrong, answered correctly or not answered. To know the amount of the correct answer, you need to multiply the incorrect with correct/incorrect ratio. The equation would be:
correct answer: 9 answer * 7/3= 21 answer.

Then for this test misty has:
9 incorrect answer
21 correct answer
20 blank/ not answered
