Show that the system has no solution. x + 2y = -4 y = -1/2x - 4

Mathematics
1 answer:
erica [24]3 years ago
7 0

Step-by-step explanation:

TO show that this system has no solution, use the y value in the second equation and put it in for y in the first. Then solve.

x + 2y = -4

x + 2(-1/2x - 4) = -4

x  - x - 8 = -4

-8 = -4

Because this is an incorrect statement, we can tell there is no solution.

Solutions of the equation: z2 - 12z + 36 = 0?
jasenka [17]
36 becomes a negative 

First -36 + -1 -37
Next: -18 + -2 = -20 
Next: -12 + -3 = -15
Next: -9 + -4 which equals -13
Finally we get to the last part: -6 + -6 = -12

We change z2 to z^{2}

z^{2} - 6(z) = 36 

z(z) - 6

Because, we add up for the first two terms

Switch up, up the problem 6(z) - 6

Now, let's add the number 4 on the terms 
z - 6 (z - 6) 

Then, let's multiply z - 6 from z - 6 

z - 6^{2} = ? 


From this problem we have to add 6 from the sides that we are working with 

Therefore, your answer for z is 6

333 erasers cost \$4.41$4.41dollar sign, 4, point, 41. Which equation would help determine the cost of 444 erasers? Choose 1 ans
Rudiy27

Answer:

Option D will be correct.

Step-by-step explanation:

The 333 erasers cost $4.41.

We have to determine the cost of 444 erasers.

Let the price of 444 erasers is $x.

Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be \frac{333}{4.41} = \frac{444}{x}

⇒ \frac{3}{4.41} = \frac{4}{x}

Therefore, option D will be correct. (Answer)

Blank of 100 equals 16%
xxMikexx [17]
If you would like to solve blank of 100 equals 16%, you can calculate this using the following steps:

x of 100 equals 16%
x * 100 = 16%
x * 100 = 16/100      /100
x = 16/100 / 100
x = 0.0016

The correct result would be: 0.0016 of 100 equals 16%.
