Solve 3x − 5y = 17 9x − 15y = −4

1 answer:

6 0

This is a system of equations, which means that we can solve it using either the elimination method or the substitution method. I will show elimination:
9x - 15y = 51
9x - 15y = -4
The top equation is found by multiplying the first equation by 3.
If you subtract the equations, you will find that it says 0 = 55. This is incorrect, so this system of equations has no solutions.

Order the following integers from least to greatest.-41, -53, -73, -78 A. -78, -53, -73, -41 B. -78, -73, -41, -53 C. -73, -78,

The value of negative integers decreases the further we get from the 0 point on the number line.

Therefore, if we arrange the numbers in ascending order ignoring the negative sign, the numbers will be in descending order when the negative sign is included.

By the definition above, we can say that the smallest number of the lot is -78 and the largest one is -41.

The numbers can be ordered from least to greatest as shown below:

$-78,-73,-53,-41$

OPTION D is the correct answer.
