<u>Answer</u>:
Therefore has one solution.
<u>explanation</u>:
Given equations:
6x + y = -7
-24x -7y = 25
Make y the subject:
6x + y = -7
y = -7 - 6x ..............equation 1
-24x -7y = 25
-7y = 25 + 24x
y = (25 + 24x)/-7 ..........equation 2
Solve them simultaneously:
(25 + 24x)/-7 = -7 - 6x
25 + 24x = -7 (-7 - 6x)
25 + 24x = 49 + 42x
42x - 24x = 25- 42
18x = -24
x = 
Then y is:
y = -7 - 6x
y = -7 - 6( )
y = 1
Has one separate value of x and y: ( , 1 ); so it has one solution.
20 divided by 12 would be 12 and 4 for the greatest common factor so in simplistic form you would get 1 2/3. I hope I got the answer correct.....
Answer:
Option 2, (y = 4/6x - 4)
Step-by-step explanation:
Knowing that m acts as the slope in general, we can conclude that part of the equation is as such:
y = 4/6x
Now we are given coordinate (0, - 4) so that here x = 0 and y = - 4. Let's substitute these values into the prior equation:
y = 4/6x
-4 = 4/6(0)
-4 = 0
Now in order for y (-4) to be equal to the opposite side of the equation you would have to add -4:
-4 = 0 - 4
-4 = -4
That would mean the equation represents:
y = 4/6x - 4
Answer:
they aren't the same ratio
Step-by-step explanation:
ratio of 5:10 then 9:15
5/10 and 9/15
and that is simplified
2.5/5 and 3/5 so they aren't the same ratio
If they have no other common factors other than one, the LCM is equal to the product of the two numbers.
For example, the factors of 3 are 3 and 1 and the factors of 10 are 1, 2, 5, and 10. Since they share no common factors other than one, the LCM is equal to 3*10= 30.
