The answer of this problem is that you have to multiply 6 times 5 so the answer is 30 units3
Answer:
Infinitely many solutions.
Step-by-step explanation:
Given
![3x-2y=12\\ 6x-4y=24](https://tex.z-dn.net/?f=3x-2y%3D12%5C%5C%206x-4y%3D24)
Required;
Find the solution
![3x-2y=12 --(1)\\ 6x-4y=24 -- (2)](https://tex.z-dn.net/?f=3x-2y%3D12%20--%281%29%5C%5C%206x-4y%3D24%20--%20%282%29)
Make x the subject of formula in (1)
![3x-2y=12](https://tex.z-dn.net/?f=3x-2y%3D12)
Add 2y to both sides
![3x-2y+2y=12+2y](https://tex.z-dn.net/?f=3x-2y%2B2y%3D12%2B2y)
![3x=12+2y](https://tex.z-dn.net/?f=3x%3D12%2B2y)
Divide both sides by 3
![\frac{3x}{3}=\frac{12+2y}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B12%2B2y%7D%7B3%7D)
![x=\frac{12+2y}{3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B12%2B2y%7D%7B3%7D)
Substitute
in (2)
![6x-4y=24](https://tex.z-dn.net/?f=6x-4y%3D24)
![6(\frac{12+2y}{3})-4y=24](https://tex.z-dn.net/?f=6%28%5Cfrac%7B12%2B2y%7D%7B3%7D%29-4y%3D24)
![2(12+2y)-4y=24](https://tex.z-dn.net/?f=2%2812%2B2y%29-4y%3D24)
Open Bracket
![24+4y-4y=24](https://tex.z-dn.net/?f=24%2B4y-4y%3D24)

![0 = 0](https://tex.z-dn.net/?f=0%20%3D%200)
Based on the result above, the two equations have infinitely many solutions.
Answer:
first u should write like this 119/100
then that is the answer .
Step-by-step explanation:
For decimal point u should move 3 points left hand sight ...
so u got 0.119
hope my answer correct ... im not sure ...
Answer:
x = - 2 or x = 4
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
The x- intercepts are at x = - 2, x = 4
