Answer:
False,
(-4, -1) is not a solution of the given system of equations
Step-by-step explanation:
Given the system of equations:
.......[1]
......[2]
To determine (-4, -1) is a solution
Substitute x = -4 and y = -1 in both the equations, if they both satisfied then it is a solution.
⇒![-12-8 = 20](https://tex.z-dn.net/?f=-12-8%20%3D%2020)
⇒
False.
⇒![20-1 = 19](https://tex.z-dn.net/?f=20-1%20%3D%2019)
⇒
True.
Since, the given statement is not true
because the ordered pair (-4, -1) does not satisfy the given system of equations.
3y+6+8-6=-15
3y+8=-15
3y=-15-8
3y=-23
y=23/3 or 7.6

The winner got $70,000 and the runner up got $14,000
Let the winner be represented by x and runner up by y
Data given;
- Amount to be shared = $84000
- x = 5y
This is a simple case of ratio i.e 1 : 5
<h3>Equation</h3>
![x = 5y\\84000 = 5y + y\\84000 = 6y\\y = 14000\\](https://tex.z-dn.net/?f=x%20%3D%205y%5C%5C84000%20%3D%205y%20%2B%20y%5C%5C84000%20%3D%206y%5C%5Cy%20%3D%2014000%5C%5C)
The runner up received $14000. let's use this data to find how much the winner got.
![x = 5y \\x = 5 * 14000\\x = 70000](https://tex.z-dn.net/?f=x%20%3D%205y%20%5C%5Cx%20%3D%205%20%2A%2014000%5C%5Cx%20%3D%2070000)
From the calculations above, the winner got $70,000 and the runner up got $14,000.

Answer:
m(x)= 0 when X= 3
Step-by-step explanation:
2*3=6
6-6=0
For (2x-6)
3-4=-1
So -1*0=0
it can also be look at like this (0,-1)
