Answer:
The solution to the system of equations is x=3 y= 23
Step-by-step explanation:
solving this system of equation using substitution method
-3x-y=14 ….. equation (1)
-9x =-27 ….. equation (2)
Solving for value of x from equation 2
-9x =-27
so x= -27/-9 = 3
so x = 3
The second equation is solved for x, so we can substitute the expression 3 in for x in the first equation (1)
-3x-y=14
-3 (3) - y =14
-9-y= 14
-9=14+y
y=-23
The solution to the system of equations is x=3 y= -23
We can check our work by plugging these numbers back into the original equations. Let's try -3x-y=14
-3x-y=14
-3(3) -(-23)= 14
-9+23 = 14
14= 14
Yes, our solution checks out.
Answer:
Right-angle triangle
Step-by-step explanation:
Answer:
A function must be "one-to-one" in order to be invertable meaning that each y-value is associated with only one x-value. You can easily check to see if a function is invertable by using the "horizontal line test" where you run your finger up and down the graph and if at any point your finger is touching two or more points the graph has failed the test.
A, you need to plug in to start solving
The answer to your question is
add 8
when you add 8 to -11 it goes to -3 and when you add 8 to -3 it goes to 5 and so on and so on.
