Answer:
y=11
x=-4
Step-by-step explanation:
y =-x+7
2x-5y=-7
insert the first equation into the second like so...
2x+5x-35=-7
Now rearrange...
2x+5x=-7+35
Now solve...
7x=-28
Now incert x in any equation...
y=4+7
a is 3k^2
b is -12k
and c is 12
As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)
<u>We can see on the table:</u>
Two same input values with different outputs.
So this not a function
n = -9
Step-by-step explanation:-
Those two angles have the same measure, so you have
