Answer:
<h2>
A. ¹²/₅</h2>
Step-by-step explanation:
There is no solution for system of equations: 
if: 
so first, we we need to transform the equations to the form where the coefficients at y will be the same:
Now we have b₁=b₂ and c₁≠c₂ so the system has no solution if a₁=a₂
5k = 12
÷5 ÷5
k = ¹²/₅
Answer:
21 because -1/4a - 4 is 22
Sum of two integers with different signs is equal to 8.
There are several answers:
+12 and -4
+10 and -2
+11 and -3
ETC.
Answer:
Step-by-step explanation:
No...this is not a function.
A function will not have ANY repeating x values.....they can have repeating y values, just not the x ones.
And this set of numbers has repeating x values of 1
in other words, in a function, all the x values have to be different numbers....none can be the same
