Answer:
-18
Step-by-step explanation:
So we have the expression:
[tex]a-6y[/tex]
And we want to evaluate it when y=2 and a=-6.
Substitute in these values:
[tex]=(-6)-6(2)[/tex]
Multiply:
[tex]=(-6)-12[/tex]
Subtract:
[tex]=-18[/tex]
Answer:
-18
Step-by-step explanation:
We are given the expression:
[tex]a-6y[/tex]
and asked to evaluate when a= -6 and y=2.
Therefore, we must substitute -6 in for a and 2 in for y.
[tex]a-6y , a=-6, y=2[/tex]
[tex](-6)-6(2)[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, and Subtraction.
Multiply 6 and 2.
[tex](-6)-(6*2)[/tex]
[tex](-6)-(12)[/tex]
[tex](-6)-12[/tex]
Subtract 12 from -6.
[tex](-6-12)[/tex]
[tex]-18[/tex]
The expression a-6y when evaluated for a=-6 and y=2 is equal to -18.
