Solve for y.
-6y=-18
Simplify your answer as much as possible.

y=3

Step-by-step explanation:

Isolate the unknown variable:

-6y/-6=-18/-6

Since both the denominator and numerator are negative, the result will be positive:

y=3

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
