1=-20+x i just need yall to show me the work .

Let's solve your equation step-by-step.

−1=−20+x

Step 1: Simplify both sides of the equation.

−1=x−20

Step 2: Flip the equation.

x−20=−1

Step 3: Add 20 to both sides.

x−20+20=−1+20

x=19

Hope this helps. :)

y < -3

y < -3

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
