Answer:
{-1, 2, 3}
Step-by-step explanation:
We need to find the values of x that correspond to these y-values.
{-4, -2, 4} = -2(x +1) +4 . . . substitute the range values for y
{2, 1, -2} = x +1 -2 . . . . . . .divide by -2
{2, 1, -2} = x -1 . . . . . . . . . simplify
{3, 2, -1} = x . . . . . . . . . . . add 1
The domain of the function is {-1, 2, 3}.
Answer:
909 times
Step-by-step explanation:
$500,000/550= 909
All you have to do is 1000 divide 231
You will get the answer 0.231
Than you move the decimal point 2 times to the right
So the percentage is 23.1%
Answer:
3
Step-by-step explanation:
So first, plugin y to your equation, it should look like this: 4x+x+5+20. Now, we can solve this. Next, we have two x's so we can combine them. The equation will now look like this: 5x+5=20. Now, we have an extra 5 laying around that we need to get rid of, so we can subtract that 5 to both sides of the equation and we get this: 5x-5=20-5 which ends up being 5x=15. Now, we just divide both ides by 5 and since 15 divided by 5 is 3, we get: x=3
4x-6x+18...... The -6x + 18 comes from distributing the -2.
-2x+18
