I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20
Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20

So that's how we're able to go from this
to this
The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.
Answer:
The answer to the equation is W’(4, –2), X’(3, –4), Y’(1, –4), Z’(0, –2)
Step-by-step explanation:
Because its turning 180 degrees that means its turning half the way it is. and if you look on the graph the z is Z (0, 2). which if you flip it upside down it would be (0,-2)
Also i took the test! :)
Answer:
I don't know where those answers are coming from, but I got:
23s - 145
Answer:
-2 1/5, -1 2/5, 1/5, |-3/5|, |-1 1/5| ,|-2 2/5|
Step-by-step explanation:
Absolute value means take the positive value
-2 1/5
|-1 1/5| = 1 1/5
|-2 2/5| = 2 2/5
1/5
|-3/5| = 3/5
-1 2/5
We want the numbers from smallest to largest
The most negative is
-2 1/5, -1 2/5
Then to the fractions
1/5, |-3/5|
Then the positive numbers
|-1 1/5| ,|-2 2/5|
