Use order of operations, or PEMDAS which stands for Parenthesis, Exponent, Division, Addition, and Subtraction.
Do those operations in that order. Can you try?
What will be the first thing you do here, according to PEMDAS?
The supplement of <DCE is <ACE, remember, a supplementary pair is a pair of two angles whose sum of degrees sums up to 180 degrees.
The verticle angle to <BCD is <ACF. A verticle angle is formed when two lines intersect, there are four angles formed, the verticle angles are the angles opposite to each other, and verticle angles are congruent.
B. The domain and the range are all real numbers.
C. The domain is x>0. The range is f(x)>0.
D. The domain is all real numbers except 0. The range is all real numbers
If your function is (as written) ...
... f(x) = (2/3)x
Then B is the correct answer.
_____
If your function is ...
... f(x) = 2/(3x)
Then A is the correct answer.

The expression 3x + 7x - 28 + 31 - 8x simplifies to 2x + 3. When x equals 2043, the value of the Simplifying Expression is 4089.
The given expression is 3x + 7x - 28 + 31 - 8x.
To simplify the expression, we first group together the like terms.
Thus, the expression becomes (3x + 7x - 8x) + (31 - 28).
This simplifies further to 2x + 3.
Next, to find the value of the expression for x = 2043, we substitute 2043 for x into the simplified expression, resulting in 2*2043 + 3 = 4089.
Therefore, the simplified version of the expression is 2x + 3 and the value of the expression for x = 2043 is 4089.
