Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-2x + 1 = -4x + 9
Step 2: Solve for <em>x</em>
- Add 4x to both sides: 2x + 1 = 9
- Subtract 1 on both sides: 2x = 8
- Divide both sides by 2: x = 4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-2(4) + 1 = -4(4) + 9
-8 + 1 = -16 + 9
-7 = -7
Answer:
3 ≤ x ≤ 4
Step-by-step explanation:
Step 1: Add 10 to all parts/sections.
Step 2: Divide all parts/sections by 3.
Therefore, the answer is 3 ≤ x ≤ 4.
The answer is c because 8 - 5 is 3.
Answer:
Option D
∠GDE is supplementary to ∠DEF and also supplementary to ∠FGD
Step-by-step explanation:
To use the supplementary property to identify a parallelogram. The condition must be that that the same-side interior angles (consecutive angles) are supplementary.
Thus for parallelogram DEFG
D --------------------E
/ /
G---------------------F
Thus, we have it that the condition that is most sufficient to show that quadrilateral DEFG is a parallelogram is
∠GDE is supplementary to both ∠DEF and ∠FGD
