Answer: 3x+y=-9
Step-by-step explanation:
Step 1 is distribute y+6 = -3(x+1)
y+6 =-3x-3
Mow you have to move your x over because standard form is Ax+By=C
y+6+3x =-3
Move your +6 by subtracting from both sides
3x+y=-9
$2.65
You can get this by subtracting the 7.35 from the 10.
10 - 7.35 = 2.65

Answer:
Becky completed the proof incorrectly.
Step-by-step explanation:
The only difference of the two proofs, at least what I can see, is the reason for step 2. Angie claims that it is the Definition of Supplementary Angles, while Becky claims Angle Addition Postulate.
The Definition of Supplementary Angles states that m∠A + m∠B = 180°.
While the Angle Addition Postulate states that m∠A + m∠B = m∠C.
Because the context used is that m∠AKG + m∠GKB = 180° and m∠GKB + m∠HKB = 180°, it would be using the Definition of Supplementary Angles.
So Becky is the one who is incorrect.
Answer:
Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
