Answer:
y = ±
Step-by-step explanation:
Given
x = a - 2by² ( add 2by² to both sides )
x + 2by² = a ( subtract x from both sides )
2by² = a - x ( divide both sides by 2b )
y² = ( take the square root of both sides )
y = ±

Question 2:
<h3>Answer: Yes the number changes</h3>Taking the zero out of 10.25 leads to 1.25 which is definitely a different number (and smaller). Therefore, this zero is a significant digit compared to before.
Answer:
x = -14
Step-by-step explanation:
Let's solve your equation step-by-step.
4x + 188 = 6x +216
Subtract 6x from both sides:
4x + 188 - 6x = 6x + 216 - 6x
-2x + 188 = 216
Subtract 188 from both sides:
-2x + 188 - 188 = 216 - 188
-2x = 28
Divide both sides by two:
