Hello from MrBillDoesMath!
Answer: y = 2x - 7
Discussion:
Divide both sides of the equation by 2:
2y /2 = (4x-14)/2 = 4x/2 -14/2
or
y = 2x - 7
Thank you,
MrB
2x+3=3x-4
try to isolate the x term
you must do the same thing to both sides or else it won't be equal anymore
2x+3=3x-4
add 4 to both sides
2x+3+4=3x+4-4
2x+7=3x+0
subtract 2x from both sides
2x-2x+7=3x-2x
0+7=x
7=x
the answer is x=7
Answer: Choice C. p = 250(0.79)^t
Work Shown:
p = a*b^t
p = a*(1+r)^t
p = 250*(1+(-0.21))^t
p = 250(0.79)^t
Note that r = -0.21 is negative to indicate we have exponential decay.
After solving the given problem, I’ve been able
to get 3(x-2) / 2(x-3) as the simplified form of the given
equation. I am hoping that this answer has satisfied your query and it
will be able to help you, and if you would like, feel free to ask another
question.

A) 22°
- Step-by-step explanation:
∡DBG = (360° - BD - BG)/2
= (360° - 170° - 146°)/2
= 44°/2
= 22°
