Hey there!
3.9 times 10 to the seventh power is equivalent to the equation 3.9 ×
The seventh power indicates the amount of times the decimal moves to the right of 3.9, so that expression would be equivalent to 39,000,000.
Hope this helps!
Stretches are by the number in front of the x^2 hence the widest is least stretched (-x^2), then -4.5x^2 and lastly 6x^2
The equation to calculate the coordinates of point B is (b) 3 = √(x - 4)²+(y - 2)²
<h3>How to determine the equation?</h3>
The given parameters are:
A = (4,2)
AB = 3
The distance formula is:
AB = √(x - x1)²+(y - y1)²
So, we have:
3 = √(x - 4)²+(y - 2)²
Hence, the equation to calculate the coordinates of point B is (b) 3 = √(x - 4)²+(y - 2)²

Answer:
Step-by-step explanation:
n=12
-2n=12*3
n=36/-2
n=-18
120+.5x=50+.7x
Subtract 50 from both sides and then subtract .5x from both sides to get 70=.2x. Then divide both sides by .2 to get x=350.
