Question 940757: The steps to derive the quadratic formula are shown below:
Step 1: ax2 + bx + c = 0
Step 2: x2 + b over ax + c over a = 0
Step 3: x2 + b over ax = - c over a
Step 4: x2 +b over a x + square of quantity of b over 2 times a = - c over a + square of quantity of b over 2 times a
Step 5: x plus b over 4a, all square = - c over a+ square of quantity of b over 2 times a
Step 6: x + b over 2 times a = square root of all of negative c over a plus the square of the quantity b over 2 times a
Step 7: x = - b over 2 times a± square root of all of negative c over a plus the square of the quantity b over 2 times a = -b over 2 times a ± square root of the quantity of b squared minus 4 times a times c over 4 times a squared= negative b plus or minus square root of b squared minus 4 times a times c over 2 times a
Which of the following statements best describes the first incorrect step?

Question 940762: A quadratic function and an exponential function are graphed below. Which graph most likely represents the exponential function?
graph of function g of x is a curve which joins the ordered pair 0, 1 and 1, 2 and 3, 8 and 5, 32 and 6, 64. Graph of function f of x is a curve which joins the ordered pair 0, 1 and 1, 2 and 3, 10 and 5, 26 and 6, 37
1. f(x), because an increasing quadratic function will eventually exceed an increasing exponential function.
2. g(x), because an increasing exponential function will eventually exceed an increasing quadratic function.
3. f(x), because an increasing exponential function will always exceeds an increasing quadratic function until their graphs intersect.
4. g(x), because an increasing quadratic function will always exceeds an increasing exponential function until their graphs intersect.

Question 942419: Which of the following is a line which is perpendicular to the line 3x+7y+2=0?
The answer is 7x-3y+5=0
this is how I solve the problem.
3x+7y+2=0
y=-2/7-3x/7
-1/m= -1/-3/7=7/3
7/3= slope
y-y0=m (x-x0)
y=7/3(x-0)
y=7/3
bx+ay=0
7x+3y=0
Where did they get 7x-3y +5=0?
