Answer:
You are not supposed to be cheating.
Step-by-step explanation:
Answer:
y=0.5x+4
Use y2-y1/x2-x1 to find the slope:
3-6/-2-4
Sub in the x and y-values into y=0.5x+b
6=0.5(4)+b
Solve and b=4
The part of the quadratic formula that dictates whether the function is factorable or not is B. b^2 - 4ac. This determines the number of real, imaginary, negative and positive roots.
In the equation <span>2x^2 + 7x + 3,
we use the quadratic formula
x = -b +- sqrt (b2 -4ac) /2a = -7 +- </span><span>sqrt (49 -24) /4
the answers are x1 =-0.5 and x2 = -3.</span>
