</span><span>m=<span>7/2</span>,</span><span>b=−2</span><span> where m is the </span>slope<span> and b is the </span>y-intercept
Answer:
Step-by-step explanation:
Sure! So, we need to divide by 1.6 on each side to isolate the x.
1.6x / 1.6 is just x. We need to divide by the same on the other side too!
1.28 / 1.6 is 0.8.
So x = 0.8
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
