B because when you add .3 to 5 you get 5.3 and when you ad .3 to 5.3 you get 5.6 and so on
Answer:
-20
Step-by-step explanation:
Combine Like Terms:
=−12+−7k+6k+−8+k
=(−7k+6k+k)+(−12+−8)
=−20
Answer:F(x) = 2x-15
Step-by-step explanation:
combine like terms
Recall that given the equation of the second degree (or quadratic)
ax ^ 2 + bx + c
Its solutions are:
x = (- b +/- root (b ^ 2-4ac)) / 2a
discriminating:
d = root (b ^ 2-4ac)
If d> 0, then the two roots are real (the radicand of the formula is positive).
If d = 0, then the root of the formula is 0 and, therefore, there is only one solution that is real and of multiplicity 2 (it is a double root).
If d <0, then the two roots are complex and, in addition, one is the conjugate of the other. That is, if one solution is x1 = a + bi, then the other solution is x2 = a-bi (we are assuming that a, b, c are real).
One solution:
A cut point with the x axis
Two solutions:
Two cutting points with the x axis.
Complex solutions:
Does not cut to the x axis
