Answer:

C) -3 x2 + 6

Step-by-step explanation:

Given algebraic expressions are:

  • \[2x^{2}+3x-4\]
  • \[8-3x\]
  • \[-5x^{2}+2\]

Adding the given expressions:

\[2x^{2}+3x-4 + 8-3x + (-5x^{2}+2)\]

Simplifying:

\[2x^{2}-5x^{2}+3x-3x-4 + 8 + 2\]

\[= (2-5)x^{2}+(3-3)x+(8 -4 + 2)\]

\[= -3x^{2}+6\]

Among the given options, this is equivalent to option C.

Can someone explain the quadratic formula please?
brilliants [131]

Answer:

While factoring may not always be successful, the Quadratic Formula can always find the solution. The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

If P(A)=0.4, P(A and B)=0.2,and P(A or B)=0.5, What is P(B)
Vladimir [108]

Answer:

\boxed{\ P(B)=0.3 \ }

Step-by-step explanation:

Hi,

We know that

P(A or B)=P(A)+P(B)-P(A and B)

so P(B)= P(A or B) - P(A) + P(A and B)

so

P(B) = 0.5 - 0.4 + 0.2 = 0.3

thanks
