  • Each trials has two possible outcomes. Success or failure.
  • The probability of success is same in very trail.

Rewrite the polynomial in the form ax^2 + bx + C and then identify the values of a, b, and c.
sergejj [24]

Answer:

a = 5\\\\b = -1\\\\c=1

Step-by-step explanation:

Given

-x+5x^2+1

Required

Rewrite and identify a, b and c

The required form is:

ax^2 + bx + c

Equate both expressions

ax^2 + bx + c = -x+5x^2+1

Rewrite as:

ax^2 + bx + c = 5x^2-x+1

Compare the expressions on either sides

a = 5\\\\b = -1\\\\c=1

I need this due by tonight what is 45+x=75
vladimir1956 [14]

Given: \textsf{45 + x = 75}

Need:  \textsf{The value of the unknown x}

Solution:  In order to solve for the unknown we must subtract 45 from both sides which would isolate x and given us the value.

<u>Subtract 45 from both sides</u>

  • \textsf{45 - 45 + x = 75 - 45}
  • \textsf{x = 75 - 45}
  • \textsf{x = 30}

After simplifying the expression we were able to determine that x is equal to 30.
