we have that

y = 3x + 5

and that

z = x² + 2x - 5

we want to know what yz or y·z is equal to

we have what y and z are equal to so we can multiply them together

(3x+5)(x²+2x-5)

first we multiply each value in the second set of parentheses by 3x and then multiply each value in the second set of parentheses by 5 and then combine like terms.

(3x+5)(x²+2x-5)

3x³+6x²-15x + 5x² +10x -25

3x³ + 11x² -5x -25

so your answer should be

D) 3x³+11x²-5x-25

Which of the following correctly justifies statement 4 of the two-column proof?
slavikrds [6]

Answer:

D.Transitive property of equality

Step-by-step explanation:

We are given that segment JK is parallel to segment LM

We have to prove \angle 3=\angle 6

We have to find which option correctly justifies the statement 4 of the two - column proof.

1.Statement : JK is parallel to segment LM

Reason: Given

2.\angle 7\cong \angle 6

Reason: Vertical angles theorem

3.\angle 3\cong \angle 7

Reason:Corresponding angles theorem

4.\angle 3\cong \angle 6

Reason: Transitive property of equality.

If a=b and b=c then a=c

Hence, option D is true.

9514 1404 393

Answer:

  1. x ≤ 4
  2. x > 10
  3. x ≤ -7

Step-by-step explanation:

We're guessing you want to solve for x in each case. You do this in basically the same way you would solve an equation.

1. 3x +2 ≤ 14

  3x ≤ 12 . . . . . subtract 2

  x ≤ 4 . . . . . . . divide by 3

__

2. -5 +2x > 15

  2x > 20 . . . . . . add 5

  x > 10 . . . . . . . . divide by 2

__

3. -2x +4 ≥ 18

  4 ≥ 18 +2x . . . . . add 2x

  -14 ≥ 2x . . . . . . . subtract 18

  -7 ≥ x . . . . . . . . . divide by 2

<em>Additional comment</em>

The statement above that the same methods for solving apply to both equations and inequalities has an exception. The exception is that some operations reverse the order of numbers, so make the inequality symbol reverse. The usual operations we're concerned with are <em>multiplication and division by a negative number</em>: -2 < -1; 2 > 1, for example. There are other such operations, but they tend to be used more rarely for inequalities.

You will note that we avoided division by -2 in the solution of the third inequality by adding 2x to both sides, effectively giving the variable term a positive coefficient. You will notice that also changes its relation to the inequality symbol, just as if we had left the term where it was and reversed the symbol: -2x ≥ 14 ⇔ -14 ≥ 2x ⇔ x ≤ -7 ⇔ -7 ≥ x
