Find the Greatest Common Factor (GCF)

GCF = 2xy

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2xy(8x^3y/2xy + -8x^2y/2xy + -30xy/2xy)

Simplify each term in parenthesis

2xy(4x^2 - 4x - 15)

Split the second term in 4x^2 - 4x - 15 into two terms

2xy(4x^2 + 6x - 10x - 15)

Factor out common terms in the first two terms, then in the last two terms;

2xy(2x(2x + 3) -5(2x + 3))

Factor out the common term 2x + 3

<u>= 2xy(2x + 3)(2x - 5)</u>

Lim wrote several pairs of values that he thought were equivalent. Which of his equations is correct?
Annette [7]

Answer:

I believe the correct answer would be A: 3/5 = 60

Step-by-step explanation:

Firstly, the second option is wrong because 0.06 would be 6 hundredths, so that is wrong, the third option would be incorrect because 0.002 would equal 2 thousandths so that is also wrong, and the fourth option would be 25% instead of 75%, so your answer should be A.

  • Symmetric property of equality

#6

  • ∠A = ∠A
  • Reflexive property of equality

#7

  • If 2x - 5 + 3x = 10 ⇒ add up 2x and 3x ⇒ then 5x - 5 = 10
  • Associative property of addition

Answer:

C. \frac{4}{5}

Step-by-step explanation:

In order to find the slope knowing two points, use the slope formula \frac{y_2 - y_1}{x_2-x_1}. x_1 and y_1 represent the x and y values of one point the line intersects, and x_2 and y_2 represent the x and y values of another point the line intersects.

Knowing this, use the points (-4, -4) and (6, 4) for the formula. Substitute -4 for x_1, -4 for y_1, 6 for x_2, and 4 for y_2. Then, simplify:

\frac{(4) - (-4)}{(6) - (-4)} \\= \frac{4+4}{6+4} \\= \frac{8}{10} \\= \frac{4}{5}

Thus, \frac{4}{5} is the slope of the line.
