### Subject: Basic Math

Find the prime factorization of 100 and 70 and then the prime factorization of 7000 knowing that 7000 = 100 × 70

Prime factorization of 100 and 70. 100 = 2 2 × 5 2 70 = 2 × 5 × 7 Use the fact that 7000 = 100 × 70 to find the prime factorization 7000. 7000 = 100 × 70 = (2 2 × 5 2) × (2 × 5 × 7) = 2 × 2 × 5 × 5 × 2 × 5 × 7 = 2 3 × 5 3 × 7

### Subject: Algebra

Find the slope of the lines through the given points and state whether each line is vertical, horizontal or neither. Line L1 : (-2 , 3) and (8 , 3) Line L2 : (4 , 3) and (4 , -3) Line L3 : (-1 , 7) and (3 , -3)

Apply the formula for finding the slope. Slope of line L1 = (3 - 3)/(8 + 2) = 0 , horizontal line. Slope of line L2 = (-3 - 3)/(4 - 4) = -6/0 undefined, vertical line. Slope of line L3 = (-3 - 7) / (3 + 1) = -10/3, L3 is neither horizontal nor vertical.
