he factorization of x2 + 3x – 4 is modeled with algebra tiles. An algebra tile configuration. 2 tiles are in the Factor 1 spot:

1 is labeled + x, 1 is labeled negative. 5 tiles are in the Factor 2 spot: 1 is labeled + x and 4 are labeled +. 10 tiles are in the Product spot: 1 is labeled + x squared, 1 is labeled negative x, the 4 tiles below + x squared are labeled + x, and the 4 tiles below the negative x tiles are labeled negative. What are the factors of x2 + 3x – 4? (x + 4) and (x – 4) (x + 3) and (x – 4) (x + 4) and (x – 1) (x + 3) and (x – 1)

How many positive factors of 200 are divisible by 4?
Stella [2.4K]

Answer:

C. 6, D. 20, B. 18, B. 9

Step-by-step explanation:

#1. Factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100 & 200, of which 6 are divisible by 4 (4, 8, 20, 40, 100 & 200)

#2. Prime factors of 35 are 7 & 5, twice the sum of these factors, k = 24. k-4 = 20

#3. Non-multiples of 4 nor 5 between 16 and 45 are 17, 18, 19, 21, 22, 23, 26, 27, 29, 31, 33, 34, 37, 38, 39, 41, 42 & 43...thus 18 non-multiples

#4. Even factors of 120 greater than 1 and less than 40 are 2, 4, 6, 8, 10, 12, 20, 24 & 30...thus there are 9 even factors

Which expression can be simplified to find the slope of the trend line in the scatterplot? On a coordinate plane, a line goes th
Goryan [66]

Answer:

(A)\dfrac{24-79}{12-2}

Step-by-step explanation:

Given the trend line which goes through (2, 79) and (12, 24).

Slope, m=\dfrac{y_2-y_1}{x_2-x_1} \\x_1=2, y_1=79,x_2=12, y_2=24\\$Therefore$:\\\\m=\dfrac{24-79}{12-2}

The equation which can be simplified to find the slope of the trend line in the scatterplot is \dfrac{24-79}{12-2}

The correct option is A.
