For what value of k is the line through the points (3, 2k + 1) and (8, 4k − 5) parallel to the x-axis?
(A) −1 (B) 3 (C) 2 (D) 0 (E) −4

B: 3

Step-by-step explanation:

For the line to be parrallel to the x-axis, it means the slope is zero.

Thus;

(y2 - y1)/(x2 - x1) = 0

(4k - 5 - (2k + 1))/(8 - 3) = 0

4k - 5 - 2k - 1 = 0

2k - 6 = 0

2k = 6

k = 6/2

k = 3

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
