Which pair of lines are perpendicular? y = -4x + 1 and 8x + 2y = -10

x = 4 and y = -1

y = -8 and y = 2

x - y = 7 and y = x + 3

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

i have no idea just need points sorry

step-by-step explanation:

answer: a) 56% women

b)44% men

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
