The price y for x pounds of nails at U-Fix-it is represented by y = 4.4x. The unit price for the same type of nails at Just Hardware is $0.30 per pound greater than the unit price at U-Fix-it. Complete the table to show the cost for 1, 2, 3, and 4 of pounds of nails at Just Hardware.

(Hint: y = 4.4x + 0.30,
y = 4.4(1) + 0.30 = $4.70 per one pound.
Substitute the number of pounds (x) and multiply by 4.4 then add 0.30.

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
