Question

Grandma Millie is shrinking! Her height decreases by 1/4 cm each year. What is her total change in height over 3 years?

Total change in her height is ¾cm

Step-by-step explanation:

At the end of each year, her height would have decreased by ¼cm

Now we have to determine the total change in her height over 3 years

If the height of Grandma decreases by ¼ in one year

The. Her height would decrease by 3 * ¼ in 3 years

3 * ¼

= ¾ cm

Thus, the total change in her height over 3 years is ¾

the circle one

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
