Elijah bought a $25$-pound bag of dog food. He feeds his dog $0.5$ of a pound of dog food each day. Elijah will buy another bag of dog food when there are $2$ pounds of food left over. Part A Use the drop-down menus below to create an equation that represents the situation, in which $d$ represents the number of days until Elijah buys another bag of dog food. $=$ Question 2 Part B How many days can he use the $25$-pound bag of dog food before he buys a new bag? Respond in the space provided. If your test is on paper, write your answer on the answer sheet.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
