In the 16000 a blacksmith good make a living by hand 14 horses shoes and nails a diligent blacksmith could make one horseshoe in 12 minutes And a nail in one minute in the 16000 it would take the blacksmith 220 minutes to complete a particular job with advances in technology the blacksmith was able to make a horseshoe in nine minutes in a day now on 42nd and could complete the same job and 155 minutes In the equations below H represents the number of horseshoes in the job and n represents the number of nails in the job

c

-by-step explanation:

it would be c

try soting them out first

step-by-step explanation:

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5

we have been given a piecewise function which has three parts

we can graph each part one by one.

first part is x+1 which is just like equation y=x+1

restriction with first part is x< 0 so that means we can use any number for x which is less than 0 for example x=-1 and x=-2

now plug x=-1 into y=x+1 to get y

y=x+1=-1+1=0

so the point will be (-1,0)

similarly we get another point (-2,-1)

now we graph a line joining both points but keep in mind that line must be on left side of x=0 because of restriction x< 0

same way we can graph 2nd and third parts

if we have < or > then we use open circle.

if we have < = or > = then we use close circle.

so using above information, final graph can be drawn as:
