a contractor has at most $42 to spend on nails for a project. finishing nails cost $0.45 per pound and
common nails cost $0.60 per pound. he would like to purchase at least 30 pounds of nails total.
a. write a system of linear inequalities:
b. write two possible solutions:

Step-by-step explanation:

f(x)=42-0.45(x)  Solution 13.5 dollars expend in 30 Finishing nails

f(x)=42-0.60(x) Solution 18 dollars expend in 30 Common nails

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
