Regina is comparing the cost to rent a car from four different companies. she found that the cost to rent from each company can be modeled by a linear function of the number of miles driven. the formulas for each company are shown in the table. daily cost to rent a car driven x miles company cost in dollars 1 3 4 which statement is best supported by the table? company 1 and company 4 charge the same rate per mile. company 2 and company 3 charge the same rate per mile. company 2 charges only a flat fee and does not charge per mile. company 3 charges only a flat fee and does not charge per mile.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
