Your grandfather purchased a house for $50,000 in 1952 and it has increased in value according to a function

y = v(x),

where x is the number of years owned. these questions probe the future value of the house under various mathematical models. (let x = 0 represent the year 1952.)

suppose the value of the house is $75,000 in 1962 and $120,000 in 1967. assume v(x) is a quadratic function. find a formula for v(x). (round your values to two decimal places.)

it would be 6xy and -16xy.

step-by-step explanation:

the answer is 128

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
