Rudolph and his 4 friends threw a party and evenly shared the cost. They spent $515 on food and $250 to rent the hall. The DJ played for 4 hours and charged them $175 per hour. How much did each friend contribute? SHOW YOUR WORK BELOW *

366.

Step-by-step explanation: $515 and $250 is $765. $175 times 4 hours of playing is $700. $700 Plus $765 is $1465. $1465 divided by 4 equals $366.25 from each friend.

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
