Joshua found that the equation -2|-x|-6 = -12 had to possible solutions X=5 and X= -11 Which explains whether his solutions are correct he's correct because both solutions satisfy the equation he is not correct because he made a sign error he is not correct because there are no solutions he's not correct because they're only one solution: X=5

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

t= 1/3.

hope this .

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
