Answer: it will take 14 months for their weights to be the same.
Step-by-step explanation:
Let x represent the number of months it will take for their weights to be the same.
Katy weighs 105 pounds and is gaining 2 pounds a month. This means that the total weight of Katy after x months is
2x + 105
James weighs 175 pounds and is losing 3 pounds a
month. This means that the total weight of James after x months is
175 - 3x
For their weights to be the same, it means that
2x + 105 = 175 - 3x
3x + 2x = 175 - 105
5x = 70
x = 70/5
x = 14
Answer:
x=1.6 repeating. I hope this helped
Answer:
8
Step-by-step explanation:
A is on the negative side so you count the distanse as -6 -5 -4 so on and then you get to 0 and then its 12345678

Step-by-step explanation:
Answer:
.
Step-by-step explanation:
Let the smaller root to this equation be . The larger one will equal .
By the factor theorem, this equation is equivalent to
, where .
Expand this expression:
.
This equation and the one in the question shall differ only by the multiple of a non-zero constant. It will be helpful if that constant is equal to . That way, all constants in the two equations will be equal; will be equal to .
Compare this equation and the one in the question:
The coefficient of in the question is (which is omitted.) The coefficient of in this equation is . If all corresponding coefficients in the two equations are equal to each other, these two coefficients shall also be equal to each other. Therefore .
This equation will become:
.
Similarly, for the coefficient of ,
.
.
This equation will become:
.
is the value of the constant term of this quadratic equation.
