X= -5/3 & x=5
I got this by using the quadratic formula.
We know that x = 30 + y, because the problem says that there are 30 more football players than basketball players.
Each group has 10 more members added: x + 10 and y + 10. We can write x + 10 as 30 + y + 10 or 40 + y.
The ratio (40 + y)/(y + 10) = 3/2. You can cross multiply to get:
80 + 2y = 3y + 30
Combine like terms to get:
y = 50 members on the basketball team. Since there are 30 more members on the football team, you just add 30 to 50 to get x = 80 members on the football team.
The volume of the new rectangular prism would be 270 cubic centimeters. The reason for this is that when only one dimension is changed, the overall volume is only changed by that same relationship. Because only the height was cut in half, this would be only one of the dimensions.
Answer:
Option C. x = –9, x = –7
Step-by-step explanation:
we know that
In the rational function, the denominator cannot be equal to zero
so
In this problem
we have that the denominator is equal to
equate to zero
so
The solutions is x=-9 and x=-7
so
For x=-7 or x=-9 the denominator is equal to zero
therefore
x=-9, x=-7 are points of discontinuity for the rational function given
