Her studies
indicate that there is an inverse relationship between TV time and GPA, and
that a student who watched 15 hours of TV per week can be expected to have a
GPA of 3.5
In equation form
15 = k(1/3.5)
Solve for k
K = 15 * 3.5
<span>K = 52.5 is the constant
of variation</span>
Answer:
6
Step-by-step explanation:
(2.4×10³)×(3×10^x)=7.2×10^9
(3x10^x)=(7.2×10^9)/(2.4×10^3)
3×10^x=3×10^6
10^x=10^6
*when bases are same ,powers are equated*
thus x=6
Y=(-x*x)-4x+3
y=-(x^2+4x-3)
4+y=-(x^2+4x+4)+3
y+4=-(x-2)^2.) +3
-4. -4
y=-((x-2)^2)-1

Answer:
x = 0 and x = -2 are solutions of the given rational equation.
Step-by-step explanation:
We must solve the following rational equation:

Now we present the procedure:
1)
Given
2)
Compatibility with multiplication/Existence of the multiplicative inverse/Definition of division/Modulative property.
3)
Distributive property/
4)
Compatibility with addition/Existence of the additive inverse/Modulative property/Reflexive property
5)
Distributive property/
6)
Result
Now we check the rational equation with each root:
x = 0




x = 0 is a solution of the rational equation.
x = -2



x = -2 is a solution of the rational equation.
