Answer:
15 blue marbles
Step-by-step explanation:
Given that:
A bag contains 6 red marbles.
The Ratio of red to blue marbles is 2:5
Thus, the ratio of red marbles for 6 red marbles in a bag will be = 6/2 = 3
Now; the ratio of blue marbles in a bag containing 6 red marbles = 3 × 5 = 15 blue marbles
OR
Mathematically;
![\dfrac{2}{5} \times \dfrac{x}{x} = \dfrac{6}{blue}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Cdfrac%7Bx%7D%7Bx%7D%20%3D%20%5Cdfrac%7B6%7D%7Bblue%7D)
So, we are looking for the same number we can multiply for both the numerator and the denominator that can give us the value of 6 in the above numerator to determine the value of the denominator. If we use 3 since 2× 3 = 6
We have:
![\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{blue}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Cdfrac%7B3%7D%7B3%7D%20%3D%20%5Cdfrac%7B6%7D%7Bblue%7D)
![\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{15}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Cdfrac%7B3%7D%7B3%7D%20%3D%20%5Cdfrac%7B6%7D%7B15%7D)
So, there are 15 blue marbles in the bag.

Step-by-step explanation:
Subtract 12-4
The range is the difference between the lowest and highest numbers.
The equation of function g(x) in terms of f(x) is g(x) = -3[f(x)].
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given:
genera form of an exponential function is y=aeᵇˣ
Now, equation for f(x) is
f(x) = ![e^{(log \;2)x} -2](https://tex.z-dn.net/?f=e%5E%7B%28log%20%5C%3B2%29x%7D%20-2)
Similarly, graph for g(x) is
g(x) = ![-3e^{(log \;2)x} +6](https://tex.z-dn.net/?f=-3e%5E%7B%28log%20%5C%3B2%29x%7D%20%2B6)
Comparing the two function a relation can be establish
g(x) = -3[f(x)]

Answer:
x^2 + y^2 = 100
Step-by-step explanation:
The general form of the equation of a circle is
(x-h)^2+(y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-0)^2+ (y-0)^2 = 10^2
x^2 + y^2 = 100
