Solve 2^(x-1) =11 change of base

Step-by-step explanation:

We have the following equation

To solve the function, apply the equation on both sides of the equation

Remember that

So

Finally

x = 4.46

Step-by-step explanation:

We are to solve the following expression:

Taking the natural logarithm of both sides of the equation to remove the variable from the exponent. to get:

Applying the distributive property:

Solving for x to get:

x = 4.46

is should be y = 5x

step-by-step explanation:

correct me if im wrong

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
