Answer:
4.5 g 56.25 g Since the only type of measurement mentioned in this question is weight or mass, I'll assume that the percentage concentration is % m/m (mass/mass). For that type of concentration measurement, simply multiple the percentage by the total mass to get the mass of the desired substance. So 150 g * 3% = 150 g * 0.03 = 4.5g For the amount of 8% solution with the same amount of dry substance, there's 2 ways of calculating the mass of solution. First, use the ratio of percentages, multiplied by the mass of the original solution to get the desired amount of new solution: 3/8 * 150 g = 56.35 g Or calculate it from scratch, like 4.5/X = 8/100 450/X = 8 450 = 8X 56.25 = X In both cases, the result is that you desire 56.25 grams of 8% solution.
 
        
             
        
        
        
Answer:
A) 
B) 
C) 
Step-by-step explanation:
So we have the equation: 

Let's write this in function notation. Thus: 

A)
To flip a function over the x-axis, multiply the function by -1. Thus: 

Simplify: 

B) To flip a function over the y-axis, change the variable x to -x. Thus: 

Simplify: 

C) A reflection over the line y=x is synonymous with finding the inverse of the function. 
To find the inverse, switch x and f(x) and solve for f(x): 

Switch: 

Subtract 4 from both sides: 

Divide both sides by 5: 

And we're done :)
 
        
             
        
        
        
Answer:from my understanding it should be D I would wait for someone else to answer just in case I’m wrong.
