Answer:
Step-by-step explanation:
<u>Exponential function:</u>
<u>Ordered pairs given:</u>
<u>Substitute x and y values to get below system:</u>
<u>Divide the second equation by the first one and solve for b:</u>
- 80/10 = b³
- b³ = 8
- b = ∛8
- b = 2
<u>Use the first equation and find the value of a:</u>
<u>The function is:</u>
 
        
                    
             
        
        
        
1/5 divided by 5/7 is 7/25
1/5 ÷ 7/5 = 7/25
Your answer is 7/25
        
             
        
        
        
Answer:
Step-by-step explanation:
if solving for y 
solve for y by simplifying both sides of equation, then isolating the variable.
y=-3w+10+W
if solving for W 
W=3w-10+y
if solving for w
w=W/3 - y/3 + 10/3
