Answer:
c= 1.74
Step-by-step explanation:
4520 = 3000(c)-700
4520=3000c-700
+700             +700
5220=3000c
c=1.74
to check to see if this is right you would do this:
4520=3000(1.74)-700
4520=5220-700
4520=4520
 
        
             
        
        
        
Answer: 64% of garbage was plastic over there when he was collected garbage.
Step-by-step explanation:
Since we have given that
Total amount of garbage collected by them = 25 pounds
Total amount of garbage which consisted of plastic = 16 pounds
Percent of the garbage was garbage is given by


Hence, 64% of garbage was plastic over there when he was collected garbage.
 
        
                    
             
        
        
        
Answer:  
<u>Step-by-step explanation:</u>
y = 8x² - 3            (Restriction: none -  x is All Real Numbers)
The inverse is when you swap the x's and y's and then solve for y
x = 8y² - 3            <em>swapped the x and y</em>
x + 3 = 8y²           <em>added 3 to both sides</em>
 <em>divided both sides by 8</em>
           <em>divided both sides by 8</em>
 <em>square rooted both sides</em>
           <em>square rooted both sides</em>

<u>Restriction:</u> 
The radical <em>(inside the square root sign)</em> cannot be negative
→  2(x + 3) ≥ 0
       x + 3 ≥ 0         <em>divided both sides by 2</em>
       x       ≥ -3         <em>subtracted 3 from both sides</em>
