Answer:
y= -3/5x - 7 (assuming slope-intercept form)
Step-by-step explanation:
First, we see the slope. The basic template for a slope-intercept question is 
y=mx + b
So, we put in -3/5 as "m" in this case, as it is the slope to get y= -3/5x +b
To find b, we can just try out the point that the equation gave us. 
-3/5 * -5 = 3 
Then, to get to -4 from 3, we need to subtract 7. 
Then, we get our whole slope-intercept equation. y=-3/5x - 7
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation: 60 ÷ 0.25 = 240

Answer:
Infinitely many solutions. Each real number is a solution of this equation.
Step-by-step explanation:
-5 + (-5r) + 10 = -5r + 5
5 - 5r = -5r + 5       <em>add 5r to both sides</em>
5 = 5   TRUE
 
        
                    
             
        
        
        
The volume of a box with dimensions x by x by x is  

.
So if we are given the volume V of a cube-shaped box, the side length of thit is 
![\sqrt[3]{V}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7BV%7D%20)
.
So we calculate the cubic roots of the volumes we have, and we add their heights.
To calculate the cubic root of 729, we can factorize it, and group the perfect cubes together, as follows:


, which we recognize as 

so 

similarly 1,331 can be found to be 

.
Thus we have 2 boxes with side length equal to 11 m and one with side length equal to 9 m.
Answer: h= 11+11+9 = 31 (meters)
 
        
        
        
Answer:
The answer is 6.79 dollars
Step-by-step explanation:
The answer is 6.79 dollars because 5 times 1 (she bought 5 eggs for 1 dollar each) + the added basket 1.79 equals $6.79
