Answer: 9
Step-by-step explanation:
Given
The function is 
To make it a perfect square, compare it with 
Here, 

So, c must be square of b i.e. 9

Therefore, value of c is 9.
 
        
             
        
        
        
The problem can be translated into an equation that is something like 4/5 + 3/x = 1/2 
we cannot have x equal to zero because the number can be infinite. 
So the LCD here is 10x, so multiply both sides by that to get: 
8x + 30 = 5x 
Subtract 5x and 30 from both sides: 
3x = -30 
divide: 
x = -10 
The solution isn't zero so there is a solution.
        
             
        
        
        
Answer:
The line passing through (-8, 10) and (-1, 4).
Step-by-step explanation:
Two lines are perpendicular if the product of their slopes is -1. The slope of the line in the picture is  , so we should find a line with slope of
, so we should find a line with slope of  .
.
Note that the slope of the line in the last option is  .
.
 
        
             
        
        
        
Answer:
24, 64
Step-by-step explanation:
If I add 1 to a multiple of 8 I get a multiple of 5, what multiples of 8
meet the condition? (Mention at least 2 of them)
3 x 8 + 1 = 25
8 x 8 + 1 = 65
 
        
             
        
        
        
The equation of any straight line, called a linear equation, can be written as: y= mx+b, where my is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the lone crosses the y axis.
