Answer:
<h3>x = -3</h3>
Step-by-step explanation:
First let us get the equation of the coordinates
y-y0 = m(x-x0)
Using the coordinates ( - 3, 2 ), ( - 1, 0 )
m = 0-2/-1-(-3)
m = -2/2
m = -1
Substitute m = -1 and (-1, 0) into the formula
y - 0 = -1(x+1)
y = -x-1
f(x) = -x-1
Since f(x) = 2
2 = -x-1
-x = 2+1
-x = 3
x = -3
Hence the value of x is -3
 
        
             
        
        
        
Answer:
65*h=c
Because if it's per hour c is dependent on the amount of hours.
 
        
             
        
        
        
Answer:
x = 1, y = 10 
Step-by-step explanation:
y = -5x + 15 --- Equation 1 
2x + y = 12 --- Equation 2 
Substitute y = -5x + 15 into Equation 2: 
2x + y = 12
2x - 5x + 15 = 12
Evaluate like terms. 
15 - 3x = 12
Isolate -3x. 
-3x = 12 - 15
Evaluate like terms. 
-3x = -3 
Find x. 
x = -3 ÷ -3
x = 1 
Substitute x = 1 into Equation 2: 
2x + y = 12
2(1) + y = 12
2 + y = 12
Isolate y. 
y = 12 - 2
y = 10 
 
        
                    
             
        
        
        
A)
A polygon is a closed shape so there must be at least three sides. Therefore, the least value that n can be would be three.
