Answer:
y = 6x + 0
Step-by-step explanation:
Equation of a line 
y = mx + c
Given 
( 0 , 0) ( -1/2 , -3)
find the slope m 
m = y2 - y1 / x2 - x1
x1 = 0
y1 = 0
x2 = -1/2
y2 = -3
Insert the values 
m = y2 - y1 / x2 - x1
m = -3 - 0 / -1/2 - 0
 = -3/-1/2
Minus cancels minus 
 = 3/1/2
 = 3/1 ÷ 1/2
 = 3/1 × 2/1
 = 6/1
 = 6
m = 6
Substitute any of the two points given into the equation of a line 
y = mx + c
Where 
y - intercept point y 
x - intercept point x 
m - slope of the line 
c - intercept 
(-1/2 , -3)
x = -1/2
y = -3
-3 = 6(-1/2) + c
-3 = -6/2 + c
-3 = -3 + c
-3 + 3 = c
c = 0
y = 6x + 0
The equation of the line is 
y = 6x + 0

Answer:

Step-by-step explanation:
using the cosine ratio;
 

From the question, the side of the right angle triangle that is adjacent to the measured <a,(i.e BAC) is AC=24 and the hypotenuse is AB=25
This implies that,

 
        
             
        
        
        
Answer:
$149
Step-by-step explanation:
The computation of the amount left for the shopping is shown below;
= Amount have - Electricity bill - Water bill - telephone bill
= $430 - $119  - $65 - $97
= $149
We simply deduct all expenses from the amount available so the remaining amount i.e. left would be considered for shopping 
 
        
             
        
        
        
Answer: x=20
all angles in the triangle are 180 degree, so:
2x+3x+4x=180
9x=180
divide both sides by 9 
x= 20
