Answer:
a. t
b. a (or x = a)
c. r
d. 
1) c
2) t
3) a
4) p
Step-by-step explanation:
a. Draw vertical line passing through the point (c,0). This line intersects the graph at point L. Point L has coordinates (c,t), so

b. If  draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so
 draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so 
c. Note that  then
 then

d. Coordinates of point L are (c,t), coordinates of point K are (a,p)

Answer:6
Step-by-step explanation:
4.8(x)+1.2(y)=2.4
y would equal -6.
4.8(2)+1.2(y)=2.4
9.6 + 1.2y = 2.4      subtract 9.6 from both sides
1.2y = - 7.2    divide by 1.2 on both sides
y = -6
 
        
             
        
        
        
Step-by-step explanation:
 first you have to use the formula for circle is 2πr 
 22
 π= ---- 
 7 
and r stands for radius
