Point slope form is y-y1=m(x-x1)
where the slope is m and a point on the line is (x1,y1)
so
slope bewteen (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
slope bewteen points (-1,-2) and (-2,-6) is
(-6-(-2))/(-2-(-1))=(-6+2)/(-2+1)=-4/-1=4
pick either (-1,-2) or (-2,-6)
I pick (-1,-2)
slpoe is 4
y-(-2)=4(x-(-1))
y+2=4(x+1)
Step-by-step explanation:
height of the cylindrical tank = 20m
circumference of the tank = 39m
volumn of tank =
perimetre formula = 2πrh
= 2 x 3.14 x r x 20 = 39
= 188.4r = 39
r = 188.4/39
r = 4.83
volumn = πr^/2
h
= 3.14 x 4.83^2 x 2 x 20
= 1465.05
volumn of tank = 1465.05
For this case we must algebraically rewrite the given expression. So:
x: It is the variable that represents an unknown number
"double a number" is represented as: 
"6 less than double a number" is represented as: 
So, the final expression is: 
If we want to rewrite the expression in an equivalent way, we take common factor 2:

Asnwer:

Equivalent expression:
