Answer: 10pi
Step-by-step explanation:
C=2*pi*r
C=2*pi*5
C=10*pi (exact)
This is exact if u want numbers, you’ll have to round-off and you can just put 10xpi into a calculator If u want to see.

Answer:
40
Step-by-step explanation:
6% of number = 6/100 × x = 6x/100 = 3x/50
Sum of the number and 6% of itself = 42.4
x + (3x/50) = 42.4
(50x+3x)/50 = 42.4
53x = 42.4 × 50
53x = 2120
x = 2120/53
x = 40
Answer:
y=-2x+b
Step-by-step explanation:
Just use the formula y=ax+b, and input -2 as A, and 3, as x, and 2, as y, and then simplify.
Answer: y+3 = 4( x + 1)
Step-by-step explanation:
The equation in point slope form is given as :
y - 
= m ( x - 
) , where m is the slope
slope = 4
point given : (-1,-3)
Using the formula :
y - = m ( x - )
and substituting the value , we have
y - (-3) = 4 (x -{-1} )
y+3 = 4( x + 1)
