Which expression is equivalent to -2/5(x + 0.8) + 1/50

-0.4x - 0.30  or  

Step-by-step explanation:

Change all the fractions to decimals.

-2/5 = -0.4  Distribute that over x and 0.8   1/50 =  0.02

you get -0.4x -0.32 + 0.02

Change all the decimals to fractions.

0.8 is 8/10  so  -2/5 times 8/10  is -16/50

-2x/5  - 16/50 + 1/50   add or subtract the fractions to get -15/50 Then reduce (÷5)

-2x/5 - 3/10

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
