Question

Write y = 0.2x - 0.3 in standard form using integers.
Select one:
a. 2x + 10y = -3
b. -2x + 10y = -3
c. -2x - 10y = -3
d. 2x - 10y = -3

Answer 1

what do you get after subtracting 0.2x from both sides? :)

Answer 2

.1 ?

Answer 3

i was lost on this one

Answer 4

eh... i mean from both sides of y=0.2x-0.3

Answer 5

i had D for the answer was that right ?

Answer 6

no :/

Answer 7

solve it step by step, as one of the teachers from my school says:
"Step by step, no regret" :D

Answer 8

dang , can you give me the answer and steps so i can see on the next questions ? Its a prep test HW

Answer 9

ok :)

Answer 10

So we have:\[y=0.2x-0.3\]
Subtracting \(0.2x\) from both sides and we get:\[y-0.2x=0.3\]
Multiplying \(10\) to both sides and we get:\[10y-2x=3\]
Changing the terms on the left hand side and we get:\[-2x+10y=3\]
P.S. \(10y-2x\) is the same as \(+10y-2x\) :D

Answer 11

hope that helps you :D

Answer 12

soorry it's -0.3 and -3 instead of 0.3 and 3

Answer 13

so the answer is b

Answer 14

otayy , thanks

Answer 15

no problem :)
