Question

step by step x- and y-intercept of the following problem?
-5x+3y=-24

Answer 1

To get x-intercept put y=0 in the equation
to get y-intercept put x=0 in the equation

Answer 2

i need someone to help me step by step i dont understand @hartnn

Answer 3

-5x+3y=-24
if you put y= 0 in this, what do u get ?

Answer 4

-5x+3(0) = -24

Answer 5

so basically -5x=-24 because 3(0) is 0 @hartnn

Answer 6

YES

Answer 7

just divide both sides by -5 now

Answer 8

so the answer would be x=-24/-5 which is 4.8 @hartnn

Answer 9

x = 24/5 = 4.8
yes, correct :)

Answer 10

thank you very much medal was rewarded and fanned ;) @hartnn

Answer 11

thanks for the testimony! :D

y-intercept is remaining....or did u already found out ?

Answer 12

i actually already found it but can you check it for me?
my final answer was y=-8 @hartnn

Answer 13

\(\huge \checkmark \\ \huge \ddot \smile \)

Answer 14

thanks!! greatly appreciated...
can you help me with another word problem?
@hartnn

Answer 15

sure :)

Answer 16

okay here it is:
"In 2005 a Caribbean nation produced 0.7 million tons of cane sugar. Annual production was projected to decrease by 0.5 million tons each year for the next 5 years. write a linear function that models this situation."

Answer 17

@hartnn

Answer 18

so, in 2005, its 0.7
in 2006, 1 year later , its 0.2
in 2007, 2 years later, its -0.3
and so on...

Answer 19

yes so the linear function would be written as f(x)....

Answer 20

i am wondering how will they produce negative quantity of sugarcane :P

Answer 21

lol maybe the company stops producing when they are negative lol

Answer 22

do u have choices for this ?

Answer 23

because the answer really depends on what u take for x

Answer 24

no..just this word problem nothing else

Answer 25

they are asking for a linear function to model the situation does that mean solve for x?

Answer 26

ok ,
so i will take 'x' as number of years after 2005
so we have
x= 0, y = 0.7
x=1, y = 0.2
x=2 , y = -0.3
and so on

a linear function is of the form
y = f(x) = mx+c

Answer 27

where, m= slope
and c = y-intercept

Answer 28

when x =0
y = 0.7
so,
0.7 = 0+c
that is c= 0.7

when x= 1, y= 0.2
0.2 = m +0.7
m = -0.5
so your linear function is
y= -0.5 x + 0.7
