Write a rule for the linear function in the graph Plz help

Mathematics
1 answer:
Scilla [17]3 years ago
4 0

Answer:

  y = -x +4

Step-by-step explanation:

The y-intercept of the line is at +4, so the only viable choice is the last choice.

___

Each of the equations is shown in slope-intercept form:

  y = mx + b

where b is the y-intercept, the y-value when x=0. The graph shows that as point (0, 4). So, the equation you're looking for is ...

  y = (some x-term) +4

If you want to spend more brain power on the problem, you can compute the slope of the line as ...

  m = ∆y/∆x = (1-4)/(3-0) = -3/3 = -1

Now, you know for sure the equation of the line is ...

  y = -x +4

one third of a land is on maize, a fifth of the remainder is on potatoes and the rest which is 0.5 ha is on beans. how much of t
disa [49]

Answer: 1250\ m^2

Step-by-step explanation:

Let x= Total land.

Then for Maize = \dfrac{x}{3}    

For Potatoes = \dfrac15(x-\dfrac {x}{3})=\dfrac15(\dfrac{2x}{3})=\dfrac{2}{15}x

For beans = x- (\dfrac{x}{3}+\dfrac{2}{15}x)=0.5 \ ha

\Rightarrow\ x- (\dfrac{5x+2x}{15})=0.5 \ ha\\\\\Rightarrow\ x- (\dfrac{7x}{15})=0.5 \ ha\\\\\Rightarrow\  \dfrac{15x-7x}{15}=0.5 \ ha\\\\\Rightarrow\  \dfrac{8x}{15}=0.5 \ ha\\\\\Rightarrow\  x=0.5\times\dfrac{15}{8} \ ha\\\\\Rightarrow\  x=0.9375 \ ha

1 ha = 10000.00 m²

0.9375 ha = 9375 m²

Land for potatoes = \dfrac{2}{15}(9375) =1250\ m^2

Hence, 1250\ m^2 of the land is on potatoes.
