A farmer owns 1,000 acres. The farmer buys farms of 120 acres, 160 acres, and 700 acres and sells one farm of 190 acres. How man

vredina [299]

Answer : The area of land a farmer own now is, 1790 acres

Step-by-step explanation :

Area of land a farmer owns = 1000 acres

Total area of land farmer buy = 120 acres + 160 acres + 700 acres

Total area of land farmer buy = 980 acres

Area of land a farmer sells = 190 acres

Thus, the remaining area of land a farmer has = Total area of land farmer buy - Area of land a farmer sells

The remaining area of land a farmer has = 980 acres - 190 acres

The remaining area of land a farmer has = 790 acres

Now we have to determine the area of land a farmer own now.

Area of land a farmer own now = 1000 acres + 790 acres

Area of land a farmer own now = 1790 acres

Therefore, the area of land a farmer own now is, 1790 acres

Find the value of y so that the line passing through the two points have the given slope (2,3) (7,y) m=-2/5

Liono4ka [1.6K]

Answer:

y = 1

Step-by-step explanation:

Find the slope of the line passing through the points $(2,3)$ and $(7,y):$

$m=\dfrac{y-3}{7-2}=\dfrac{y-3}{5}$

The slope of the line is equal to

$m=-\dfrac{2}{5},$

then

$\dfrac{y-3}{5}=-\dfrac{2}{5}\\ \\y-3=-2\\ \\y=-2+3\\ \\y=1$
