Daud bought a plot of land with an area of 6 2/5 km. He divided the land equally into 8 small plots. What was the total area of

bezimeni [28]

Answer: $\dfrac{12}{5}\ km^2$

Step-by-step explanation:

Given

The area of land is $6\frac{2}{5}\ km^2$

Daud divide the land into 8 equal plots

So, the area of a single small plot is

$\Rightarrow \dfrac{\dfrac{30+2}{5}}{8}\\\\\Rightarrow \dfrac{32}{5\times 8}\\\\\Rightarrow \dfrac{4}{5}\ km^2$

The area of three such plots

$\Rightarrow 3\times \dfrac{4}{5}\\\\\Rightarrow \dfrac{12}{5}\ km^2$

The function f(x)=−3x+2 is defined over the domain −1

DENIUS [597]

Answer:

Yes.

Step-by-step explanation:

$f\left(x\right)=-3x+2$

$f\left(-1\right)=-3(-1)+2$

$y=f(-1)=5$

The domain of this function is all Real numbers $\:\left(-\infty \:,\:\infty \:\right)$

$\{x \in \mathbb{R}: -\infty \:$

How would you solve this?

gulaghasi [49]

Answer:

Step-by-step explanation:

Find the slope = -2/1

Find the y-intercept = 5

Go to graph

put a dot at (0,5)

since it's a negative slope you will go up 2 and left 1

draw your line

_________________________________________________

Find the slope = 3/1

Find the y-intercept = 0

go to graph

Put a dot at (0,0)

Since it is a positive slope you will go down 3 and left 1.

To find the slope and y-intercept use this formula=

y=mx+b

m=slope

b=y-intercept

I'm sorry I don't know how to do a check equation for these.

Help Would Be Greatly Appreciated :)

Answer:

n is $y=\frac{1}{2}x+b$ , p is $y=\frac{1}{2}x-5$ , and r has infinitely many different lines that have this property.

Step-by-step explanation:

If two lines have no solutions, that means that they are parallel. The slopes of two lines are the same if they are parallel. So n's slope is $\frac{1}{2}$ . The y-intercept can be anything except -5, or +b. If two lines have infinitely many solutions, those two lines are exactly the same. So p is just m. If two lines have one and only one solution, that just means the slopes and y-intercepts are different. Since we don't know anything else about line r, we an't model an equation for it.
