The line 3x-8y=k cuts the x-axis and y- axis at the point A and B respectively. If the area of ∆AOB =12sq.units, find the value
Sladkaya [172]

Given:

The equation is:

3x-8y=k

It cuts the x-axis and y- axis at the point A and B respectively.

The area of ∆AOB =12 sq.units.

To find:

The value of <em>k</em>.

Solution:

We have,

3x-8y=k

Substituting x=0 to find the y-intercept.

3(0)-8y=k

0-8y=k

y=\dfrac{k}{-8}

y=-\dfrac{k}{8}

Substituting y=0 to find the x-intercept.

3x-8(0)=k

3x-0=k

x=\dfrac{k}{3}

Area of a triangle is:

A=\dfrac{1}{2}\times base\times height

The height of the ∆AOB is OB=\dfrac{k}{8} because distance cannot be negative and the base of the ∆AOB is OA=\dfrac{k}{3}. So, the area of the ∆AOB is:

A=\dfrac{1}{2}\times \dfrac{k}{8}\times \dfrac{k}{3}

A=\dfrac{k^2}{48}

It is given that, the area of ∆AOB = 12 sq.units.

\dfrac{k^2}{48}=12

k^2=576

k=\pm \sqrt{576}

k=\pm 24

Therefore, the value of k is either 24 or -24.

Simplify-3/7(y-28)-1/21y
Stells [14]

Answer:

Step-by-step explanation:

I will assume that you meant:  (-3/7)(y-28) - (1/21)y

Using the distributive property of multiplication, we get:

(-3/7)y + (3/7)(28) - (1/21)y

Let's first reudce the middle term.  We get:  12

Then we have:

(-3/7)y + 12 - (1/21)y

Here there are two different denominators.  We must combine the y terms.  The LCD here is 21.  Multiplying (-3/7)y by 21/21, we get the equivalent:

-9y

------ + 12 - (1/21)y

 21

or:

-9y          21

------ + 12----- - (1/21)y

 21           21

Combining the y terms, we get (-10/21)y:

-10y      252

------- + -------- = (1/21)(-10y + 252)

 21          21

Help please!!!!!!!!

The slope can be found using rise over run
the line goes up 5 and over 10
so the slope would be 5/10 or 1/2

therefore the equation of the line is:
y=1/2x
