X1= -20
x2= x2
y1= -15
y2= 12

x1  : x2 ::  y1 : y2
-20 : x   :: -15: 12

Means = x and -15
Extremes= -20 and 12

<span>Product of mean = Product of extremes
</span>       -15x = -20*12
            x = -240/-15
<span>  </span><span>          x2 = 16</span>

Write -3/4x-6 in standard form using integers
taurus [48]

Answer:

3x+4y=-24

Therefore, option C is correct.

Step-by-step explanation:

We have been given the equation:

y=\frac{-3x}{4}-6[/

We will take LCM 4 on right hand side of the above equation:

y=\frac{-3x-24}{4}

Now, we will multiply the 4 in denominator on right hand side to the y in left hand side pof the equation we get:

4y=-3x-24

After rearranging the terms we get:

3x+4y=-24

Therefore, option C is correct.

What is the correct answer in the photo A. B. C. or .D please explain why
balu736 [363]

Answer:

I think its D)

Step-by-step explanation:

7x−3y+2=0

Add -7x to both sides.

7x−3y+2+−7x=0+−7x

−3y+2=−7x

Add -2 to both sides.

−3y+2+−2=−7x+−2

−3y=−7x−2

Divide both sides by -3.

−3y /−3  =  −7x−2 /−3

which equals d)
