Answer:  The slope of the graph is 3.

Step-by-step explanation:

The equation of a line in slope intercept for is given by :-

y=mx+c, where m is the slope of the line.

The given equation of  the line graphed by Helaine = 12x - 4y = 3

Now, rewrite the above equation in slope-intercept form by adding 4y  and  subtracting 3 from both sides , we get

4y=12x-3

Divide 4 on both sides , we get

y=3x-\dfrac{3}{4} which is the slope-intercept form.

\Rightarrow\text{Slope}=3

Hence, the slope of Helaine's line =3

Answer:

The slope of this line is 3.

Step-by-step explanation:

Solve 12x - 4y = 3 for y to obtain the equation in slope-intercept form:

Add 4y to both sides, obtaining 12x = 3 + 4y

Subtract 3 from both sides:  12x - 3 = 4y

Finally, divide all terms by 4:  y = 3x - 3/4

The slope of this line is 3.

What is 4x(5x-2)=20x-2
Zanzabum

Answer: x = 1.32 and x= 0.076

Step-by-step explanation:

4x(5x-2) = 20x-2

20x^2-8x = 20x-2

20x^2-8x-20x+2=0

20x^2-28x+2=0

Using quadratic equation

x = (-b +or- √(b^2-4ac))/2a

a =20, b=28, c= 2

Substitute into the equation

x= (7+√39)/10. = 1.32

x = (7-√39)/10 = 0.076

-12x+144=-9-63x

-12x+63x=-9-144

51x=-153

x=-153/51=-3

How do you work this out?
Ira Lisetskai [31]
I'm guessing you find the length of the hypotenuse using the pythagorean theorem. 

a² + b² = c²     a and b are the legs and c is the hypotenuse

15² + 8² = c²

225 + 64 = c²

289 = c²

√289 = √c²

17 = c

hope that helps, God bless!
