6x-2y=12
Subtract 6x from both sides
-2y=-6x+12
y=3x-6

the answer is $y=3x-6$

subtract 6x on both sides → $-2y=-6x+12$

divide both sides by -2y → $y=3x-6$

PLEASE HELP!!!!

Answer:

Step-by-step explanation:

y_2 - y_1 / x_2 - x _1

4 - 2 / 3 - (-1) = 2/4 = 1/2

y +4 = 1/2 (x + 3) distributive property

y + 4 = 1/2x + 1.5

y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)

therefore your equation is y = 1/2x - 5/2

hope this helps :)

Q4: Write the equation in slope-intercept form of the line that is perpendicular to

forsale [732]

Answer:

5y = x + 11

Step-by-step explanation:

Given parameters:

Equation of the line ;

y = -5x + 1

Coordinates = (2, -1)

Find the equation of a line perpendicular;

Solution:

A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.

Equation of a straight line is expressed as;

y = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

So, the slope of the new line perpendicular is $\frac{1}{5}$ ;

Now let us find the y-intercept of the new line;

x = -1 and y = 2

2 = $\frac{1}{5}$ x (-1) + c

c = 2 + $\frac{1}{5}$ = $\frac{11}{5}$

The equation of the new line is;

y = $\frac{1}{5}$ x + $\frac{11}{5}$

or multiply through by 5;

5y = x + 11

The volume of the cube below is 1/8cm^2 . What is the value of x?

Kipish [7]

We are given

edge of cube =x

we know that formula for volume of cube

$V=x^3$

we are given

$V=\frac{1}{8} cm^3$

we can plug value

$x^3=\frac{1}{8} cm^3$

now, we can solve for x

$\sqrt[3]{x^3} =\sqrt[3]{\frac{1}{8} cm^3 }$

$x=\frac{1}{2} cm$ ............Answer

Math question please show work don't guess

iVinArrow [24]

Let x = the unknown angle

sine of an angle is measure of the opposite leg divided by the hypotenuse.

sin x = 10/21

To now solve for x, we so the inverse of sine.

sin⁻¹(10/21) = x

Plug this into your calculator.

x ≈ 28.44 degrees. This would round down to 28 degrees, option B is your answer.

Can anybody help me out with this it’s due tomorrow please?

pogonyaev

For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
