Answer:

-6x⁷ + 12x − 3

Step-by-step explanation:

<u><em>Method 1</em></u> :

-3x^0\ (2x^7-4x+1)

= (-3x^0)\times 2x^7-(-3x^0)\times4x+(-3x^0)\times1

= (-3x^0)\times 2x^7+(3x^0)\times4x+(-3x^0)\times1

=-6x^{0+7}+12x^{0+1}-3x^0

=-6x^{7}+12x^{1}-3x^0

=-6x^{7}+12x-3

<u><em>Method 2</em></u> :

Note : x⁰ = 1

-3x^0\ (2x^7-4x+1)

=-3\ (2x^7-4x+1)

=-3\times2x^7-(-3)\times4x+(-3)\times1

=-6x^7+12x-3

What is the slope of a line that passes through (-4,-13) and (19,11)
inysia [295]
The slope of the line is the gradient, which you can find through rise over run

m (gradient) = (y1 - y2) / (x1 - x2)

where (x1, y1) is the coordinate of the first point, and (x2, x2) is the coordinate of the second point

in your question: 
x1 = -4
x2 = 19
y1 = -13
y2 = 11

m = (-13 -11) / (-4 -19) = -24 / -23 = 24/23 or 1.04 (2d.p.)

hope that helps :)

y=2-3x

y=2-3x,x R

Solving for X

3x+y=2

3x=2-y

x= 2/3-1/3y

x=2/3-1/3y

Find the x-intercept

3x+y=2

3x+0=2

3x=2

x=2/3

Find the y-intercept
