5x+8=3x-6 plz help me asap

Ray Of Light [21]

Answer:

x = -7

Step-by-step explanation:

5x+8=3x-6

Subtract 3x from each side

5x-3x+8=3x-3x-6

2x+8 = -6

Subtract 8 from each side

2x+8-8 = -6-8

2x = -14

Divide by 2

2x/2 = -14/2

x = -7

The binomial (2x3 + 3y2)7 is shown in expanded form, but elements of several terms are missing. To complete the expansion, drag

${(2x^{3} + 3x^{2} )}^{7}$
EXPANDED: VERY LONG

$128x^{21} +1344x^{18} y^{2} +6048x^{15} y^{4} +15120x^{12} y^{6} +22680x^{9} y^{8} +20412x^{6} y^{10} +10206x^{3} y^{12} +2187y^{14}$

I used the Binomial Theorem, Which States
$(a + b)(a + b)= {a}^{2} + 2ab + {b}^{2} \\$
$({a}^{2} + 2ab + {b}^{2} )(a + b)={a}^{3} + 3 {a}^{2} b + 3a {b}^{2} + {b}^{3}$
$({a}^{3} + 3 {a}^{2} b + 3a {b}^{2} + {b}^{3}) \times (a + b) = i \: believe \: you \: get \: the \: pattern \: now$

What is the slope-intercept form of 6x −2y−4 = 0?<br> Can you please explain with some details?

Morgarella [4.7K]

$6x -2y-4 = 0 \\ \\the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\6x -2y-4 = 0 \\ \\-2y =-6x+4\ \ /:(-2)\\ \\y=\frac{-6}{-2}x+\frac{4}{(-2)}\\ \\y=3x-2 \\ \\ the \ slope \ (the multiplier \ of \ x \ represented \ by \ m ) \ is \3\\ \\ and \ the \ y-intercept \ (the constantrepresented \ by \ b \ ) \ is \ -2$

8th out of 10 questions

Digiron [165]

The third one since you can interpret the first column of the graph as the x coordinates and the second column as the y coordinate.
