Write the equation of the line that passes through (2, 3) and is parallel to the line 12x – 5y = 2.
zheka24 [161]
The first thing I'd do is put this equation into standard slope - intercept form. 

12x - 5y = 2               Subtract 12x from each side
-5y = -12x + 2            Divide each side by -5 to isolate the <em>y 
</em><em />y = 12/5(x) - 2/5    
     
 The slope for this equation is 12/5, so we just take that and plug it into the slope - intercept equation with the given points (2, 3)

y = mx + b                    Fill in the variables
3 = 12/5(2) + b             Simplify
3 = 24/5 + b                 Subtract 24/5 (or 4 4/5) from each side
-9/5 = b

Now we just fill in the correct variables (m and b) in the equation to have our final answer. 

y = 12/5x - 9/5

Algebraic expression and identity 1)simplify the following (3a+b)3 +(3a-b)3
mylen [45]

Answer:

(3a+b)^3+(3a-b)^3=54a^3+18ab^2

Step-by-step explanation:

Given: (3a+b)^3+(3a-b)^3

Formula: x^3+y^3=(x+y)(x^2-xy+y^2)

(x+y)^2=x^2+2xy+y^2

(x-y)^2=x^2-2xy+y^2

x\rightarrow 3a+b

y\rightarrow 3a-b

\Rightarrow (3a+b+3a-b)((3a+b)^2-(3a+b)(3a-b)+(3a-b)^2)

\Rightarrow (6a)(9a^2+b^2+6ab-9a^2+b^2+9a^2+b^2-6ab)

\Rightarrow (6a)(9a^2+3b^2)

\Rightarrow 54a^3+18ab^2

Need help immediately
marin [14]

Answer:

Step-by-step explanation:

If A, B, and C are in the ratio of 2:3:5 and they are each getting some amount of money in that ratio, then to find the total amount of money they split is found in Ax + Bx + Cx and we need to solve for x. What we are told is that the smallest share = 210 and obviously A is the smallest share. Therefore,

2x = 210 and x = 105.

The total sum = 210 + 3(105) + 5(105) so

Total sum = 210 + 315 + 525

Total sum = 1050 and

C's share is 525 and

B's share is 315
