PLEASE HELP!! Find the equation of the line that is perpendicular to y= -2/3x and contains the point (4,-8).
AlladinOne [14]

Answer:

y = 3x/2 +14

Step-by-step explanation:

gradient = -2/3

so if perpendicular,

-2/3 * m2 = -1

m2 = 3/2

if crosses throguh ( -4, 8 )

y - 8 = 3/2 ( x - - 4)

y = 3x/2 + 14

A chemist mixes 4 liters of one acid solution with 10 liters of a 40% solution, resulting in a 30% acid solution. The table show
kondaur [170]

Given that amount of first acid solution = 4 liters

Let concentration of the first acid solution = x

then effective amount of first solution = 4x


Given that amount of second  acid solution = 10 liters

Givn that concentration of the second acid solution = 40% = 0.4

then effective amount of second solution = 0.4(10)


Then amount of resulting acid solution = (4+10) liters

Givn that concentration of the resulting acid solution = 30% = 0.3

then effective amount of resulting solution = 0.3(4+10)


Combining all those results gives equation

4x +0.4(10) = 0.3(4+10)

4x +4 = 0.3(14)

4x +4 = 4.2

4x = 0.2

x=0.05


Hence final answer is 0.05 or you can say 5%.
