(| 5 - 3x | - 1) - (1 - 3x) = 0

|5 - 3x| - 1 - 1 + 3x = 0

|5 - 3x| - 2 + 3x = 0

1) (5 - 3x) - 2 + 3x = 0, if 5 - 3x >= 0

3 = 0. has no solutions

2) -(5 - 3x) - 2 + 3x = 0, if 5 - 3x < 0

-5 + 3x - 2 + 3x = 0

6x = 7

x = 7/6

5 - 3x < 0

-3x < -5

x > 5/3.

has no solutions

Answer:

3*2= $\sf{\pink{\dfrac{4}{5}}}$

Step-by-step explanation:

Given that,

x*y= $\dfrac{(2x-y)}{(x+y}$

3*2=

$\dfrac{2(3)-2}{3+2}\\\\\dfrac{6-2}{5}\\\\\dfrac{4}{5}$

Therefore:-

$\therefore {3*2}=\dfrac{4}{5}$

(6,3*10^-2)÷(2,1*10^4

nexus9112 [7]

Answer:

$3*10^{-6}$ or $0.000003$

Given expression:

$(6.3*10^{-2}) : (2.1*10^4)$

Simplify it in steps below:

$(6.3*10^{-2}) : (2.1*10^4) =$
$(6.3 :2.1)*(10^{-2}:10^4)=$
$3*(10^{-2-4})=$
$3*10^{-6}$ or $0.000003$

Used properties:

$\cfrac{ab}{cd}=\cfrac{a}{c}*\cfrac{b}{d}$

$a^b:a^c=a^{b-c}$

$a^{-b}=1/a^b$

M: -1/2 Point: (-1, 3) Solve for y=mx+b Help

ohaa [14]

Answer:

y= (-1/2)x+(5/2)

Step-by-step explanation:

equation point slope

(y-y1)=m(x-x1)

y-3 = -1/2(x+1) add -3 to both sides and distribute

y=( -x/2) +(-1/2)+3 rewrite 3 as 6/2

y=(-1/2)x +(-1+6/2) solve

y= (-1/2)x+(5/2)

Brainly do ur magic pls.?

jok3333 [9.3K]

1. 3y

multiplying 3 and y together gets 3y

2. y-5

5 less implies that we subtract 5 from y

3. y+7

adding 7 to y, self-explanatory

4. 9y

same thing as #1

5. $\frac{y}{8}$

quotient of implies division, since number y is listed first, y is the numerator

8x+3y=18

Minchanka [31]

Step-by-step explanation:

8x+3y=18

subject y according y=mx+c

y=8/3x-6

(-9,-13)

substitute -9 to y=8/3x-6

-13=8/3×(-9)+c

11=c

y=8/3x+11
