Answer:

D. x = 7

Step-by-step explanation:

NOTE : there should be an equal sign somewhere in the given expression.

suppose the equation is the following:

3(x-4)-5 = x-3

………………………………………………………

3(x - 4) - 5 = x - 3

⇔ 3x - 12 - 5 = x - 3

⇔ 3x - 17 = x - 3

⇔ 3x - 17 + 17= x - 3 + 17

⇔ 3x = x + 14

⇔ 2x = 14

⇔ x = 14/2

⇔ x = 7

write the equation of the line that is parallel to the line y=-5/3x-2 and goes throught the point (-3,1)

max2010maxim [7]

Answer:

y = (-5/3)x - 4

Explanation:

The equation of a line with slope m that goes through the point (x1, y1) is:

$y-y_1=m(x-x_1)_{}$

Additionally, two lines are parallel if they have the same slope.

The slope of the line y = (-5/3)x - 2 is (-5/3) because it is the number beside x.

So, the slope of our line is also -5/3.

Therefore, replacing m by -5/3 and (x1, y1) by (-3, 1), we get that the equation of the line is:

$\begin{gathered} y-1=-\frac{5}{3}(x-(-3)) \\ y-1=-\frac{5}{3}(x+3) \end{gathered}$

Finally, solving for y, we get:

$\begin{gathered} y-1=-\frac{5}{3}x-(\frac{5}{3}\cdot3) \\ y-1=-\frac{5}{3}x-5 \\ y=-\frac{5}{3}x-5+1 \\ y=-\frac{5}{3}x-4 \end{gathered}$

So, the answer is:

y = (-5/3)x - 4

Solve v pls 3|v - 3|=9

Ganezh [65]

The answer is 0

Let's solve your equation step-by-step.

3(|v−3|)=9

Step 1: Divide both sides by 3.

3(|v−3|)3=93

|v−3|=3

Step 2: Solve Absolute Value.

|v−3|=3

We know either v−3=3orv−3=−3

v−3=3(Possibility 1)

v−3+3=3+3(Add 3 to both sides)

v=6

v−3=−3(Possibility 2)

v−3+3=−3+3(Add 3 to both sides)

v=0

Answer:

v=6 or v=0
