If possible step by step explanation. thank you!
Answer:
A
Step-by-step explanation:
[tex]\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3[/tex]
[tex](3x^2)^\frac{1}{2} = 3^\frac{1}{2} x[/tex]
Remember that [tex]\frac{x^b}{x^c} =[/tex]x^(b-c)
Using that [tex]\frac{3^\frac{1}{2}x }{3^\frac{1}{2} }[/tex]=3^(1/2x-1/2)=3^((x-1)/2)
[tex]3^\frac{x-1}{2} =3^1[/tex]
So we can say: [tex]\frac{x-1}{2} =1[/tex], because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.

Answer:
1/15
Step-by-step explanation:
I will give brainliest away if you solve this for me please.
Turn both equations into slope-intercept form [ y = mx + b ].
x + 3y = 3
~Subtract x to both sides
3y = 3 - x
~Divide 3 to everything
y = 1 - x/3
~Reorder
y = -1/3x + 1
4x + 3y = -6
~Subtract 4x to both sides
3y = -6 - 4x
~Divide 3 to everything
y = -2 - 4x/3
~Reorder
y = -4/3x - 2
Graph of the equations will be shown below. Note that the solution of graphing two equations will be where both equations intersect. Both lines intersect at (-3, 2), hence making that the solution.

Simplify the expression: 9-2X + 8 + x + 5x
Answer:
4x + 17
Step-by-step explanation:
9 - 2x + 8+ x + 5x
Add/Subtract the values with variables together and the same case for the values without any variables.
5x + x - 2x = 4x
9 + 8 = 17
So you'll end up with the following,
4x + 17

5(2Y - 3) – 4y = 8 – 2y - 15
Justify this please
Answer:
y=1
Step-by-step explanation:
Let's solve your equation step-by-step.
5(2y−3)−4y=8−2y−15
Step 1: Simplify both sides of the equation.
5(2y−3)−4y=8−2y−15
(5)(2y)+(5)(−3)+−4y=8+−2y+−15(Distribute)
10y+−15+−4y=8+−2y+−15
(10y+−4y)+(−15)=(−2y)+(8+−15)(Combine Like Terms)
6y+−15=−2y+−7
6y−15=−2y−7
Step 2: Add 2y to both sides.
6y−15+2y=−2y−7+2y
8y−15=−7
Step 3: Add 15 to both sides.
8y−15+15=−7+15
8y=8
Step 4: Divide both sides by 8.
The value of y is 1
Given the equation 5(2Y - 3) – 4y = 8 – 2y - 15
Expand
10Y - 15– 4y = 8 – 2y - 15
6y - 15 = -7 - 2y
Collect the like terms
6y + 2y = -7 + 15
8y = 8
Divide both sides by 8
8y/8 = 8/8
y = 1
Hence the value y of is 1
