Solve -2x+3=-3x+2 and is it no solution <br>One solution or infinitely many solutions. ​
Alex73 [517]

Answer is =-1

implifying

-2x + 3 = -3x + 2

Reorder the terms:

3 + -2x = -3x + 2

Reorder the terms:

3 + -2x = 2 + -3x

Solving

3 + -2x = 2 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

3 + -2x + 3x = 2 + -3x + 3x

Combine like terms: -2x + 3x = 1x

3 + 1x = 2 + -3x + 3x

Combine like terms: -3x + 3x = 0

3 + 1x = 2 + 0

3 + 1x = 2

Add '-3' to each side of the equation.

3 + -3 + 1x = 2 + -3

Combine like terms: 3 + -3 = 0

0 + 1x = 2 + -3

1x = 2 + -3

Combine like terms: 2 + -3 = -1

1x = -1

Divide each side by '1'.

x = -1

Simplifying

x = -1

The weekly earnings of students in one age group are normally distributed with a standard deviation of 47 dollars. A researcher
ELEN [110]

Answer:

Option D) 340

Step-by-step explanation:

We are given the following in the question:

Alpha, α = 0.05

Population standard deviation, σ = $47

Margin of error = 5

95% Confidence Interval:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

\text{Margin of error} = z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

5 = 1.96(\dfrac{47}{\sqrt{n}} )\\\\\sqrt{n} = \dfrac{47\times 1.96}{5}\\\\n = 339.443776\\\Rightarrow n \approx 340

Thus, the correct answer is

Option D) 340

The formula for the area of a rhombus is A = a equals StartFraction one-half EndFraction d 1 d 2.D1d2, where d1 and d2 are the l
Gelneren [198K]

Answer:

d1=2A/d2

d2=2A/d1

Step-by-step explanation:

The options of this question are:

1. d₁=2Ad₂

2. d₁= 2A/d₂

3. d₂= d₁/2A

4. d₁= 2A/d₂

5. d₂= 2Ad₁

Given:

A=1/2(d1*d2)

Multiply both sides by 2

We have,

2A=d1*d2

Divide both sides by d2

2A/d2=d1*d2/d2

2A/d2=d1

Therefore, d1=2A/d2

Similarly, from the previous equation

2A=d1*d2

Divide both sides by d1

2A/d1=d1*d2/d1

2A/d1=d2

Therefore,

d2=2A/d1

Options

2. d₁= 2A/d₂

4. d₁= 2A/d₂
