Hello,

2x – 1 = 1 – 2x

<=> 2x-1+2x=1

<=> 4x-1=1

<=> 4x = 1+1=2

<=> x = 2/4 = 1/2

Then there is only one solution.

Thanks

Answer:

one solution, x = 1/2

Step-by-step explanation:

2x -1 = 1 -2x

solve using inverse operations

2x -1 = 1 - 2x

+1        +1

2x = 2 -2x

+ 2x   +2x

4x = 2

/4   /4

x = 1/2

hence this equation has one solution x = 1/2

Answer:

f(9) = 189

Step-by-step explanation:

Plug 9 into x

f(9) = 2(9)^2 + 3(9)

f(9) = 2(81) + 27

f(9) = 162 + 27

Thus, f(9) = 189

Answer:

189

Step-by-step explanation:

f(x) = 2x^2 + 3x , f(9)

f(9) = 2(9)^2 + 3(9)

= 2(81) + 27

= 162 + 27

= 189

Answer:

First, a triangular number can be written as:

Tₙ = (n^2 + n)/2

where n is the number of our triangular number, n = 1 represents the first one, n = 2 represents the second one, etc.

The sum of the first 100 triangular numbers is:

S1 = (T₁ + T₂ + ... + T₉₉ + T₁₀₀)

The sum of the first 99 triangular numbers is:

S2 = (T₁ + T₂ + ... + T₉₉)

Then the difference will be:

D = S1 - S2 = (T₁ + T₂ + ... + T₉₉ + T₁₀₀) - (T₁ + T₂ + ... + T₉₉) = T₁₀₀

And we can find the value of T₁₀₀ if we use the equation for triangular numbers:

T₁₀₀ = (100^2 + 100)/2 = 5,050

Answer:

16 months to grow hair to 8 inches

Answer:

16

Step-by-step explanation:

So we know that one month = [tex]\frac{1}{2}[/tex] inch.

As a result, two months = 1 inch.

Double that.

4 months = 2 inches

8 months = 4 inches.

16 months = 8 inches.

It's always a 2:1 ratio.

Step-by-step explanation:

Volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

For (a):

[tex]Length = 3cm[/tex]

[tex]Width = 4cm[/tex]

[tex]Height = 5cm[/tex]

[tex]Volume = 3cm * 4cm * 5cm[/tex]

[tex]Volume = 60cm^3[/tex]

For (b):

[tex]Length = 3cm[/tex]

[tex]Width = 4cm[/tex]

[tex]Height = 3cm[/tex]

[tex]Volume = 3cm * 4cm * 3cm[/tex]

[tex]Volume = 36cm^3[/tex]

For (c):

[tex]Length = 4cm[/tex]

[tex]Width = 2cm[/tex]

[tex]Height = 2cm[/tex]

[tex]Volume = 4cm * 2cm * 2cm[/tex]

[tex]Volume = 16cm^3[/tex]

For (d):

[tex]Length = 2cm[/tex]

[tex]Width = 3cm[/tex]

[tex]Height = 6cm[/tex]

[tex]Volume = 2cm * 3cm * 6cm[/tex]

[tex]Volume = 36cm^3[/tex]

There's no need to check for (e)

Option b and d answers the question

Using the volume of a rectangular prism to examine the volumes of the prism, the two prisms with a volume of 36cm³ are B and D

Recall :

Prism A :

Volume = 3cm × 5cm × 4cm = 60 cm³

Prism B :

Volume = 3cm × 3cm × 4cm = 36 cm³

Prism C :

Volume = 4cm × 3cm × 2cm = 24 cm³

Prism D :

Volume = 2cm × 6cm × 3cm = 36 cm³

Prism E :

Volume = 4cm × 2cm × 2cm = 16 cm³

Hence, the two rectangular prisms with a volume of 36cm³ are B and D.

Answer: C. Wave X, Wave W, Wave Y, Wave Z.

The option that ranks the time it will take one wavelength to pass a certain point from fastest to slowest is Wave X → Wave W → Wave Y → Wave Z.

The speed at which sound waves will pass through a medium depends on the temperature of that medium.

The higher the temperature of a medium, the faster sound waves will pass through. This is why Wave X will pass through the fastest at 33°C while Wave W will pass through the second fastest at 15°C and so on.

In conclusion, option C is correct.

Step-by-step explanation:

The graph that best shows the relationship between the number of days and the number of frozen treats sold will be a straight line with slope of 120 and will pass through origin. the equation representing the scenerio would be y = 120x

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

Equation : y = Kx also represent constant proportionality.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is the owner of a food cart sells an average of 120 frozen treats per day during the summer.

The given situation represents a direct proportionality between the number of frozen treats sold  vs  the number of days. The graph that best shows this relationship between the number of days and the number of frozen treats sold will be a straight line with slope of 120 and will pass through origin. Mathematically, the equation would be -

y = 120x

Therefore, the graph that best shows the relationship between the number of days and the number of frozen treats sold will be a straight line with slope of 120 and will pass through origin. the equation representing the scenerio would be y = 120x

Answer:

A) 49.4

B) 40

C) 0.00539

D)583.33

Step-by-step explanation:

A)

1 meter/3.25 feet = 15.2 meters/x feet

x feet * 1 meter =  15.2 meters* 3.25 feet

x = 15.2 meters* 3.25 feet/1 feet* meter

x = 49.4

B) 1.6 kilometers/1 mile = x kilometers/25 miles

multiplying both sides by 25 miles

(1.6 kilometers/1 mile )* 25 miles =( x kilometers/25 miles)  * 25 miles

=> 40 kilometers = x kilometers

x = 40

C) 0.926 meter/1 yard = 200 meters/x yards

dividing both sides 200 meters

0.926 meter/(1 yard*200 meters) = 200 meters/(x yards *200 meters)

185.2 /1 yard = 1/ x yards

x yards = 1 yards/185.2

=> x = 0.00539

D) 1 kilometers/0.6 mile = x kilometers/350 miles​

multiplying both sides by 350 miles

(1 kilometers/0.6 mile ) 350 miles= (x kilometers/350 miles​) 350 miles

=> 583.33 kilometers = x kilometers

x = 583.33

Answer:

Step-by-step explanation:

I simplified the expression using the definition of an imaginary number i=√1

First I applied the exponent rule: [tex]a^{bc}=\left(a^b\right)^c[/tex]

[tex]i^{82} = \left(i^2\right)^{41}[/tex]

[tex]=\left(i^2\right)^{41}[/tex]

Then, I applied the maginary number rule: [tex]\:i^2=-1[/tex]

[tex]=\left(-1\right)^{41}[/tex]

Then I used the exponent rule again: [tex]\left(-a\right)^n=-a^n,\:\mathrm{if\:}n\mathrm{\:is\:odd}[/tex]

[tex]\left(-1\right)^{41}=-1^{41}[/tex]

[tex]=-1^{41}[/tex]

Sooo, [tex]1^{41}=1,[/tex] which equals =-1.

Answer:

25/16

Step-by-step explanation:

f(1/4) means that we're plugging in 1/4 for x in the given function.

Our function is:

f(x) = x² + 2x + 1

Plug 1/4 in for x:

f(1/4) = (1/4)² + 2 * (1/4) + 1 = 1/16 + 2/4 + 1 = 1/16 + 8/16 + 16/16 = 25/16

Thus, the answer is 25/16.
