Answer:

Infinitely many solutions.

Step-by-step explanation:

2 (n - 1) + 4n = 2 (3n - 1) Let's simplify this to solve it.

2n - 2 + 4n = 6n - 2 Distribute 2(n-1) and 2(3n-1)

2n + 4n - 2 = 6n - 2 Rearrange the left side of the equation.

6n - 2 = 6n - 2 Add 2n + 4n.

-6n        -6n Subtract 6n from both sides.

-2 = -2? Yes, -2 equals -2.

Therefore, the answer is infinitely many solutions, meaning that n can be any real number.

An equation can have no solution, one solution or infinitely many solutions.

The equation [tex]2(n -1) + 4n = 2(3n - 1)[/tex] has infinitely many solutions

Given that:

[tex]2(n -1) + 4n = 2(3n - 1)[/tex]

Open brackets

[tex]2n -2 + 4n = 6n - 2[/tex]

Collect like terms

[tex]2n + 4n - 6n= - 2+2[/tex]

[tex]0 = 0[/tex]

When the solution to an equation is 0 on both sides, the equation has infinitely many solutions

I am going to assume that you mean:

To solve this you must do the opposite of squaring, which would be taking the square root. What you do to one side you must do to the other.

√x² < √49

x < 7

Hope this helped!

~Just a girl in love with Shawn Mendes

Final answer:

To solve the inequality x^2 < 49, we take the square root of both sides resulting in the solution -7 < x < 7, which means x can be any real number between -7 and 7.

Explanation:

The student's question is about solving an inequality involving a square of a variable, specifically x^2 < 49. To solve this inequality, we will first take the square root of both sides, keeping in mind that when we take the square root of a square inequality, we must consider both the positive and negative roots. Therefore, we can express the inequality as -7 < x < 7, since both positive and negative square roots of 49 are 7 and -7, respectively. This represents the range of values for x where the original inequality holds true.

The solution implies that x can take on any real value that is less than 7 and greater than -7. There's no need for tools like completing the square or the quadratic formula here, as the inequality is already in a solvable form.

Answer:

A. A translation right 2 units:

We know that given f(x), the function g(x) = f(x+m), is the same function f(x) but shifted m units to the left. In that sense, a translation right 2 units would be:

g(x) = f(x-2).

B. A translation left 2 units:

We know that given f(x), the function g(x) = f(x+m), is the same function f(x) but shifted m units to the left. In that sense, a translation left 2 units would be:

g(x) = f(x+2).

C. A translation up 2 units:

We know that given f(x), the function g(x) = f(x) + m, is the same function f(x) but shifted m units up. In that sense, a translation up 2 units would be:

g(x) = f(x) + 2

D. A translation down 2 units:

We know that given f(x), the function g(x) = f(x) + m, is the same function f(x) but shifted m units up. In that sense, a translation down 2 units would be:

g(x) = f(x) - 2

Final answer:

The function f(x) translated to g(x) via a translation right 2 units, which shifts the graph of the function 2 units to the right on the x-axis.

Explanation:

The transformation that transformed the parent function, f(x), to g(x) is a translation right 2 units. This is because when the argument of the function f(x) becomes f(x-2), the graph of f(x) is shifted to the right by 2 units along the x-axis. To understand this, let us consider the original function y = f(x).

The graph of the new function y = f(x-2) is the same as the original, but every point on the graph has been moved 2 units to the right. This can also be viewed as if the x-axis (and origin) has shifted 2 units to the left while the graph remains stationary.

She needs to buy 3 spindles of 60 CDS and 2 spindles of 25 CDs.

We know that the possibilities will depend always on how many CDs contain each type of spindles.

There is only one possible combination of spindles that can give the exact amount of CDs needed.

Let's try to find the combinations:

- First combination: With 1 spindle of 60 CDs:

[tex]Spindles_{25}=\frac{TotalCDs-NoOfSpindles_{60}}{25} \\\\Spindles_{25}=\frac{230-60}{25}=\frac{170}{25}=6.8Spindles[/tex]

Since the result is not a whole number, we know that the first combination does not work.

- Second combination: With 2 spindles of 60 CDs:

[tex]Spindles_{25}=\frac{TotalCDs-NoOfSpindles_{60}}{25} \\\\Spindles_{25}=\frac{230-(2)*60}{25}=\frac{110}{25}=4.4Spindles[/tex]

Since the result is not a whole number, we know that the second combination does not work.

- Third combination: With 3 spindles of 60 CDs:

[tex]Spindles_{25}=\frac{TotalCDs-NoOfSpindles_{60}}{25} \\\\Spindles_{25}=\frac{230-(3)*60}{25}=\frac{230-180}=\frac{50}{25}=2Spindles[/tex]

Since the result is a whole number, we know that the third combination works.

Hence, the combination will be:

[tex]TotalCDs=3Spindles_{60}+2Spindles_{25}=3*60+2*25=180+50=230[/tex]

All we have to do is find the volume of the two separate rectangular prisms and add them up.

First we will find the volume of the standing prism:

5in * 3in * 12in = 180in³

Now the other prism:

12in * 4in * 4in = 192in³

Now add them up:

180in³ + 192in³ = 372in³

Answer:

372 [tex]inches^{3}[/tex]

Imagine the figures are each separate. The top figure's dimensions would be L=12 in, W=4 in, and H=4 in. The bottom figure's dimensions would be L=5 in, W=3 in, and H=12 in. So, do the volume formula for each: L x W x H and then add them together.

12 x 4 x 4 = 192 inches^3

5 x 3 x 12 = 180 inches^3

192 + 180 = 372 inches^3

let's recall that the vertical asymptotes for a rational expression occur when the denominator is at 0, so let's zero out this one and check.

[tex]\bf \cfrac{5x+5}{x^2+x-2}\qquad \stackrel{\textit{zeroing out the denominator}~\hfill }{x^2+x-2=0\implies (x+2)(x-1)=0}\implies \stackrel{\textit{vertical asymptotes}}{ \begin{cases} x=-2\\ x=1 \end{cases}}[/tex]

Final answer:

The vertical asymptotes of the function f(x) = (5x+5)/(x² + x - 2) occur where the denominator equals zero. Factoring the denominator, we find the vertical asymptotes to be at x = -2 and x = 1.

Explanation:

The student is asking about the vertical asymptotes of the function f(x) = (5x+5)/(x² + x - 2). To find the vertical asymptotes of a function, we look for values of x where the denominator is equal to zero, because these are the points where the function is undefined and the graph of the function will approach infinity.

To find the vertical asymptotes, set the denominator equal to zero and solve for x:

x² + x - 2 = 0

Factoring the quadratic equation, we get:

(x+2)(x-1) = 0

Therefore, the vertical asymptotes are at x = -2 and x = 1, since these are the values of x for which the denominator becomes zero.

y = - (7/4)x - 1

is with

y = (4/7)x + 9

y = (7/4)x - 2

is with

y = - (4/7)x + 2

Step-by-step explanation:

You can double check by dividing -1 by the number before x. The answer from that calculation will be the number before the x of the perpendicular line's equation

pair with their perpendicular equations are

y = - (6/5)x + 1

y = (6/5)x - 5

y = (4/7)x + 9

y = - (4/7)x + 2

The given line is perpendicular to the required line under the condition of perpendicular lines m1×m2=–1.

As, m1*m2=-1

m1= -1/m2

For first equation

y = (5/6)x - 7

m1= 5/6

So, m2= -1/m2= -6/5

Hence, the equation of perpendicular line is y = - (6/5)x + 1.

Similarly,

y = (5/6)x - 7

m1= 5/6

So, m2= -1/m2= -6/5

Hence, the equation of perpendicular line is y = (6/5)x - 5.

again,

y = - (7/4)x - 1

m1=-7/4

So, m2= -1/m2= 7/4

Hence, the equation of perpendicular line is y = (4/7)x + 9

again,

y = (7/4)x - 2

m1= 7/4

So, m2= -1/m2= -4/7

Hence, the equation of perpendicular line is y = - (4/7)x + 2.

Answer:

The total number of copy rooms in the building is 9.

Step-by-step explanation:

With the given information we can compute the total number of copy rooms (let's call them r) and the boxes of paper Reginald has to distribute among them (already named n).

From the first arrangement we can see that if reginald gives 6 boxes of paper to each room, he will still have 7 boxes. We can write this as:

[tex]n = 6 \cdot r + 7[/tex]

From the second arrangement we can see that if reginald gives 7 boxes of paper to each room, he would still need 2 boxes. We can write this as:

[tex]n = 7 \cdot r - 2[/tex]

From the above, we have a 2x2 system of equations, which can be solved by any method. In this case, we can use equalization to easily find the number of rooms. From the 2 relations we can write:

[tex]6 \cdot r + 7 = 7 \cdot r - 2[/tex]

Puting known and unknowns on opposite sides, we get:

[tex]7+2 = (7-6) \cdot r [/tex]

Solving we get:

[tex]9 = r[/tex]

Therefor the total number of rooms is 9.

Pluging this solution into any of the 2 equations, we can obtain that the number of boxes of paper is 61.

As a reference, the following link is useful:

https://en.wikipedia.org/wiki/System_of_linear_equations

The number of boxes of paper exists at 61.

The whole number of copy rooms as r and the boxes of paper Reginald has to distribute among them (already named [tex]$\mathbf{n}$[/tex] ).

Reginald gives 6 boxes of paper to each room, he will always have 7 boxes. We can write this as:

[tex]$n=6 \cdot r+7$$[/tex]

Reginald shows 7 boxes of paper to each room, he would always require 2 boxes. We can write this as:

[tex]$n=7 \cdot r-2$$[/tex]

From the above equation, we have a [tex]$2 \times 2$[/tex] system of equations, which can be solved in any form. In this issue, we can utilize equalization to easily find the number of rooms.

From the 2 relations we can write:

[tex]$6 \cdot r+7=7 \cdot r-2$[/tex]

Putting known and unknowns on opposite sides, we get:

[tex]$7+2=(7-6) \cdot r$$[/tex]

Solving we get:

[tex]$9=r$$[/tex]

Thus the total number of rooms exists at 9.

Step-by-step explanation:

Quadratic formula: x =√[-b ± v(b² - 4ac)]/2a

Here quadratic equation is  4x2 + 2x – 1

a = 4, b = 2 and c= -1

x =[-b ± √(b² - 4ac)]/2a

 = [-2 ± √(2² - 4*4*-1)]/2*4

 = [-2 ± √(4  + 16)]/8

 = [-2 ± √20)]/8

 = [-2 ± 2√5)]/8
