Answer:

x= -10

Step-by-step explanation:

(3)8+ [tex]\frac{\sqrt{2x+29} }{3}[/tex]= 9(3) (multiply both sides by 3)

24+ [tex]\sqrt{2x+29}[/tex]= 27  (move the 24 to the right)

[tex]\sqrt{2x+29}[/tex]=27-24 (subtract)

([tex]\sqrt{2x+29}[/tex])²= 3²  (square both sides)

2x+29=9 (move the 29 to the other side)

2x=9-29 (subtract)

2x= -20 (divide both sides by 2)

x= -10

hope this helps and good luck! :)

Step-by-step explanation:

x= y/7 + 2/7

I think thats right

the solutions are (x = 2) and (y = 4).

To find the values of x and y in the given equations, let's solve them step by step:

1. (3^{2x-y} = 1)

For any nonzero number raised to the power of 0, the result is always 1. Therefore, we can rewrite the equation as:

[2x - y = 0]

Now, we have one equation in terms of (x) and (y).

2.[tex]\( \frac{16^x}{4} = 8^{3x-y} \)[/tex]

We'll simplify the left side first:

[tex]\[ \frac{16^x}{4} = \frac{(4^2)^x}{4} = \frac{4^{2x}}{4} = 4^{2x-1} \][/tex]

Now, the equation becomes:

[4^{2x-1} = 8^{3x-y}]

We know that (8 = 2^3), so we can rewrite the right side of the equation in terms of 2:

[4^{2x-1} = (2^3)^{3x-y} = 2^{9x-3y}]

Now, we have:

[4^{2x-1} = 2^{9x-3y}]

Since (4 = 2^2), we can rewrite the left side as:

[ (2^2)^{2x-1} = 2^{4x-2} ]

So, the equation becomes:

[2^{4x-2} = 2^{9x-3y}]

Since the bases are the same, the exponents must be equal:

[4x - 2 = 9x - 3y]

Now, we have two equations:

[2x - y = 0]

[4x - 2 = 9x - 3y]

From the first equation, we can solve for (y):

[y = 2x]

Substituting (y = 2x) into the second equation:

[4x - 2 = 9x - 3(2x)]

[4x - 2 = 9x - 6x]

[4x - 2 = 3x]

[x = 2]

Now, substituting (x = 2) into the first equation to find (y):

[2(2) - y = 0]

[4 - y = 0]

[y = 4]

So, the solutions are (x = 2) and (y = 4).

Answer:

see explanation

Step-by-step explanation:

The exponential function is in the form

y = a [tex](b)^{x}[/tex]

Use points on the graph to find a and b

Using (0, 3), then

3 = a [tex](b)^{0}[/tex] ⇒ a = 3

Using (1, 6), then

6 = 3 [tex](b)^{1}[/tex] ⇒ b = 6 ÷ 3 = 2

The equation is y = 3 [tex](2)^{x}[/tex]

Answer:

y = [tex]3*2^{x}[/tex]

Step-by-step explanation:

The general form for an exponential function is :

y = [tex]ab^{x}[/tex]

We need to find out what a and b are using the values given in the graph.

we can see that (x=0, y = 3) and (x=1, y = 6) are points on the curve. Substitute these into the general equation

for (x=0, y = 3),

3 = [tex]ab^{0}[/tex]

3 = a (1)  or a = 3

for (x=1, y = 6),

6 = [tex]ab^{1}[/tex]

6 = ab (substitute a=3 from previous calculation)

6 = 3b

b = 2

Hence the equation is:

y = [tex]3*2^{x}[/tex]

We have

[tex] \mu = 500[/tex]

[tex] \sigma = 100 [/tex]

425 corresponds to a z of

[tex]z_1 = \dfrac{425 - 500}{100} = -\dfrac 3 4[/tex]

575 corresponds to

[tex]z_2 = \dfrac{575 - 500}{100} = \dfrac 3 4[/tex]

So we want the area of the standard Gaussian between -3/4 and 3/4.  

We look up z in the standard normal table, the one that starts with 0 at z=0 and increases.  That's the integral from 0 to z of the standard Gaussian.

For z=0.75 we get p=0.2734. So the probability, which is the integral from -3/4 to 3/4, is double that, 0.5468.

Answer:

First day: 45x +20y = 875

Second day: 25x + 40y = 775

Adult ticket price: $15

Step-by-step explanation:

See paper attached. (:

The system of equations that model this scenario is:

45x + 20y = $875 equation 1

25x + 40y = $775 equation 2

The price of adults tickets is $15. The price of student's ticket is $10.

In order to determine this value, multiplot equation 1 by 2 and subtract the resulting equation from equation 2.

90x + 40y = 1750 equation 3

975 = 65x

x = 15

Substitute for x in equation 1

45(15) + 20 = 875

675 + 20y = 875

y = (875 - 675) / 20

y = 10

The probability is [tex]0.7727[/tex]   or  [tex]77.27\%[/tex]

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.  

The size of the sample space is the total number of possible outcomes  

The event space is the number of outcomes in the event you are interested in.  

so  

Let

x------> size of the event space

y-----> size of the sample space  

so

[tex]P=\frac{x}{y}[/tex]

In this problem we have

[tex]x=10+7=17[/tex]

[tex]y=10+7+5=22[/tex]

substitute

[tex]P=\frac{17}{22}=0.7727[/tex]

Answer:

Option C is correct.

Step-by-step explanation:

A direct variation function is

y/x = k

i.e. we can say that the ratio of y and x is equal to a constant value k.

We will check for each Option given.

Option A

7/2 = 7/2

8/3 = 8/3

9/4 = 9/4

10/5 = 2

11/6 = 11/6

Option D is incorrect as y/x ≠ k as ratio of y/x for each value of table doesn't equal to constant

Option B

-3/2 = -3/2

-5/4 = -5/4

-6/6 = -1

-7/8 = -7/8

-8/10 = -4/5

Option B is incorrect as y/x ≠ k as ratio of y/x for each value of table doesn't equal to constant

Option C

10/-5 = -2

8/-4 = -2

6/-3 = -2

4/-2 = -2

2/-1 = -2

Option C is correct as y/x = k as ratio of y/x for each value in table c is equal to constant value -2

Option D

-3/-2 = 3/2

-3/1 = -3

-3/0 = 0

-3/1 = -3

-3/2 = -3/2

Option D is incorrect as y/x ≠ k as ratio of y/x for each value of table doesn't equal to constant .

SO, Option C is correct.

Answer: OPTION C

Step-by-step explanation:

The function of direct variation has this form:

[tex]y=kx[/tex]

Where k is the constant of variation.

Let's  check if there is a constant of variation on the Options "a" and "b":

On Option A:

 [tex]\frac{7}{2}=3.5\\\\\frac{8}{2}=4[/tex]

On Option B:

[tex]\frac{-3}{2}=-1.5\\\\\frac{-5}{4}=-1.25[/tex]

There is no constant of variation, then these tables do no represent a direct variation.

On the table shown in Option "d" you can observe that "y" does not change when "x" changes. Then it does not represent a direct variation.

Since on the table shown in Option "c":

[tex]k=-2[/tex]

 This table represents a direct variation.

x=3 and y=2

Step-by-step explanation:

The pythagorean triples are generated by two integrers x and y that can be found by solving the following system of equations:

[tex]\left \{ {{x^{2}-y^{2}=5}\atop {2xy=12}} \atop {x^{2}+y^{2}=13}}\right.[/tex]

Solve the system of equations, and we get that the solution is x=3 and y=2.

Therefore, the combination of integrers that ca be used to generate the pythagorea triple are: x=3 and y=2

Answer:

[tex]x=3[/tex] and [tex]y=2[/tex]

Step-by-step explanation:

The Pythagorean triples can be generated by two values x, y, and a given system of equations:

[tex]x^{2}-y^{2}=5\\2xy=12\\x^{2}+y^{2}=13[/tex]

You can see that each coordinate of the triple is included in each equation.

Remember that Pythagorean triples refers to the values of each side of a right triangle, where is used the Pythagorean Theorem. But, at a higher level, to construct this triples we use the system of equations, with two integers x and y., like this case.

Now we solve the system, the best first step is to just sum the first and third equations, because they have like terms:

[tex]2x^{2}=18\\x^{2}=\frac{18}{2}=9\\x=3[/tex]

Now, we just replace it in the second equation:

[tex]2xy=12\\y=\frac{12}{2x}=\frac{6}{3}=2[/tex]

Therefore the integers that generate the Pythagorean triple [tex](5,12,13)[/tex] are [tex]x=3[/tex] and [tex]y=2[/tex]

The new surface area of a square pyramid when its dimensions are multiplied by 1/3 is calculated by squaring the scale factor (1/3) and multiplying it with the original surface area. In this case, the new surface area is 121 in².

When the dimensions of a square pyramid are multiplied by 1/3, each linear dimension of the pyramid becomes one-third of its original size. Since surface area is a two-dimensional measure (length × width), when you scale down each dimension by a factor of 1/3, the new surface area will be the square of that scale factor times the original area. The surface area is proportional to the square of the scaling factor because area is calculated using two dimensions.

The original surface area is 1,089 in². To find the new surface area, we use the scale factor squared: (1/3) ² = 1/9. We then multiply the original surface area by this factor:

New Surface Area = Original Surface Area × (Scale Factor)²
New Surface Area = 1,089 in² × 1/9
New Surface Area = 1,089 in² / 9
New Surface Area = 121 in²

Therefore, the new surface area of the square pyramid when the dimensions are multiplied by 1/3 will be 121 in².
