3x-1=11 what is the value of x​

Answer:

B. 990<s<1,850

seal dive, s is greater than 990ft and less than 1850 ft

=》 990<s<1850

let x=length

let y=width

x/y=5/2

y=2x/5

area=length*width

area=x*y=x(2x/5)=2x^2/5

2x^2/5=360

2x^2=1800

x^2=900

x=30

y=60/5=12

length= 30 inches

width= 12 inches

there you go!

The dimensions of the rectangle are 20 inches in length and 8 inches in width.

The rectangle has an area of 160 square inches, and the length ratio to the width is 5:2. Let's denote the length as 5x and the width as 2x. The equation for the area of a rectangle is width * length, so we set up and solve the following equations:

Then, we multiply 'x' with the respective parts of the ratio (5 and 2) to find the length and width:

Answer:

(1/2, ∞ ).  This corresponds to Answer B

Step-by-step explanation:

Important:  enclose that negative exponent (-2/3) inside parentheses:

1/3e^(x- 2/3) + 1/2

and also that coefficient, 1/3:

(1/3)e^(x- 2/3) + 1/2

The range of the exponential function y = e^x is (0, ∞ ); that is, y is always positive, never zero or negative.  

The function of that "1/2" is to shift the entire graph 1/2 unit up.

Thus, the range   (0, ∞ )  becomes  (1/2, ∞ ).  This corresponds to Answer B.

Answer:

Answer is B for plato or edmentum

Step-by-step explanation:

The radius of the ring is 1 meter.

Given a ring of fire has a diameter of 2 meters for which a leopard has been trained to jump through.

As we know that in a circle that has a diameter 'd', the radius 'r' is equal to half of the diameter. This means,

[tex]r = \frac{d}{2}[/tex]

Also, the perimeter of this circle is given by

[tex]2\pi r[/tex]

Now,

As given in the question, we have,

The diameter of the ring of fire = 2 meters

So,

The radius of a ring of fire

[tex]= \frac{2}{2}[/tex]

[tex]= 1 meter[/tex]

Hence, the radius of the ring of fire is 1 meter.

The radius of a circle with a diameter of 2 meters is 1 meter. The radius is found by dividing the diameter by two.

The question pertains to determining the radius of a circle when the diameter is given. The ring through which a leopard jumps in the circus has a diameter of 2 meters.

The formula for the diameter of a circle is d = 2r, where d is the diameter and r is the radius of the circle. To find the radius, we simply divide the diameter by 2.

Therefore, the radius of the ring is 1 meter, as r = d / 2 and thus, r = 2 meters / 2.

Step-by-step explanation:

given

x + 4 > - 8 ( subtract 4 from both sides )

x > - 12 ← solution

The step to use is subtract 4 from both sides

The value of x is -12

x + 4 > -8

Subtract 4 from both sides

x + 4 -4 > -8 -4

x > -12

Some factoring lets us write

[tex]a^{2b}-\dfrac1{a^b}=a^{2b}-a^{-b}=a^{-b}(a^{3b}-1)[/tex]

Then

[tex]8a^{3b}=1\implies a^{3b}=\dfrac18[/tex]

[tex]a^{2b}-\dfrac1{a^b}=a^{-b}\left(\dfrac18-1\right)=-\dfrac78a^{-b}=-\dfrac7{8a^b}[/tex]

Taking the cube root to solve for [tex]b[/tex], we find

[tex]\sqrt[3]{a^{3b}}=\sqrt[3]{\dfrac18}\implies a^b=\dfrac12[/tex]

so ultimately

[tex]a^{2b}-\dfrac1{a^b}=-\dfrac7{8\cdot\frac12}=-\dfrac74[/tex]

Answer:

The value of the given expression is    1 - 1 = 0

Step-by-step explanation:

8a^{3b} = 1   can be rewritten as (8a³)^b = 1 = (8a³)^0, which indicates that b = 0.  If b= 0, then 2b = 2(0) = 0.

Then a^(2b) = a^0 = 1, and 1/a^b = 1/1 = 1.

Thus, the value of the given expression is    1 - 1 = 0

A, because just read the three letters in any order but with the origin in the middle

The original area of the garden is 1,000 square feet. When the garden is reduced to 2/5 of its original size, the new area becomes 400 square feet. Therefore, the scale of the new drawing is 2:5.

The original area of the rectangular garden is 100 feet by 10 feet which equals 1,000 square feet. Next season, the garden is decreased to 2/5 of its size. To find the new area of the garden, you multiply the original area by 2/5.

1,000 square feet * 2/5 = 400 square feet.

Therefore, the size of the garden is reduced to 400 square feet which reflects a scale of 2:5 (2 represents the new size, 5 represents the original size) in the new drawing.

The scale of the new drawing after the garden is decreased to 2/5 of its original size is 2/5.

In this problem, we are given the dimensions of a rectangular garden: 100 feet by 10 feet. We need to find the scale of the new drawing after the garden is decreased to 2/5 of its original size.

To find the scale, we can use the proportionality of the areas to the squares of the distances. The original area of the garden is 100 feet * 10 feet = 1000 square feet.

When the garden is decreased to 2/5 of its original size, the new area becomes 1000 square feet * 2/5 = 400 square feet.

In terms of the scale, the new area is 400 square feet, which is 2/5 of the original area. Therefore, the scale is 2/5.

Option B:  g(x) = −5x + 8

Step-by-step explanation:

If we have a function f(x) and wish to make a function g (x) that is equal to the reflection of the function f(x) on the y-axis, then we must make the following transformation to f(x):

[tex]g(x) = f(-x)[/tex]

In this case:

[tex]f(x) = 5x +8[/tex].

So when applying the transformation we obtain:

[tex]g(x) = f(-x) = 5(-x) + 8[/tex]

Step-by-step explanation:

2x-10=2. (Answer=6)

2x=12 (you move the -10 to the other side of the equation to make it positive)

Then you divide by 2

2x divided by 2 equals x 12 divided by 2 is 6

So your number is 6. x=6

And you can check this by redoing the equation but putting 6 instead of x

2(6)-10=2

12-10=2

2=2

This equation is true therefore, your unknown number is 6

Final answer:

The problem is solved by setting up an equation where the larger number (2x) is diminished by 10 equals the smaller number (x) plus 2. Solving for x reveals that the smaller number is 12 and the larger number is therefore 24.

Explanation:

Let's denote the smaller number as x and the larger number as 2x since one number is twice another number. The problem states that if the larger number is diminished by 10, the result, which is 2x - 10, is 2 more than the smaller number. Therefore, we can write the equation:

2x - 10 = x + 2.

To solve for x, we first add 10 to both sides of the equation:

2x = x + 12.

Then, we subtract x from both sides:

x = 12.

Now that we know the smaller number is 12, the larger number is twice that, which means the larger number is 24.

In conclusion, the two numbers in question are 12 and 24.

Answer:

The correct answer is D) f(x) = (x^2 - 2)/3

Step-by-step explanation:

To find an inverse function, swap x and f(x) and then solve for the new f(x). That will be the new inverse function.

f(x) = √3x+2

x = √3f(x)+2

x - 2 = √3f(x)

x^2 - 2 = 3f(x)

(x^2 - 2)/3 = f(x)

Final answer:

To find (f+g)(x) for the given functions f(x)=3x-5 and g(x)=x²+2, you simply add the two functions to get (f+g)(x) = x²+ 3x - 3.

Explanation:

Adding Functions f(x) and g(x)

To find (f+g)(x), you simply need to add the values of f(x) and g(x) together for any value of x. Given that f(x)=3x-5 and g(x)=x²+2, the sum (f+g)(x) is obtained as follows:

Take the expression for f(x) and g(x):

f(x) = 3x - 5

g(x) = x² + 2

Add the two expressions together:

(f+g)(x) = f(x) + g(x)

(f+g)(x) = (3x - 5) + (x² + 2)

Combine like terms:

(f+g)(x) = x² + 3x - 3

The resulting function (f+g)(x) = x² + 3x - 3 is the sum of the two functions f(x) and g(x).

Answer:

Drinks = 6.75

Popcorn= 1

Step-by-step explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25         multiply this equation by 6

12*P + 4D = 39.00

12P + 18D = 133.5          Subtract these two equations

- 14D = - 94.50               Divide by -14

-14D/-14 = -94.5/-14        Do the division

D = 6.75

=========================

12P  +  4D = 39            Substitute for D

12P + 4*6.75 = 39        Combine

12P + 27 = 39               Subtract 27 from both sides

12P + 27-27=39-27      Collect like terms

12P = 12                        Divide by 12

12P/12 = 12/12
