Two cell phone plans offer differing text packages. The two plans are outlined below: Plan A: $9.25 per month charge along with a charge of $0.06 per text. Plan B: $2.50per month charge, but a charge of $0.20 per text. Is there a certain number of texts, when the two plans cost the same amount? Determine your answer by setting up a system of equations that model the two plans.

Answer: Y=-2x-5

Step-by-step explanation:

Points: (-4, 3) & (-3, 1)

To find the slope, we use m= (y₂-y₁)/(x₂-x₁)

With these points, m= (1-3)/(-3--4)

This gives us m= -2/1, or -2

Slope-intercept form is y=mx+b

We can plug in the slope now, so y=-2x+b

B is the y-intercept, which is -5, in this case

This gives us y=-2x-5

The number of remaining green and yellow pins is 14 pins and 21 pins.

A proportion is a mathematical calculation that compares two numbers. According to proportion, two sets of given numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.

The fraction of green pins present in the bag is 3/7. Then, the fraction of yellow pins present in the bag is 4/7.

When Yaqub picks up the green pin and gives it to his sister, the new fraction of green and yellow pins are 2/5 and 3/5.

Let x be the number of pins remaining in the bag after 1 pin less. This is written as,

[tex]\begin{aligned}\frac{3}{7}x-1 &= \frac{2}{5}x\\\frac{3}{7}x-\frac{2}{5}x&=1\\x&=35\end{aligned}[/tex]

There are about 35 pins remaining in the bag.

Then, the number of green pins remaining is (2/5) × 35 = 14 pins.

The number of yellow pins remaining is (3/5) × 35 = 21 pins.

the number of fih at 9:00 A.M. (794), which yields 209 fih, the number of fih left at 5:00 P.M. is 585 fih

Subtract the number of fih at 9:00 A.M. (794) from the number of fih left at 5:00 P.M. (209).

794 - 209 = 585

Therefore, the dolphin ate 585 fih.

To estimate how many fih the dolphin ate, we must first subtract the number of fih at 9:00 A.M. (794) from the number of fih left at 5:00 P.M. (209). This gives us 585 fih, which is the estimated number of fih that the dolphin ate. This calculation can be verified by subtracting the number of fih the dolphin ate (585) from the number of fih at 9:00 A.M. (794), which yields 209 fih, the number of fih left at 5:00 P.M.

Answer:

x = 0.5

Step-by-step explanation:

2 (x+1.25) = 3.5

Divide by 2 on both sides.

x + 1.25 = 1.75

Subtract 1.25 on both sides.

x = 0.5

Answer:

x = 0.5

Step-by-step explanation:

2(x+1.25) =3.5

Divide both sides by 2.

x+1.25 = 3.5/2

x + 1.25 = 1.75

Subtract 1.25 from both sides.

What is largest ?

There is a big number—a googolplex—that exists. It consists of 1 and 10100 zeros (googol). A googolduplex, which is an even larger number, is also present. It is 1 and over a googol zeros after that.

Let 'n' be any number, odd or even.

2n will always be even number. This is because, 2n has 2 as common factor. So, 2n is always even.

Eg: 2= 2×1, n=1 ; 4=2×2, n=2 etc

Numbers are even, consecutive.

Consecutive even numbers are 2n-2, 2n, 2n+2,

Eg : For consecutive even numbers, put n=2

2n-2=4-2=2

2n=4

2n+2 =4+2=6,

we get 2,4,6 which are consecutive even nos.

So, numbers are 2n-2, 2n and 2n+2

Their sum= 2n+2+2n+2n-2=6n

Sum=54

6n=54

n=54/6=9

So, n=9

Consecutive numbers are

2n-2= (2×9)-2=16

The area of the square is bigger than the Area of the rectangle.

Suppose the sum of all the sides in a square is this: 4 x A and the same is true of a rectangle, too.

Then, first, the area of the square is A^2.

And next, assuming that we have this: 0 < X < A and that one side in the rectangle is this: (A - X)

we can say that the side next to (A - X) is this: (A + X) because the sum of all the four sides in the rectangle has to be this: (4 x A), which equals the sum of all the sides in the square.

So now, the area of the square is this: A^2, whereas the area of the rectangle is this: (A^2 - X^2), which equals this: (A + X)(A - X).

You know thus now, which of the two areas is bigger, and it’s the area of the square. And the difference between the two areas is this: X^2.

The study revealed that 87% of movie customers spend an average of $6.39 or less on concessions.

To calculate the spending amount that corresponds to the top 87th percentile, we must first calculate the z-score. To do this, subtract the mean of $4.11 from the desired percentile of $6.39, resulting in a difference of $2.28. Next, divide the difference of $2.28 by the standard deviation of $1.37, resulting in a z-score of 1.67. Finally, use a z-score table to find the corresponding percentile of 87%. This means that 87% of movie customers spend an average of $6.39 or less on concessions.

Here by the quantity 1.96σ/√n is often called the margin of error for the estimate.

Then the quantity σ/√n is the standard error, and 1.96 is the number of standard errors from the mean necessary to include 95% of the values in a normal distribution.

A glide reflection or transflection is a symmetry operation in two-dimensional geometry that combines a reflection over a line with a translation along that line into a single operation.

An exchange of points from one side of a line with points on the other side of the mirror at the same distance from the mirror occurs when a mirror line is fixed in the plane. There is a mirror line in every reflection. A mirror reflection is followed by a translation that is parallel to the mirror to create a glide reflection.

Here, the shape is mirrored in the reflection. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

Answer: -25y/216x

Step-by-step explanation: - 25y / 216x

Answer:

(-30x^2/y^2)^5

Step-by-step explanation:

First, we can simplify the exponent in the first term by using the property that (a^m)^n = a^(m⋅n). This property tells us that we can calculate the exponent of the first term by multiplying the exponent of the base by the exponent of the power, which gives us (-3)⋅(-3) = 9. This means that the first term can be rewritten as (2x ⋅ -3/y)^9.

Next, we can simplify the second term by calculating its exponent in the same way, which gives us (-2)⋅(2) = -4. This means that the second term can be rewritten as (-5x/y)^-4.

We can then combine the two terms by using the property that (a^m)⋅(b^n) = (a⋅b)^(m+n). This property tells us that we can calculate the exponent of the combined terms by adding the exponents of the individual terms, which gives us 9 + (-4) = 5. This means that the entire expression can be rewritten as (2x ⋅ -3/y)^9 ⋅ (-5x/y)^-4 = (2x⋅-3/y⋅-5x/y)^5.

Finally, we can simplify the base of the combined terms by multiplying the factors together, which gives us (2x⋅-3/y⋅-5x/y) = -30x^2/y^2. This means that the entire expression can be rewritten as (-30x^2/y^2)^5.
