Answer:
x = 3
Step-by-step explanation:
Multiply both sides by 100
2.5 · 100 + 1.5x · 100 = 3.25 · 100 + 1.25x · 100
Refine:
250 + 150x - 250 = 325 + 125x - 250
Simplify:
150x = 125x + 75
Subtract 125x from both sides:
150x - 125x = 125x + 75 - 125x
simplify:
25x = 75
Now all you have to do is Divide both sides by 25:
[tex]\frac{25x}{25}[/tex] = [tex]\frac{75}{25}[/tex]
Now Finally the last part Now just Simplify so therefore the answer is
x = 3

What is the image point of (6, -7) after the transformation D4 T3,5?
The final image of the given points after the given translation and dilation of D4, T3,5 is (27, -23).
What is meant by the term transformation?Image transformations usually involve the modification of various bands of data, such as a single multispectral image either from a number of images acquired at different times of the same area (i.e. multitemporal image data). Image transformations, in either case, generate "new" images from a variety of sources that highlight specific features or characteristics of interest more effectively than the original input images.For the given image point of (6, -7) .
First there is a dilation of 4.
Thus,
Image = (6×4 , -7×4)
Image = (24, -28)
Now, there is translation of 3 units right on x axis and 5 unit upward on y axis; T3,5.

Which region has a population density less than 60 animals per square mile
Explanation
We will have to find the population density of each of the regions
To get the population density, we will have to divide the population of each region and then divide by the area of the of each region
For part A
[tex]Area=\frac{1}{2}\times40\times35=700mi^2[/tex]The population density of region A is
[tex]\frac{42500}{700}=60.71\text{ animals per square miles}[/tex]For region B
The area of region B is
[tex]\frac{1}{2}\times50\times38=950mi^2[/tex]The population density of region B is
[tex]\frac{60800}{950}=64\text{ animals per square miles}[/tex]For region C
[tex]area=\frac{1}{2}\times42\times49=1029mi^2[/tex]The population density of region C
[tex]\frac{57300}{1029}=55\text{ animals per square mile}[/tex]Thus, we can observe that Region C has a population density lower than 60 animals per square miles

The solution of the inequality negative 3 e greater than 21 is e less than negative 7.
Inequality:
If the two real numbers or algebraic expressions are related using the symbols >, <, ≥, ≤, then the expression is called an inequality.
Given,
Here we have the statement for the inequality.
"negative 3 e greater than 21".
Now, we have o solve it and then we have to find the value of e.
The given statement is rewritten as the following expression form,
That is,
-3e > 21
Here we need the value of e, so we have to divide both sides by 3, then we get,
=> -e > 7
To remove the negative sign, we have to reverse the inequality, then we get the value of e as
=> e < -7
Therefore, in statement it can be written as "e less than negative 7".

Sandra will be paid 72.30 dollars for babysitting for 12 hours.
Explanation
We are told that Sandra earned 60.25 dollars babysitting 10 hours.
If she babysits at the same rate, we are asked to calculate the amount she would earn if she babysits for 12 hours.
Let the amount Sandra is paid for babysitting for 12 hours be x dollars
10 hours = 60.25 dollars
12 hours = x dollars
We can write a mathematical relationship by cross multiplying
10 × x = 12 × 60.25
10x = 723
Divide both sides by 10
(10x/10) = (723/10)
x = 72.3 dollars

Which is the domain and range of the parabola with the equation… Thanks
Okay, here we have this:
Considering the provided equation of the parabola, we are going to find the requested domain and range, so we obtain the following:
Domain: Corresponds to all the values that x can take in the function. Given that in this case no value of x indeterminates the function, and that x can take any value, then its domain will be: (-∞, ∞).
Range: Corresponds to all the values that the dependent variable can take. In this case, since it is a parabola of the form ax^2+bx+c, and that a is less than or greater than 0, its range will be all values greater than or equal to its y-coordinate of the vertex, which for this case is (5, -15). So its range is: [-15, ∞).
Therefore finally we obtain that the correct answer is the fourth option.

When we have a radical, we can simplify it by the rule:

The function f(x) is represented in the graph. The function g(x) is represented by the data in the table. We have to find the correct comparison between the two functions.
The comparison is to be done on the basis of the lengths of the x-intercept and y-intercept and the end behaviour of both functions. From the given values, we conclude that the x-intercepts for both functions are the same, but the y-intercepts are different.
