The entire range of independent variable values is the domain of a function.
After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).
What is domain and range?
- The collection of all x-values that can cause the function to "work" and produce actual y-values is known as the domain.
- The range is the set of y-values that are produced when all the conceivable x-values are substituted.
The entire range of independent variable values is the domain of a function.
Keep these things in mind when locating the domain:
- A fraction's denominator (bottom) cannot be 0.
- In this section, the integer following a square root symbol must be positive.
After substituting the domain, the range of just a function is the entire set of all possible values for the dependent variable (often y).
The variety of potential y-values makes up a function's range (minimum y-value to maximum y-value)
- To observe what happens, substitute several x-values into the expression for y.
- Be sure to search for the least and highest y values.

Answer:
50
Step-by-step explanation:
![7x = (90 + 5x) \times \frac{1}{2}](https://tex.z-dn.net/?f=7x%20%3D%20%2890%20%2B%205x%29%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B2%7D%20)
![7x = {2.5x} + 45](https://tex.z-dn.net/?f=7x%20%3D%20%20%20%7B2.5x%7D%20%2B%2045)
![4.5x = 45](https://tex.z-dn.net/?f=4.5x%20%3D%2045)
![x = 10](https://tex.z-dn.net/?f=x%20%3D%2010)
Plug 10 in for x.
![5(10) = 50](https://tex.z-dn.net/?f=5%2810%29%20%3D%2050)
Answer:
![\mathsf {x = 76}](https://tex.z-dn.net/?f=%5Cmathsf%20%7Bx%20%3D%2076%7D)
Step-by-step explanation:
The given pair of angles lie on a line, hence they are classified as linear angles. They possess the property by which their sum is equal to 180°.
![\textsf {Solving :}](https://tex.z-dn.net/?f=%5Ctextsf%20%7BSolving%20%3A%7D)
![\implies \mathsf {x + 17 + 87 = 180}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cmathsf%20%7Bx%20%2B%2017%20%2B%2087%20%3D%20180%7D)

Answer: Carlos is right
Step-by-step explanation:
why because in dilation, the image and the original are similar, in that they are the same shape but not necessarily the same size. They are not congruent because that requires them to be the same shape and the same size, which they are not (unless the scale factor happens to be 1.0).
Diya is wrong because the picture is the not the same size && the image is going to stay the same
(4 feet wide), 12 feet in length. 4*3=12 4*12=48
