Answer:Jason’s salary depends on the number of hours he works. The independent variable is the number of hours and the dependent variable is salary. Let x = the number of hours worked Let y = Jason’s salary The set of ordered pairs {(1, 10), (2, 20), (3, 30), (4, 40), (5, 50)} can be used to represent the function, assuming Jason earns $10 per hour The number of hours the train takes depends on the distance. The distance is independent and the number of hours is dependent. {(2,20)(4,40)(6,60)(8,80)(10,100)} For every 2 hours it takes 20 miles. The amount of money depends on the time worked.
Step-by-step explanation:
We are given wit the scaling factor of
1 inch : 0.51 mile
The distance between the two buildings in real life is 2.3 miles. On the map they are
2.3 miles (1 inch / 0.51 mile) = 4.5
inches apart<span />
Okay so in this question it says to solve f(7). This means to plug in the 7 every where you see an x, so that it looks like this: 
Then you'll solve it like a normal equation.
Hope this helped! Let me know if there is anything I need to clarify or explain more in depth!
Answer:
Step-by-step explanation:
I feature of congruence of triangles: side-side-side
Available two triangles must match equal sides, these triangles are congruent.
II feature of congruence of triangles side - angle - side
Available two sides and the angle contained between them in one triangle are equal to two sides and the angle contained between them in the other triangle, these triangles are congruent.
III feature of congruence of triangles angle - side - angle
If the side and two adjacent angles in one triangle, they are equal to the side and two adjacent angles of the other triangle, these triangles are congruent.
