Example:
y = 2x + 1 is a linear equation:
- When x increases, y increases twice as fast, so we need 2x
- When x is 0, y is already 1. So +1 is also needed
- And so: y = 2x + 1
Here are some example values:
x y = 2x + 1
-1 y = 2 × (-1) + 1 = -1
0 y = 2 × 0 + 1 = 1
1 y = 2 × 1 + 1 = 3
2 y = 2 × 2 + 1 = 5
-----------------------------------------------------------------------------
Each solution is a pair of numbers (x,y) that make the equation true. Solving a linear equation usually means finding the value of y for a given value of x. If the equation is already in the form y = mx + b, with x and y variables and m and b rational numbers, then the equation can be solved in algebraic terms.

Answer:
the number of miles run on Thursday is 5.60 miles
Step-by-step explanation:
The computation of the number of miles run on Thursday is shown below
Here we assume the number of miles be x
3 ÷ 4 ÷ 1 = 4.2 ÷ x
3 ÷ 4 ÷ x = 4.2
3x = 16.8
x = 5.6
Hence, the number of miles run on Thursday is 5.60 miles
5.1 = m/0.3
1.53 = m
Hope this helps!
Answer:
198
Step-by-step explanation:
2(9)(11)
Since you know that r = 9 and t = 11, you can substitute the variables to numbers. Then you just multiply to get 198. Hope this helps :)
