5.49 $, just add them altogether
Y=2x + 5, the Y-intercept is 5
Answer:
The best first step for solving the given system using substitution is substitute the value of -9x from equation 1 in equation 2
Step-by-step explanation:
Given :
To Find: What is the best first step for solving the given system using substitution?
Solution:
--1
--2
Since we are supposed to solve these equations using substitution method
So, the first best step for solving the equation is :
Both the equations contains -9x
So, substitute the value of -9x from equation 1 in equation 2
Substitute the value of y in 1 to get value of x
So,
Thus the solution is (2,7)
Hence the best first step for solving the given system using substitution is substitute the value of -9x from equation 1 in equation 2
Answer: Choice C
We have an x axis reflection
The x coordinate stays the same while the y coordinate flips from positive to negative, or vice versa.
For example, point L is located at (-4,2) and it moves to L ' (-4, -2). The other points follow this same pattern.
