Answer:
y=x is the correct answer
Explanation:
A linear equation is an equation between two variables that gives a straight line when plotted on a graph.
Why the other ones are incorrect:
y=√x gives a radical function graph
y=x^3 gives a cubic graph
y=x^2 gives a parabola
The 4 in 42,672 is 40,000
And the 4 in 37,426 is 400
The answer is 100
Step-by-step explanation:
21. supplementary angles (add up to 180°)
22. vertical angles (congruent)
23. vertical angles (congruent)
24. supplementary angles (add up to 180°)
25. supplementary angles (add up to 180°)
26. supplementary angles (add up to 180°)
27. supplementary angles (add up to 180°)
