We can substitute<span> y in the second </span>equation<span> with the first </span>equation<span> since y = y. The solution of the </span>linear<span> system is (1, 6). You can use the </span>substitution method<span> even if both </span>equations<span> of the </span>linear<span> system are in standard form. Just begin by solving one of the </span>equations<span> for one of its variables.</span>
The x-intercept is where the graph crosses the x-axis. that happens when y=0.
x + 2(0) = 5
x = 5
x-intercept is 5
Answer:
s(2) = √7
Step-by-step explanation:
s(2) = √(3[2] + 1) = √7
Probably the intended ellipse is the one with equation

We can parameterize
as a piece of this curve by

with
. Then

etc
