Step-by-step explanation:
26=r+10
subtract 10 from both sides
26-10=16. 10-10=0
16=r
Had trouble reading your post. It's important that you separate each equation with plenty of spaces, or, b etter yet, type only one equation per line:
<span>x-y=19 -2x+y/6=28 should be:
</span><span> x-y=19
-2x+y/6=28
Does (-31,-56) satisfy this system? Is (-31) - (-52) = 19? No. Move on to the next system and check again whether or not (-31, -56) is a solution.</span>
Answer:
Step-by-step explanation:
Given the equation
A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.
is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.
so
Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.
Therefore,
Please check the attached figure too.
