Answer:
x +3 = x^2 +2x -4
Step-by-step explanation:
Straight substitution of the top expression for y gives you ...
x +3 = x^2 +2x -4
__
This lets you rewrite the equation to standard form as ...
x^2 +x -7 = 0
and find the solutions to be ...
x = (-1±√29)/2
Corresponding y-values will be 3 more than this:
y = (5±√29)/2
Step-by-step explanation:
<h2>3(100)2 + 17(100) - 20</h2>
3(10000) + 1700 - 20
30000 + 1700 - 20
31680
Answer:
direct variation
constant = 1/7
Step-by-step explanation:
The equation for direct variation is
y = kx
y = 1/7 x is in this form with the constant of variation being 1/7
M∠YVZ = 90°
The measure of the angle formed by 2 chords that intersect inside the circle is 1/2<span> the sum of the chords' intercepted arcs.
(arcYZ+38)/2 = 90
arcYZ + 38 = 90*2
</span>arcYZ + 38 = 180
arcYZ = 180 - 38
arcYZ = 142°
