Hi!
-32 = 4b
4b = -32
b = -32 : 4
<u>b </u><u>=</u><u> </u><u>-</u><u>8</u>
2c is a factor of both terms.
.. area = 2c(c+1)
Possible expressions for length and width are
1, 2, c, 2c, c+1, 2(c+1), c(c+1), 2c(c+1).
Vertices (3,0),(-3,0) co-vertices (0,-5),(0,5)
transverse axis (line passing vertices) is on(or parallel to) x-axis then formula is
(x-h)^2/a^2 - (y-k)^2/b^2 = 1
..notice.. x^2 is on positive / y^2 is on negative
center (h,k) is midway between vertices = (0,0)
we have h = k = 0 and now formula is
x^2/a^2 - y^2/b^2 = 1
a is the distance from a vertex to center = 3
b is the distance from a co-vertex to center = 5
the formula is
x^2/3^2 - y^2/5^2 = 1 ... answer is the 1st
put them together and add them up
Step-by-step explanation:
Hello,
y-1=(2-1)/(5-4)(x-4)==>x-y=5
