the real solutions for the equation are -
Step-by-step explanation:
=
= 0
We can write 64 as
+ = 0
using the identity ( )
we get,
=
= ....................(1)
solving the quadratic equation ,
=0
solutions of this quadratic equation can be obtained by
let use y for factors
<u /> ..................(2)
from the equation 1 we have,
which gives solution
and from equation 2 we got
so the real solutions for the equation are -
Answer:
slope = x=4
the slope is undefined
Step-by-step explanation:
<span>Remember, the domain of a function is all of the x values in
the (x,y) coordinates. For this, let’s take a few bench mark coordinates. (0,0)
(1,2.5)(2,0) (3, -9). Those definitely aren’t all real numbers, so eliminate A.
X is not only less than or equal to 0, so eliminate C. </span>
<span>It’s B.</span>
Answer:
32
Step-by-step explanation:
So the order of the points is: GHJK
GH = x+10 =JK
HJ=8
JK=2x-4
JK = x+10=2x-4
x+10=2x-4
10+4=2x-x
x=14
GH= 14+10 =24
GJ = GH +HJ = 24+ 8=32
