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:
x is greater than or = to 8
Answer:
She's been charged 84 dollars
Step-by-step explanation:
Let's call each month m
if every month it deducts 7 dollars, then to find how much has been charged after a year, we do
-7 * 12 = -84
It will just be -7/12 because anything times 1 stays the same
m<1=23
m<2=90
m<3=67
m<4=113
m<5=67
the square means it is 90° so 2 is 90°.
all of the angles combined equals 360 so.
360-67-90= 203
since there is a straight line splitting down the middle. m<4=180-67=113
so m<4=113
now you would go 360-67-113-90=90 so
m<1 + m<3 =90
180-90-67=23.
m<1=23
360-67-23-90-113=67
m<3=67
