x = 8 and x = –8
Hi.
So to solve this first you have to do 1.60 or 1.6 times 6= 9.6 or 9.60.
Everything costed 24.60.
24.60 minus 9.60=15
There are 6 pendants so 15/6= 2.5.
So each pendant costed 2.5
4x+3y=19
3x-5y=7
(3)4x+3y=19
(-4)3x-5y=7
12x+9y=57
-12x+20y=-28
----------------------
29y=29
------------
y=1
4x+3(1)=19
4x+3=19
-3 -3
--------------
4x=16
--------
x=4
9q-8q=18
q=18 and this is the answer- it says I need twenty characters soooooo
Y-y1=m(x-x1)
find slope
(y2-y1)/(x2-x1)
so
(-4,-1)
(3,-3)
slope=(-3-(-1))/(3-(-4))=(-3+1)/(3+4)=-2/7
y-(-1)=-2/7(x-(-4))
y+1=-2/7(x+4)
