Answer:
r=3
Step-by-step explanation:
First we add 2 to both sides.
That leaves us with 10r=30
Then we can divide both sides by 10
r=3
Answer:
a=-4, b=-4. (-4, -4).
Step-by-step explanation:
-3a+7b=-16
-9a+5b=16
-------------------
-3(-3a+7b)=-3(-16)
-9a+5b=16
---------------------------
9a-21b=48
-9a+5b=16
------------------
-16b=64
b=64/-16
b=-4
-3a+7(-4)=-16
-3a-28=-16
-3a=-16+28
-3a=12
a=12/-3
a=-4
Answer:
Vertex = 1,2
it is shifted 2 units up and to the right 1 unit
it is a downward parabola (max at (1,2) going down
Step-by-step explanation:
Glass bottles =total number of bottles - numeber of bottle of plastic
gass bottles=50-19=31 bottles of glass.

percent of the glass bottles=(31 bottles * 100%) / 50 bottles=62%
Answer: the percent of the bottles of glas is 62%
If your looking for slope Intercept form. y = 2/3x + 6.67. and
y = 2x + 4
I think
