Step-by-step explanation:
It is a parabola, Every y has a unique x value
-3x-2x+12x+5x=-9
-5x+12x+5x=-9
-5x+17x=-9

x=-9+12
×=-3
Answer:
Step-by-step explanation: The area of the bedroom is
A=7yd^2
The total cost is the sum of the price rates times this area.
C=A•($21+$5)/yd^2
where C is total cost.
C=7yd^2•($21+$5)/yd^2
C=$182
Let x= number of days
1.5x+6=45
subtract 6 from both sides
1.5x=39
divide both sides by 1.5 to get
x=26
it will take 26 days for the plant to reach 45 inches in height
Answer:
Ida makes $ 6960 in 5 weeks.
Step-by-step explanation:
Let the profit of the first week is p.
p = $ 600
Total profits of the five weeks
= p + (p + 0.15p) + (p + p +0.15 p) + (p + p + p + 0.15 p) + (p + p + p + p + 0.15 p)
= 11 p + 0.6 p
= 11 x 600 + 0.6 x 600
= 6600 + 360
= $ 6960
So, Ida makes $ 6960 in 5 weeks.
