Answer:
1. $450
2. $128
Step-by-step explanation:
1. new price = .4 (.4 * original price x)
72 = .16x
x = 450
2. new price = .75 (.75 * original price x)
72 = .5625x
x = 128
E 10 12
x=18*5)14. x=40/4. x=10. y=(15*4)/5 y=60/5 y=12.
resposta : 10 e 12
Answer:
Step-by-step explanation:
A linear graph with y values (height of tree) going up 2.5 with each increase of x (growing season)
This is the model that best fits the graph describing a growth of a plant
Answer: (B) x^3
Explanation:
If you compare the graphs of
all on the interval -1 < x < 0, you'll find that y = x^3 is the smallest when x = -1
Squaring a negative number leads to a positive result, and similarly that happens with x^4 as well. This is because x^4 = (x^2)^2.
Plugging x = -1 into x^3 leads to y = -1 as a result.
