<span>y = 10x + 2
x = 3

y = 10*3 + 2
y = 30+2
y = 32</span>

You would plug in 3 for x, which gives you y = 10(3) + 2, and then you would use PEMDAS, which means you multiply 10 with 3 and then add two which is 32. Therefore y would equal 32. :D :D

Find the annual percent increase or decrease that y = 0.35(2.3)x models. (1 point) A.230% increase B.130% increase C.30% decreas
ipn [44]

Answer: B. 130% increase


Step-by-step explanation:

Given function :  y=0.35(2.3)^x

If x represents the number of years, we have to determine the two values of y in consecutive terms to determine if the value of y increases or decreases after a year.


This function is equivalent to the exponential growth function


y=A(1+r)^x, where A=0.35 and (1+r)=2.3, [A= initial amount , r=annual percent increase]

Thus,

\Rightarrow\ r=2.3-1\\\Rightarrow\ r=1.3\\\Rightarrow\ r=1.3\times100\%=130\%

Hence, the annual percent increase is 130%.

PLEASE HELP I DONT UNDERSTAND I HAVE A FEW MIN TO SUBMIT
Lunna [17]

Answer:

Increasing: (\infty, -1) \cup (2, \infty)

Decreasing: (-1, 2)

Step-by-step explanation:

So when an equation has and odd degree, it will go in the opposite direction on both ends, so if y went towards infinity as x went towards infinity, then y would go towards negative infinity as x goes towards negative infinity. In this case, by looking at the graph it has an odd degree, due to opposite end behaviors, although on both ends it's increasing because even though it appears that it's going down on the left side, that's only if you start from the right and go towards the left. So it's really increasing from negative infinity to -1, and then it decreases from -1 to 2, until it once again starts increasing from 2 to infinity. This can be represented as (-infinity, -1) U (2, infinity) for increasing and (-1, 2) as decreasing
