Replace all the x values with -3 

f(-3)=-2(-3)^2+5(-3) 
f(-3)=2(9)-15
f(-3)=18-15 
f(-3)=3 

Hope I helped :)

Plug -3 in for x. the equation should look like this
f(-3)=-2(-3)^2+5(-3)

simplify by multiplying and you get
f(-3)=6^2-15

now apply the exponent
f(-3)=36-15

finish it off by subtracting and you get
f(-3)=21

Answer:

1.   y= 25400(1 + 0.11)^x

2.  2019

Step-by-step explanation:

1. y = a(1 + r)^x       <em> </em>

<em>(exponential growth formula :</em>

<em>a = initial value (the amount before measuring growth or decay) </em>

<em>r = growth or decay rate (usually represented as a percentage and expressed as a decimal) </em>

<em> x = number of time units that have passed)</em>

y= 25400(1 + 0.11)^x

so in 1 year, in 1996, we would say

y=25400(1+0.11)^1

y=25400(1.11)

y=28194

2. I found the answer by plugging in numbers into x

with x = 24

y= 25400(1+0.11)^24

y= 310874

so in 24 years, the population will surpass 302438 which would be 1995+24= 2019

The degree of 9x^5y^6+4x^2y^3-17xy
Mariulka [41]

To tell the degree of the polynomial, we look for the term with the highest degree. We find the degree by combining the exponents of each variable in a term.

<h3><u>The degree of this polynomial is 11.</u></h3>

(5 + 6 = 11)

Do the rays BA and AB define the same ray? In complete sentences, explain why the two rays are the same or why the two rays are
Deffense [45]
Rays are named according to their endpoints, the first one named is the "starting" endpoint, the second one is the one that will continue on into infinity.  Therefore, ray BA has a terminal endpoint at B and goes through point A into infinity.  Ray AB has a terminal endpoint at A and goes through point B into infinity.  Definitely NOT the same ray.
