The temps that we know are colder than -5deg C 

first anything below or less than -5degC will be colder in temperature because it has a lower or smaller value, so it is colder overall. 

3 examples would be x<-5deg C

x= -6deg C
x= -7deg C
x= -8deg C

so plugging in x value we get -6<-5   -7<-5    -8<-5

If you are needing anything else please just ask! Thank you!

Solve for x: −3(x + 3) = −3(x + 1) − 5.
erastova [34]
-3(x+3)= -3(x+1)-5
-3x+9=-3x+3-5 
so you would have just distributed then you combine like terms and get
-3x+9=-3x-2
then add two to both sides and get
-3x+9=-3x-2
-3x+2=-3x+2
-3x+11=-3x
+3x+11=+3x
0x+11=0x 
so 11+0x 
divide both by zero and you get x+0

A wheelchair ramp rises 1.5 feet for every 18 feet of horizontal distance it covers. Find the rate of change of the ramp
Ierofanga [76]
By definition the rate of change of a function is given by:
 AVR =  \frac{Change In Y}{Change In X}
 Or equivalently:
 AVR = \frac{y2 - y1}{x2 - x1}
 Substituting the values given in the problem we have:
 AVR = \frac{1.5}{18}
 Rewriting we have:
 AVR = 0.08
 Answer:
 
the rate of change of the ramp is:
 
AVR = 0.08

A town has a population of 8000 and grows at 3% every year. To the nearest tenth of a year, how long will it be until the popula
Alexxx [7]

Answer:

It will take approximately 34 years

Step-by-step explanation:

If a town population is 8000 and grows 3% annually.

How long will it take to reach 16300

growth is 16300 - 8000 = 8300

using simple interest formula

SI = (P × r × t)/100

8300 = (8000 × 3 × t)100

8300= (80 × 3)t

8300 = 240t

t = 8300/240

t ≈ 34 years to the nearest tenth
