Answer:

Step-by-step explanation:
Let
x----> the temperature in degrees Fahrenheit
y ---->insect chirping rate in times per minute
we have the ordered pairs
(82,61) and (91,124)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
 
substitute the values
 
 
step 2
Find the equation of the line
we know that
The equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have
 ---> the units are chirps per minute/degree F
  ---> the units are chirps per minute/degree F
take the point (82,61)
substitute and solve for b



substitute

 
        
             
        
        
        
Answer:

Step-by-step explanation:
We have been given the function

From the rational zeros theorem, we have

From the given function,
Leading coefficient = 2
Factors of 2 are 1,2
Constant term = 18
Factors of constant term = 1, 2, 3, 6, 9, 18
Hence, we have

 
        
             
        
        
        
Answer:

Step-by-step explanation:
For the first few exponents multiply and the rest they add because like terms.
The trick is that when you raise a power to a power you multiply. Otherwise you add if the base value is the same.
 
        
             
        
        
        
Answer:
18,502 no se no entendi muy bien 
Step-by-step explanation:
 
        
             
        
        
        
So use cancelation
multiply first equation by 2
2x+8y=10
times 2
4x+16y=20
now add
4x+16y=20
<u>-4x-9y=-13   + 
</u>0x+7y=7
7y=7
divide by 7
y=1
subsittue
2x+8y=10
2x+8(1)=10
2x+8=10
subtract 8 from both sides
2x=2
divide by 2
x=1
x=1
y=1
