Answer:
-1
Step-by-step explanation:
-2 divided by 2 = -1.
A negative divided by a positive equals a lesser negative.
Answer:
2nd answer option
Step-by-step explanation:
the domain is the interval or set of valid x values. the range is the same for valid y values.
so, what is the smallest x value we see in the functional graph ?
x = 0
there is no functional value for any x smaller than that.
and then the function goes on and on to the right in all eternity. that means it goes to infinity.
so, domain = [0, infinity)
please consider the round bracket at the end, because "infinity" is not a number.
now for the range and the y values.
in this case I start to ask for the largest y value.
y = 4
for no x value do we get a larger y value.
but it goes down and down in all eternity, going also to infinity, but -infinity (down is negative for y).
so, the range = (-infinity, 4]
"-infinity" is also not a number and therefore not included (hence the round bracket).
Answer:
88%
Step-by-step explanation:
22/25 = 0.88
0.88 x 100 = 88%
Answer:
It is 
degrees Fahrenheit when the crickets are chirping 
times a minute.
Variables 
and 
y-intercept 
slope 
Step-by-step explanation:
As the chirps are 
times per minute for 
degrees Fahrenheit we will consider it in 
.
Now when the chirps are 
times and temperature is 
degrees we consider it 
.
To find the slope we can use point-slope formula.
Where 
is the slope and 
To find y-intercept we will plug out the value of slope in 
choosing point .
So 
And the equation is 
To calculate temperature for chirpings we have to plug 
and 
in our above equation which is in form of
degrees Fahrenheit.
Finally we have :
Temperature degrees Fahrenheit.
With variables and
y-intercept and
slope
