Answer:
-93
Step-by-step explanation:
Step one:
given the expressions
we want (fog)(-3).
but (fog) is
Step two:
fog(-3)= put x= -3 in (fog)(-3)=-8x^2-20x+32+7
Answer:
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.
Step-by-step explanation:
First find the slope by choosing two ordered pairs and using the slope formula:
Now use the Point-slope form of linear equation with the found slope and one of the points to create the equation of the linear function:
The rate of change of a linear function is its <u>slope</u>.
Therefore,
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.
Jake because 45.21×10=452.1 which is not a whole number, and 8.22×10=82.2 which is also not a whole number, but 45.21×100=4521 which is a whole number, and 8.22×100=822 which is also a whole number. When you multiply a number with 1 and 0s behind it (ex: 10,100,1000, etc) You just more the decimal place the number of 0s you have (ex: 2.0×100= 200, 3.5×1000=3500)
Answer:
Option D. T=7/12c+10/3
Step-by-step explanation:
Let
T -----> the temperature in degree Celsius (y-axis)
c ---> the number of cricket chirps,that are counted in a 15-second span (x-axis)
we have the ordered pairs
(32,22) and (44,29)
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to
substitute the given values
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Convert to slope intercept form
isolate the variable y
simplify
0.007 is smaller than 0.07
