Answer:

10x^2 +2x -9

Step-by-step explanation:

Group things that are alike and simplify

(3x^2+7x^2) = 10x^2

(2x) nothing to add or subtract with it so it stays positive 2x= +2x

(-5-4) = -9

Then put the answer from highest degree to lowest

Help Please?! I don’t know how to do this
Fofino [41]

Domain 0≤x≤12   this means the domain (x values) are between x=0 and x=12 and you started measuring the degree of temperature starting at a time of 0 and stopped measuring the temperature at a time of 12 hours


Range -4≤y≤4   this means the range (y values) are between y=-4 and y=4. The range is referring to the degree in celcius based on what time you measured it


Hope this helps!

The position of an object at time t is given by s(t) = 3 - 4t. Find the instantaneous velocity at t = 8 by finding the derivativ
zysi [14]
For this case, we have that the equation of the position is given by:
 s (t) = 3 - 4t

 To find the velocity, we must derive the equation from the position.
 We have then:
 s' (t) = - 4

 Then, we evaluate the derivative for time t = 8.
 We have then:
 s' (8) = - 4
 Answer:
 
the instantaneous velocity at t = 8 is:
 
s' (8) = - 4

Write a mixed number that is equivalent to 16/3.
mars1129 [50]
A mixed number is an integer--whole number--in front of a fraction. To calculate this, you have to divide the numerator by the denominator and put the remainder over the denominator. 

Since 3 goes into 16 wholly 5 <em />times with 1 left over, 16/3 = 5 1/3.

Hope this helps!
