Answer:
16) 2
17) -5
18) doesn't exist
19) doesn't exist
20) doesn't exist
21) 3
22) 4
23) 6
Step-by-step explanation:
16) as you move towards -9, the function adopts the value 2
17) as one moves towards x = -6 , from both sides (right and left) the function goes to the value -5
18) As one moves towards x = -4 (from the right and from the left, the functions seems to diverge towards + ∞. So normally the convention for limits stipulates: Undefined or Doesn't exist
19) f(-4) doesn't exist (for same reasons as above (there is a singularity here)
20) As one moves towards 2 from the right, the function gets towards the value 3, while approaching from the left the function goes towards the value 5. So formally we say that the limit doesn't exist (from the left and from the right limits don't agree)
21) f(2) is the well defined value of 3
22) approaching x= 4 from the right and from the left both lead towards the value 4.
23) f(4) is 6
Answer:
see explanation
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = 
, hence
y = x + c ← is the partial equation
to find c substitute (4, - 3) into the partial equation
- 3 = 5 + c ⇒ c = - 3 - 5 = - 8
y = x - 8 ← equation of line
Answer:
x > 9/20
Step-by-step explanation:
4/5 + x + 1 > 9/4
multiply both sides by 20 to eliminate the fractions
16 + 20x + 20 => 45
Combine like terms
20x + 36 > 45
Subtract 36 from both sides
20x > 9
Divide both sides by 20
x > 9/20
Answer:
Step-by-step explanation:
7 x > 4 x + 100
7 x - 4 x > 100
3 x > 100
x > 100 : 3
x > 33.33
<u><em>Answer: they have to sell 34 pizzas to make a profit.
</em></u>
There are 10 digits 0 1 2 3 4 5 6 7 8 9 if we can't use 0 and 1 then there are only 8 choices for the first digit and only 2 choices for the second digit and 10 for the third so there are 8*2*10 =160 possibilities. I think ???
