Answer:
Step-by-step explanation:
the zeros are -5, and -6
x+ 6 = 0 so x= -6 ; at this zero the graph crosses the x-axis because the degree for (x+6)^1 is 1 the multiplicity is 1
x+5 = 0 so x= -5; at this zero the graph crosses the x-axis because the degree for (x+5)^3 is 3 and the multiplicity is 3
Useful facts to know ;
If the multiplicity is odd the graph crosses the x-axis,
if the multiplicity is even the graph touches the x-axis and go
Step-by-step explanation:
We are given the co-ordinates,
x : -2, -1, 0, 1, 2
y : 8, 5, 2, -1, -4
According to the graph, we see that this function represents a straight line.
The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.
So, taking any two points we will find the equation of the straight line.
Consider, (0,2) and (1, -1). Now, slope is given by,
m =
i.e. m = -3
Now, we will find the y-intercept of this equation using (0,2) and m = -3,
i.e. y = -3x + c
i.e. 2 = c
Hence, the equation of the straight line is y = -3x + 2.
Answer:
633.58
Step-by-step explanation:
2890 miles / 13 mpg = 222.31 gallons used
222.31 gallons * 2.85 per gallon = 633.58
First change the mixed fraction to improper fraction, and then find common denominators.
5 1/2 = 11/2
4/9(2/2) = 8/18
11/2(9/9) = 99/18
-------------------------------------------------------------------------------------------------------------------
Next, subtract
99/18 - 8/18 = 91/18
91/18 = 5.05
-------------------------------------------------------------------------------------------------------------------
As you are finding the best estimate, 5.05 is closest to 5, which makes your answer D)

add 4n and 5n, which is 9. 9n=-9, and if u divide both sides by nine, n=-1
