Answer:
Step-by-step explanation:
37) Take two point from the line.
(2 , 0) & (0,4)

Slope = (-2)
38) (7 , 0) & (3 , 2)

39) The line is parallel to x-axis and so its slope is 0
Slope = 0
40) The line is parallel to y-axis and so its slope is undefined
Slope = undefined

Answer:
x = -6
Step-by-step explanation:
The zero is where the graph crosses the line y=0 (the x-axis). It is also called the x-intercept.
That point is (-6, 0). The x-value there is -6.
__
Some folks like the x-value only; others like the ordered pair. Of course the y-value in the ordered pair is 0, which is what makes it a zero of the function.
Answer:
85 milometers is less than 0.85 litters
Step-by-step explanation:
0.85 litters is 850 milometers or u could say 85 milometers is 0.085 litters witch means 850 milometers(0.85 litters) is more than 85 milometers or 0.085 litters(85 milometers) is less than 0.85 liters.
What do you need help with?
Answer:
Notebooks cost $2.75 and pens cost $1.10.
He can also buy 3 notebooks.
Step-by-step explanation:
In order to find this, we need to create two equations given each of the situations.
3n + 2p = 10.45
4n + 6p = 17.60
Now to solve for n, multiply the top equation by -3 and add together.
-9n - 6p = -31.35
4n + 6p = 17.60
----------------------
-5n = -13.75
n = 2.75
Now that we have the value of notebooks, we can find the amount for pens using either equation.
3n + 2p = 10.45
3(2.75) + 2p = 10.45
8.25 + 2p = 10.45
2p = 2.20
p = 1.10
Finally, to find the number of notebooks that he can purchase, find the cost of a notebook with 3 pens.
n + 3p
2.75 + 3(1.10)
2.75 + 3.30
6.05
Now divide 22 by that number
22/6.05 = 3.63
Since we can't have fractional notebooks, we round down to 3.
