Given two points 
and 
, the equation of the line passing through them is
This formula, however, only works if the points don't share any of the two coordinates. Otherwise, one of the two conditions is true:
And at least one of the denominators in the formula above will vanish.
So, if two points share the same x coordinate, they lie on the vertical line x=k, where k is the shared x coordinate.
Similarly, if two points share the same y coordinate, they lie on the horizontal line y=k, where k is the shared y coordinate.
In your case, the x coordinate is the same, so the points lie on the vertical line x=10.
Answer:
Step-by-step explanation:
Given:
Hallway A:
1/10 bulbs
2/10 small bushes
7/10 tree seedlings
Hallway B:
2/10 bulbs
1/10 small bushes
7/10 tree seedlings.
Total flatbed of tree seedlings = flatbed of tree seedlings in hallway A + flatbed of tree seedlings in hallway B
= 7/10 + 7/10
= 14/10
= 1 × 2/5 flatbed of tree seedlings
1) given function
y = - 2 ^ ( -x + 2) + 1
2) domain: domain is the set of the x-values for which the function is defined.
The exponential function is defined for all the real numbers, so the domain of the given function is all the real numbers.
3) x-intercept => y = 0
=> y = - 2 ^ ( -x + 2) + 1 = 0 => 2^ ( -x + 2) = 1
=> - x + 2 = 0 => x = 2
The x-intercept is x = 0
4) y-intercept => x = 0
=> y = - 2 ^ ( -x + 2) + 1= - 2 ^ ( 0 + 2) 1 = - (2)^(2) + 1 =- 4 + 1 = - 3
=> The y-intercept is - 3
5) limit when x -> negative infinite
Lim f(x) when x -> ∞ = - ∞
6) limit when x -> infinite
Lim f(x) when x - > infinite = 1
=> asymptote = y = 1
7) range is the set of values of the fucntion: y
Given that the function is strictly decreasing from -∞ to ∞, the range is from - ∞ to less than 1
Range (-∞,1)
G) X=4
H) X=2
I) X=-3
J) X=2
