Find the slope, if it exists, of the line containing the pair of points. (-17,-9) and (-19-18) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The slope is (write an integer or a simplified fraction.)_________ B. The slope is undefined.________
Answers
Answer:
the slope is
Step-by-step explanation:
calculate the slope m using the slope formula
m =
let (x₁, y₁ ) = (- 17, - 9 ) and (x₂, y₂ ) = (- 19, - 18 )
substitute these values into the formula for m
m = =
=
=

Step-by-step explanation:
ΔXYZ is an isosceles triangle & XY = XZ, therefore:
YX' = X'Z
= 20 ÷ 2
= 10 cm
ΔXYZ' is a right triangle, therefore:
XY² = YX'² + XX'²
16² = 10² + XX'²
XX'² = 256 - 100
XX' = √156
= 2√39 cm

Answer:
The remaining solution to the equation is x = 1
Step-by-step explanation:
2x^2 + x - 1 = 2
First set the equation to zero by subtracting 2 from each side:
2x^2 + x - 1 - 2 = 2 - 2
2x^2 + x - 3 = 0
Factor the left side of the equation:
2x^2 + x - 3 = 0
(2x + 3)(x - 1) = 0
Now set each factor to zero and solve:
2x+ 3 = 0
2x+ 3 - 3 = 0 - 3
2x= -3
2x/2= -3/2
x= -3/2 (The given expression)
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
Since we already knew x = -3/2, the missing solution is x = 1.

Answer:
4 hours and 15 minutes
Step-by-step explanation:
We have to find out how long it will take a driver to complete the route.
Time of start the route = 9:50 A.M.
Time of finish = 2:05 P.M.
We can convert the time of finish in 24 hours time
2:05 P.M = 14:05
Now we subtract start time from finish time.
14:05
- 09:50 [borrow 60 minutes to subtract 50 from 05]
04 : 15
It takes 4 hours and 15 minutes to drive the route.
