Answer:
y + 6 = 2/3 (x - 2)
Step-by-step explanation:
Step 1. Find the slope
m = slope
m = change in y/change in x
m = (y2 - y1)/(x2 - x1)
points: (2, -6) & (8, -2)
m = (-2 - -6)/(8 - 2)
m = 4/6
m = 2/3
Step 2. Create the point-slope equation by using the slope and the first point
Point-slope formula: y - y1 = m(x - x1)
Where m = slope and (x1, y1) = first point
Point-slope form: y + 6 = 2/3 (x - 2)
K= 10(-7) -19
k= -70-19
k=-89
Answer:
-7x
Step-by-step explanation:
==> -12x + 5x.
==> -12+5xx
==> -7x
I’m pretty sure it’s Number 3. Hope I’m Right.
Speed of the ship in the second hour = (62.5 * x ) / 100 kph.
In third hour it is [(62 * x) / 100 ] * x/100]
is 4th hour its is the above * x/100 again so we can now form the equation
62.5x x x
------- * ---- * ---- = 32
100 100 100
62,5 x^3 = 32,000,000
x^3 = 512,000
x = 80 <----- Answer to (a)
(b) Ship travels 62.5 in first hour then this falls by a common ratio of 0.8 each hour so we have a geometric sequence
Dist travelled in 6 hours = a1 1 - r^n
-------- = 62.5* (1 - 0.8^6) / 1 -0.8 = 230.56
1 - r
Answer is 230.56 km
