Answer:
(0, - 23 )
Step-by-step explanation:
Find the equation of the line in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 72, 25) and (x₂, y₂ ) = (- 36, 1) ← 2 ordered pairs from the table
m = 
= 
= - 
, thus
y = - + c
To find c substitute any ordered pair into the equation
Using (- 54, 13 ) , then
13 = 36 + c ⇒ c = 13 - 36 = - 23 ← y- intercept
Thus coordinates of y- intercept = (0, - 23 )

Step-by-step explanation:
B, (x-5)square =21
Answer:
-1/3
Step-by-step explanation:
To find the slope we use
m= (y2-y1)/(x2-x1)
= (7 - -3)/(-10 -20)
= (7+3)/ -30
= 10/-30
= -1/3
- Force=0.02N=F
- Acceleration=a=8m/s^2
- Mass=m
According to Newton's second law

Answer:
Step-by-step explanation:
Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...
x + (x+40) = 1180
2x = 1140 . . . . subtract 40
x = 570 . . . . . .divide by 2
x+40 = 610 . . . . the speed of the faster plane
The two speeds are 570 mph and 610 mph.
