3c = 12.69
where c = # of greeting cars
The answer is 4.5*5*-2= -45 Thanks!
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Answer:
2.8 miles higher the plane go without leaving the troposphere?
Step-by-step explanation:
Troposphere height on different locations= 6-12 miles
plane altitude at present flight = 5.8 miles.
Troposphere deepness from the present flight= 8.6 miles
So from present altitude till troposphere= 8.6-5.8= 2.8 miles
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =5 and y_1 =1
m the slope m= -1 (same slope for the line : x+y=9 because this lines are parallel and you can write y=-x+9
an equation for this line is : y-1 = -(x-5)
