La respuesta es B a+10b+6c=62
The slope-intercept form:
m - slope
b - y-intercept
Convert 2x + 5y = 10 to the slope0intercept form:
<em>subtract 2x from both sides</em>
<em>divide both sides by 5</em>
Let 
and 
We have 
Therefore
We have the equation of a line:
Put the coordinates of the point (5, 1) to the equation of a line:
<em>subtract 
from both sides</em>
Answer: 
Answer:
y= 704.5x - 409
Step-by-step explanation:
Complete question is : . Complete the equation for the relationship between the altitude and number of hours.
SOLUTION
By plotting altitude on y-axis and time or duration of travel on x-axis of the graph, we will have the the location of Nour at t = 0 will be represented by (0, -409)
when t = 2 hours location points will be at (2, 1000).
As you know, at a constant rate her altitude is increasing , we will have a linear graph with equation y = mx + b --> eq(1)
Slope of the line is given by:
m= (y-y') / (x-x') => (1000+409)/(2-0)
m= 704.5
y-intercept 'b' is -409
Therefore, the eq(1) will become
(1)=> y= 704.5x - 409
Where, 'y' represents Nour's altitude(in meters) relative to sea level after 'x' hours
4y-1.5=2y+2.5
add 1.5 to both sides
4y=4+2y
subtract 2y from both sides
2y=4
divide by 2 on both sides
y=2
