Answer:
The slope is -.3125 and the y intercept is 25
The x intercept is 80
Step-by-step explanation:
2.5x+8y=200
We want to get this in slope intercept form so we will solve for y
Subtract 2.5x from each side
2.5x-2.5x+8y=-2.5x +200
8y = -2.5x +200
Now divide by 8 on both sides
8y/8 = -2.5x/8 + 200/8
y = -.3125x +25
This is in the form y = mx+b where m is the slope and b is the y intercept
The slope is -.3125 and the y intercept is 25
To find the x intercept, set y = 0 and solve for x
2.5x+8y=200
2.5x = 200
Divide by 2.5 on each side
2.5x/2.5 = 200/2.5
x =80
Answer:
y1= 0, y2= 5/3
Step-by-step explanation:
Remove the parentheses and multiply
then cancel the equal terms
collect the lie terms
move the variables to one side
divide both sides by two
split into possible cases
then solve the equation to get
y= 0 and
y= 5/3
Answer:
Answer is 91.5%
Step-by-step explanation:
In 1963= 10,000 sq miles; In 2001= 850 sq miles
- Now applying formula of percentage of decrease we get:
% = Decrease in Amount/ Actual Amount
- Applying values in formula:
= 10000-850/10000
= 9150/10000
% = 0.915
In percentage we get 91.5%
