Answer:
b
Step-by-step explanation:
Find the negative reciprocal of the given line's slope in order to determine what the slope of the line will be.
-2/5 -> -5/2 -> 5/2
Your line now looks like this: y = 5/2x + b
Now, substitute the given point into the y and x variables and solve for b.
y = 5/2x + b
-3 = 5/2(2) + b
-3 = 5 + b
-8 = b
You are now done. The line is y = 5/2x - 8.
Without calculating, this would be about 9 because 54/6=9
Answer:
-2
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b
where y is the variable on the vertical axis, x is the variable on the horizontal axis, m is the slope of the line = change in vertical axis / change in horizontal axis, b is the y intercept.
Given that the quantity of apples were measured on the horizontal axis and the bananas on the vertical axis. Therefore let y represent the quantity of bananas and x represent the quantity of apples. The price of banana is $0.75 while that of apple is $1.50, Hence:
0.75y + 1.5x = 12
0.75y = -1.5x + 12
y = -2x + 16
Hence comparing with y = mx + b, the slope of the budget line is -2
Answer:
A. he sold the the car for 1350000
B. his cost price is 1500000
Step-by-step explanation:
A. 150000---> 10%
x-----> 90%
cross multiplication: x=150000×90/10=1350000
B. 10%( price) +90%(price)
1350000+150000=1500000
