5x - 5y >= 70
Move the 5x to the right by subtracting 5x from both sides
- 5y >= -5x + 70
Divide both sides by -5 and when you divide by a negative you have to change the inequality sign.
y <= x - 14 Letter B
Answer: 0.9
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that a farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces
When we consider this graph as a straight line, the two points lying on the line would be
(30, 30) and (34, 28) taking n as horizontal and y vertical
Using two point equation we find that
the equation of the line is
Substitute the points as x =n
is the linear relationship between n and y
Answer is B. No matter what the x or y will be the result will be 0. Anything multiplied by 0 is equal to 0.
The average slope (s) on the interval [a, b] is given by
s = (f(b) -f(a))/(b -a)
When there are a lot of computations to do, it is convenient to let a machine do them. The intervals and slopes are ...
[0, 5] : 5
[-3, 3] : 0
[-5, 3] : -2
[-3, 5] : 2
