This statement is true. Flipping a fraction is usually used when a fractions needs to be divided by another fraction.
Answer:
w = 5
y = 4
Step-by-step explanation:
w + y = 9
3w - y = 11 ( + )
________
4w + 0 = 20
4w = 20
w = 20 / 4
w = 5
Substitute w = 5 in eq. w + y = 9,
w + y = 9
5 + y = 9
y = 9 - 5
y = 4
Answer:
y=0.8x
Step-by-step explanation:
take two points from the graph
(5,4) and (0,0)
then do y2-y1/x2-x1
4-0/5-0
4/5=.8
There are three things you have to know:
- A function is convex when its second derivative
- A function is concave when it second derivative
- The derivative of a power,
, is 
So, the first derivative is
and the second derivative is
This implies that the second derivative of a parabola is constant, and of course that 2 doesn't change the sign of 
.
Flourish- 120x
Green Thumb- (70x)=1600
Flourish- 120*35= $4200
Green Thumb- (70*35)+1600= $4050
It would be less expensive to hire Green Thumb Landscapers. There is a $150 difference between the two
It would take 32 hours of work for the cost to be the same for both companies<span />
