Answer:
If the increases are roughly the same, then linear is best. If the multiple factor is roughly the same, then an exponential is best. If the rate at which the increase increases is roughly the same (so A-B=1, B-C=3 C-D=5.2), then quadratic is best.
Step-by-step explanation:
Answer:
N= -2
Step-by-step explanation:
N+10=8
-10= -10
N= -2
We have

and

so the equation is indeed exact. So we want to find a function
such that


Integrating both sides of the first equation wrt
gives

Differentiating both sides wrt
gives

So we have

or

Answer:
Step-by-step explanation:
Given two similar triangles.
Corresponding parts of similar figures have same ratio.
<u>Use ratios to find the value of x:</u>
- (4x - 5)/(x + 7) = 35/12.5
- (4x - 5)/(x + 7) = 14/5
- 5(4x - 5) = 14(x + 7)
- 20x - 25 = 14x + 98
- 20x - 14x = 98 + 25
- 6x = 123
- x = 123/6
- x = 20.5
<u>Find the value of FG:</u>
ANSWER
The x-coordinate of the solution to the system of equations is 3.
EXPLANATION
The solution to the system of equations is the point of intersection of the straight lines that represents the given system.
From the graph the two straight lines intersected at:
(3,2)
Hence the solution to the system of equations is (3,2)
The x-coordinate of the solution to the system of equations is 3.
