From the relation, d is joint proportionaly with r and t.
Thus,d = krt.
Using the first set of given, we could calculate for k.135 = k(45)(3)k = 1
Using the computed value of k.d = krtr = d/ktr = (189)/(1)(3.5) = 54 mph.

Use the fact that 1 axe head = 3.20 trade value.
Let N denote number of axe heads needed to trade for a trade gun.
3.20×N=120.00
》 N=120/3.2 which will give number of axe heads needed. Round to the nearest ones place if you must.

When x=0,

The solution is (0,1)
QUESTION 2
The given equations are:

and

We equate both equations to get:

Group similar terms,



We put x=0 into any of the equations to find y.

The solution is (0,-1).
QUESTION 3
The given equations are:

and
