Step-by-step explanation:
I. x - y = 4 --> y = x - 4
II. x + y = 4 --> y = 4 - x
Solution is x = 4 and y = 0
The area of a triangle could be calculated by multiplying the half base by the height.
Area = 0.5 * 5.05 * 2.4 = 6.06 square units.
Q1)
is the function representing the weekly paycheck of salesman A a proportional relationship?
p - function
s - number of sales
Salesman A earns £65 per sale. Therefore if he earns s number of sales, the total amount he earns is 65*s = 65s
Lets assume for s number of sales he receives his maximum weekly commission, therefore the equation for A's weekly payment is;
p = 65s +1300
to determine if p and s are proportional to each other, it should take the form of equation p=ks
where k is a constant. If we graph p=ks, then k is the slope that is a constant and the line should pass through the origin, which means that y intercept is 0.
however in this equation there is an intercept of +1300, therefore p and s are not proportional values.
Q2)
For salesman B he has a weekly base salary of £300 and commission of £40 per sale. Then the salary is fixed however for s number of sales, the commission he will receive is 40*s = 40s
the function for B's payment is as follows;
p = 40s + 300
This equation if we take it as a graph equation with p and s as y and x coordinates respectively, the equation we get is of one with an intercept of +300
therefore if we graph it, the line will not pass through the origin which means that the p and s values are not proportional to each other.
Q3)
Salesman C receives a weekly salary of £900. This is a fixed amount and does not vary depending on the sales. Therefore this is anyway not proportional as p function is not affected by s value.
therefore p and s are not related, hence they aren't proportional.
p = 900
