1) solve, using the substitution method.

d + e = 2
d – e = 4

a) the solution is (3, –1).

b) there are an infinite number of solutions.

c) there is no solution.

d) the solution is (5, 1).

2) solve, using the substitution method.

x – 2 = –2y

a) (3, -1/2)
b) (0, - 2)
c) (0, -11/2)
d) (7, -5/2)

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
