40) Consider the steps to simplify the expression. What property of operation is used in Step 2? Expression: -4% +7-34 Step 1: = -47+7+43 (-34) Step 2:= -45 Step 3: = 4+ (3)+(-3)+(-7)+7 Step 4:= -4 +63)+(-7)+(-3) +7 +7 Step 5:= -4 + (-1) + (-3) + 7 Step 6: = -8 +7 Step 7: = -1 A) Apply the associate property of addition, B) Apply the commutative property of addition. C)The opposite of a sum is the sum of it's opposites. D) Subtracting a number is the same as adding the inverse.​

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
