Wouldn't you add them all together? for example:
$35 x 12 = $ 420 ( that's the reminding 12 months)
$420 + 75 = $495 (for the connection fee) than work out the 6 months worth
$25 x 6 = $150 (For the 6 months) than plus $495 + 150 = $645.
I see what I did. I didn't realise you add the first answer to get the second.

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

If you flip a coin 3 times, what is the probability of flipping heads 3 times? a. p(3 heads) = 3/8 b. p(3 heads) = 1/6 c. p(3 heads) = 1/8 d. p(3 heads) = 1/2
