Given h(x) = 3x - 2, find h(7)=

19

Explanation: In this problem, we're given the function h(x) = 3x - 2 and we are asked to find h(7).

To find h(7) or the value of the function when x = 7, we simply substitute 7 in for x  in our function. So we have 3(7) - 2 or 21 - 2 which equals 19.

So h(7) or the value of the function when x = 7 is 19.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
