I don't see how the numbers on the chart work with the table because I
got 1(1), 3(2,2,2), 6(4,4,4,4,4,4), 10(6,6,6,6,6,6,6,6,6,6), 5(8,8,8,8,8), 3(10,10,10) ,1(12)
that is how i see the chart, sorry if i got it wrong.
Answer:
Step-by-step explanation:
tanA = sinA/cosA = (4/7)/(3/7) = 4/3
x= 13.5
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
<em>Check:</em>
f(13.5) = 2(13.5) + 9= 27 + 9 = 36
-2
Just use 6-8 and you will get - 2
Check again with - 2+8 you will get positive 6
