3x - 15 = 105
3x = 120
x = 40
3(40) - 15 + y + 24 = 180
120 - 15 + y + 24 = 180
129 + y = 180
y = 51
f ( - 2 ) = 5 × 3^( - 2 )
f ( - 2 ) = 5 × 1/9
f ( - 2 ) = 5/9
What class is for ? If you tell me I could take out my notes
In the <span>addition process</span> this usually involves:
<span><span>rounding numbers up to the nearest multiple of 10 or 100 </span>subtracting the extras that were added at the end.</span>
In the subtraction process this usually involves subtracting too much and completing the calculation by putting some back.
Answer:
sec A = 5/4
Step-by-step explanation:
Sec of an angle is hypotenuse/adjacent side
In your problem, sec A = 25/20 = 5/4
It helps if you can draw a figure of the problem. Make sure you memorize the definition of each trig function
