Answer:
Step-by-step explanation:
Now the key here is manipulating the scale:
For 3 every 2cm = 15mi
Divide by 2 so every 1cm = 7.5mi
So if we had 16.27cm then that would equal 16.27 x 7.5 = 122.025mi on the actual scale
Same for 4: if 1/2cm = 20mi
Then multiply times 2 and every 1cm = 40mi
So 11.73cm x 40 = 469.2mi on the actual scale
Hopefully this is right and it helps!
Well for the first one you have to subtract 3 on both sides so that would make the equation x > -8 (because a negative subtracting a positive is basically a negative plus negative) and so your equations done. For the second one you divide both ides by -4 so your equation would be x < 4 (the sign would be less then or qual to because you divided by a negative)
<u>1 3/10 Because 4/5+2/10= 1 plus 6/20 [3/10] is 1 3/10</u>
Answer:
Decrease, Increase and reflects over the y axis.
Step-by-step explanation:
the function shrinks so it would shorten the period, this frequency would then increase as well when b increases because b is the frequency. it would reflect over the y axis because when graphed it is reflected over the y axis.
-If none of this also makes sense you the answer is correct anyway because this was the correct answer on edmentum/plato.
