Answer:
An equation that can be used to model these data is of the form: y = A cos B(x - C) + D,
where A,B,C,D, are constants, y is the temperature in °C and x is the month (1–12).
1) -33/19
2) 8/9
3) -43/8
4) 1/17
5) -5
These should be correct
You are adding:
5a + 2 a+3
------------ + ---------
6a 3a
The LCD here is 6a, so we must mult. numerator and denom. of the 2nd fraction by 2:
5a + 2 2(a+3) 7a + 8
------------ + --------- = -------------- Please note: either write this result as
6a 2(3a) 6a shown, or include parentheses in your
answer: (7a+8) / (6a)
Can you please take a picture
Answer:
2a-9=2a-9
<em>Infinitely Many Solutions</em>
Step-by-step explanation:
2(a-8)+7=5(a+2)-3a-19
<em>Use Distributive Property</em>
2a-16+7=5a+10-3a-19
<em>Combine Like Terms</em>
2a-9=2a-9
