Answer:
x^2 +3x +3
Step-by-step explanation:
(9x^2+3x+6)–(8x^2+3)
Distribute the negative sign
(9x^2+3x+6)–8x^2-3
Combine like terms
9x^2–8x^2+3x+6–8x^2-3
x^2 +3x +3
The answer is 90,000. Just remember 5 or above, give it a shove, and for or below let it go. Because 85 has a five at the end you push it up to 90. Same thing with 85,000 or 85,001. You shove it to 90. If it was 84,000 or 84,999 you would let it go to 80,000. Hope that helped!
Answer:
y = 0.36x + 4200.00
15100.00 miles.
Step-by-step explanation:
If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).
So, the equation will be
⇒
⇒
⇒
⇒
⇒ y = 0.36x + 4200.00 ........... (1) (Answer)
Now, for y = $9636.00, from equation (1),
9636 = 0.36x + 4200
⇒ 0.36x = 5436
⇒ x = 15100.00 miles. (Answer)
Answer:
C. 20 feet
Step-by-step explanation:
The question has given you tan∅ = 20/50. You know that tan is opposite over adjacent. So if the opposite end is 20, that means the tree is 20 feet tall and the girl is <em>50 feet away</em>.
