Answer:
360 cents or $ 3.6
Step-by-step explanation:
Let x be the original cost ( in cents ) of each note book,
After reducing the price by 30 cents,
New cost of each book = x - 30,
According to the question,
3x = 4(x-30) ( ∵ total cost = number of books × cost of each book ),
3x = 4x - 120
3x - 4x = -120
-x = -120
x = 120
Hence, the cost of three books = 3 × 120 = 360 cents or $ 3.6
Answer:
It should be 16.416 (round if needed)
Explanation:
You find this using tangent because the diagram prompts you to use the angle, the opposite side of the angle, and the adjacent side. Tan= opposite/ adjacent
So you use tan46=17/x
Get x by itself
x= 17/tan46
^^ you can plug that into a calculator
Hope this helps
Answer: No
Step-by-step explanation:
The question is whether 3(4x+2) could ever equal 6(2x+2). So let's set them equal to each other and find if there is a value of x, the days, where they are equal.
3(4x+2) = 6(2x+2)
12x + 6 = 12x+2
6 = 12?? No
They will bnever be at the same height. They are growing at the same rate (12x) but starting at different heights (6 and 12)
Answer:
D. g(x) = 2-x^2
Step-by-step explanation:
g(x) seems to be a vertical translation of f(x).
f(x) = 5-x^2
g(x) = 5-x^2-3 (subtract 3 as a translation down 3 units)
g(x) = 2-x^2
