3.50x + 266 = 406
↓
40x
The answer is 40. She needs to sell 40 more bracelets to reach her goal.
The following statements in this case are correct:
1) The independent variable is t.
2) The dependent variable is f (t).
3) When f (2) = 1,323, the 2 represents "the year 2002," and the 1,323 represents "1,323 tons of garbage produced."
4) When f (4) = 1,458.6, the 4 represents "the year 2004," and the 1,458.6 represents "1,458.6 tons of garbage produced."
Note: for statements 3) and 4) the following is done:
f (2) = (1200) * (1.05) ^ 2 = 1323
f (4) = (1200) * (1.05) ^ 4 = 1458.6
Answer:
3y +22
Step-by-step explanation:
y + 6 + 2(y + 8)
Distribute the 2
y+6+2y+16
Combine like terms
3y +22
Answer:
Pencils: 7 boxes
Erasers: 5 boxes
Step-by-step explanation:
She should buy 70 pencils and 70 erasers.
There are 7 pencil boxes for 70 pencils.
There are 5 eraser boxes for 70 erasers.
These are the smallest number of boxes she can buy without getting a fraction of a box.
f(x) = 3x²
g(x) = 4x³ + 1
f(g(x)) = 3.(4x³ + 1)²
As we know
(a + b)² = a² + 2.a.b + b²
So,
(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² =
f(g(x)) = 3.()
The degree is the maximum exponent, so, 6.
