Answer:

Step-by-step explanation:
f(x) = −3(x² - 2x + 1) + 3
f(x) = −3x² + 6x - 3 + 3
f(x) = −3x² + 6x
** The above answer is written in reverse, which is the exact same result.

The answer to this question is D: 2. To solve this, you must work backwards, and what's the oppsite of addition? Subtraction! Take 2.34, your final answer, and subtract .34 from it, and you end up with 2! I hope this helped! Could I possible get brainliest?
Answer:

Step-by-step explanation:
We want to find the rational number which is equal to
.
Let
....eqn(1)
Multiply both sides by 10
.....eqn (2)
Subtract eqn (1) from eqn (2)


Divide both sides by 9.

Answer:
Step-by-step explanation:
Givens
d1 = d
d2 = 75 - d
r1 = x
r2 = x + 7
t = 3
Equation
x*t + (x + 7)*t = 75
This equation represents the total distance travelled. Neither one of the cyclists have gone 75 miles, but they both have gone distances that equal a total of 75 miles.
Solution
3x + (x + 7)*3 = 75
3x + 3x + 21 = 75
6x + 21 = 75
6x = 54
6x/6 = 54/6
x = 9
Answer
The first cyclist is going 9 miles / hr
The second cyclist is going 16 miles / hour
He would be 15 years old depending on his birthday if he has a late birthday he would be 14 years and if he had a early birthday he would be 16 years old
