Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:
Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is
Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots 
, you can factor the expression as 
In this case, the solutions are 
, which yields the factorization
Exercise 4:
When you multiply two powers of the same base, you add the exponents:
So, in your case, you have
Answer:
No
Step-by-step explanation:
she should have just factored x² - 6x - 7 = 0
(x + 1)(x - 7) = 0
x = -1, x = 7
"For what value of x does g(x) = 0"
g(x) = y
This is asking:
when y = 0, what is the value of x?
Or you can see it as (?, 0)
6 is the value of x
Answer:
16 hours i think or 8 rip
Step-by-step explanation:
10 + 24 divided by 276
The average speed is obtained by finding the slope of the function in the given interval:
Substituting values we have:
Rewriting:
Then, the generic equation of the line is:
Where,
v: average speed (slope of the line)
(t0, n0): ordered pair that belongs to the line.
Substituting values we have:
Answer:
the average speed of the car is:
b. 0.75
an equation of the line is:
b. n-6= 0.75(t-8)
