Answer:
- D) f(x) = (x - 1)(x - 2)(x - 3)
Step-by-step explanation:
<h3>Given </h3>
<h3>To find</h3>
- The function in factored form
According to graph we observe:
- the function has 3 roots at x = 1, 2, 3;
- the function is of odd degree;
- the function is increasing, so the coefficient is positive
This gives us the function:
- f(x) = (x - 1)(x - 2)(x - 3)
The matching answer choice is D
Answer:
ok hold on
Step-by-step explanation:
I think, i might not be right but I think it A
8 = 1. The relationship equation is y = x - 7
To calculate this we simply need to devide 153 by 18.
153/18=8.5
which means that Sarah can buy 8 new CDs and will have
153 - 8*18=9 dollars spare.
Sarah has extra cash because with that spare money she can't buy whole new CD.
Answer:
a) y = 
b) x = 4
Step-by-step explanation:
a) 
3y + 2 = 20y - 5
2 = 20y - 3y - 5
2 = 17y - 5
2 + 5 = 17y
7 = 17y
y =
b) x² + 5 = 21
x² = 21 - 5
x² = 16
x = √16
x = 4
