Answer:
f(2) = 16
Step-by-step explanation:
f(2) = 3(2)2+4
f(2) = 6*2 = 12 +4
f(2) = 16
Given:
Fixed salary = $1400
Additional salary = $500 each time he sells a car.
To find:
The equation for the situation and how much money he will make if he sells 7 cars.
Solution:
Let y be the total salary of the salesman after selling x cars.
He will earn an extra $500 each time he sells a car. So, extra money earned by him after selling x cars is 500x.
Total salary = Fixed salary + Additional salary

Substituting
, we get



Therefore, the required equation for the given situation is
and the salesman will earn $4900 if he sells 7 cars.
Answer:
5.86
Step-by-step explanation:
Answer:
The two equations are not equivalent and no property is used.
Step-by-step explanation:
54 - (30 - 8) ... (i)
(54 - 30) - 8 ... (ii)
Solving (i) and applying PEMDAS:
We open the brackets first;
54 - 30 + 8 = 54 + 8 - 30 = 32
Solving (ii) and applying PEMDAS:
We open the brackets first;
54 - 30 = 24
24 - 8 = 16
Answer:
x = 1/2
Step-by-step explanation:
First, let's put the statement into words:
6 * x^2 + 5x = 4
Now, we can see which values work in this equation.
-4/3 doesn't work
1/2 works!
-3/4 doesn't work
2 doesn't work.
