Answer:
$612
Step-by-step explanation:
2/13 of 3978 is 612
Answer:
The quadratic function is f(x) = a * x^2 + b * x + c . The b-value is the middle number, the number next to the x. The other letters, a and c, are also numbers like b.
You should subtract 5 from both sides next.
Adding 2x to both side will give you the following.
5 + 5x = 9
And since you got all the variable terms to the left, you want all the constant terms to the right. You do that by subtracting 5 from both sides. This gives you the below statement.
5x = 4
You can then divide to solve.
x = 4/5 or .8
The answer is 625. Hope this helps.
