Answer:
19/41
Step-by-step explanation:
this fraction cannot be simplified since 19 is a prime number.
You can solve this in two ways.
1. Graphical. Plot the graph for x between -5 and 1 (see attachement).
The vertex of the graph is the peak of the curve, which has the coordinates x=-2, y=-9.
2. Analytical. Calculate the derivative of the function f(x)

Solve the equation:

will give the solution x=-2.
Replace x=-2 in the f(x) function and you'll get the value of y:

You get the same answer: x=-2, y=-9
So the answer is

Answer:
4556.25
Step-by-step explanation:
10:5:8=x:y:18
18/8=2.25
x=2.25x10=22.5
y=2.25x5=11.25
11.25x22.5x18=4556.25
Answer:
$10.23
Step-by-step explanation:
$2.19+$1.39+$3.69+$2.29=9.56
9.56 x 1.07=10.2292
You round to the nearest tenths place
$10.23
120/100 = x/15
100x = 1800 (Divide by 100 on both sides)
x = 18
