It went from 10 to -2, so you need to find the difference. The way you'd do this is: 10 - (-2). Do you know how to subtract a negative number from a positive number?

A company sells widgets. The amount of profit, y, made by the company, is related to
Burka [1]

Answer:

$1954

Step-by-step explanation:

Given the profit function expressed as;

y=-3x^2 + 197x – 1279

The profit is at maximum when dy/dx = 0

dy/dx = -6x + 197

0 = -6x+197

6x = 197

x = 197/6

x = 32.83

substitute 32.83 into the modeled function

y=-3x^2 + 197x – 1279

y -3(32.83)²+197(32.83) - 1279

y = -3(1,078.03)+6,467.51 - 1279

y = -3,234.09+6,467.51-1279

y = 1,954.42

hence the maximum amount of profit the company can make, to the nearest dollar is $1954

What is 80% of _____ is 60
Shtirlitz [24]

Answer:

75

Step-by-step explanation:

First, we know that 60 is 80 percent of something.

So, on that knowledge, we can setup this equation:

X × 0.80 = 60

Then, we multiply both sides by 0.80 , we then get 75.

We can check with 75 × 0.80 does equal to 60!
