5 0

The answer is -8.4 because you need to do order of operations.
First you need to divide -10.8 and 0.6 and you get -18
Then you have to add -10.8 and 9.6 and you get -8.4
So the answer is -8.4

Evaluate: f(x) = 2x^2 + 6x - 4; f(-5) *

BabaBlast [244]

$f(x)=2x^2+6x-4$

Find the f(-5) by substituting x = -5 in the equation.

$f(-5)=2(-5)^2+6(-5)-4\\f(-5)=2(25)-30-4\\f(-5)=50-34\\f(-5)=16$

Therefore, the answer is f(-5) = 16.

What is the approximate percent decrease when a fish count goes down from 850 to 500?

Fudgin [204]

So, the count went down from 850 to 500, or 350 units.

if we take the 850 to be the 100%, what is 350 in percentage off of it?

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
850&100\\
350&x
\end{array} \implies \cfrac{850}{350}=\cfrac{100}{x}$

solve for "x".
