Find the zeros of the function.
Enter the solutions from least to greatest.
f(x) = 8x2 – 800

-10, 10

Step-by-step explanation:

To do that, we can set up an equation:

We can divide both sides by 8 to make it easier to solve:

Now, isolate the x and take the square root of both sides:

Therefore, the 2 zeroes of f(x) are -10 and 10.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
