Mathematics
1 answer:
Lilit [14]2 years ago
3 0

Answer:

Step-by-step explanation:

The given quadratic must be rewritten in standard form before anything else is done:  -2x^2 + 8x - 8 = 0.  The coefficients of the x terms are {-2, 8, -8}.

The discriminant b^2 - 4ac is therefore (8)^2 - 4(-2)(-8), or  64 -  64, or 0.

A zero discriminant points to two real, equal solutions.

How do you do it tell me step it step please
Alborosie
The steps for dividing fractions are:
Keep
Flip
Change
As in, keep the first fraction the same (we can write 7 as 7/1 to make it a fraction), flip the second fraction upside down, and then change the division symbol to a multiplication symbol. This gives you:
7/1 × 5/6
And to multiply fractions, you multiply across, which means that you do (7 × 5 = 35)/(1 × 6 = 6). Your answer, therefore, is 35/6, or, as a mixed number, 5 5/6. I hope this helps!

If I paid 3.00 for 2 chocolate bars how much would i pay for 6,700?
Licemer1 [7]
First we need to find the cost per chocolate bar aka the unit rate per chocolate bar

We start by taking 3$ and dividing it by 2 which gives us a total of 1.50$ each per chocolate bar

Now that we know that our unit rate is 1.50$ per bar we then do 1.50$ times 6,700 which gives us a total of 10,050$

This means that our answer is 10,050$ meaning you paid 10,050$ for 6,700 chocolate bars
