Y= -2x-6
2x+y=5 so then y= -2x+5

If you look at those two equations and ask yourself when is
y = a number-6 and in the same time
y = same number +5
The answer is never, so the system of equations has no solutions

Pls help I will mark brainlyesd

First, we have to solve for x by isolating it on one side.
6x + 10 = -8
(Subtract 10 from both sides)
6x = -18
(Divide both sides by 6)
x = -3

On option C, x is on -3, so that would be the correct answer

Excel - How to graph different APRs using one formula for an excel beginner? Image Attached

Levart [38]

Answer:

Please see the attachments. For reasons I cannot fathom, the Brainly censor seems to think there are unapproved words contained in this text, so I cannot post it as text. Among other things, that means you probably will not be able to copy and paste the formulas into your spreadsheet—you will have to type them.

I apologize if you are offended by any of the words contained in this answer. I hope you will take them in the intended context—a math problem about the use of Excel.

The U.S. RDA for protein for a girl is 46 g. If a piece of friedchicken contains 23 g, how many pieces would the girl have to ea

Nataliya [291]

The U.S RDA for protein is 46g for girl

If a piece of fried chicken contains 23g

To find the pieces of chicken she is to eat to satisfy the U.S RDA requirement,

The number of pieces of chicken is

$\text{Number of pieces}=\frac{U.S.\text{ RDA g protein required for a girl}}{g\text{ of protein in a piece of chicken}}$

The number of pieces of chicken is

$\begin{gathered} \text{Number of pieces of chicken}=\frac{46}{23}=2\text{ pieces of chicken} \\ \text{Number of pieces of chicken}=2\text{ pieces of chicken} \end{gathered}$

Hence, the right option is B
