Consider the line through (-1, -4) and (1, 2). What is the slope (m) of the line?

zloy xaker [14]

Answer:

3

Explanation:

$\bold{\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(-1,\:-4\right),\:\left(x_2,\:y_2\right)=\left(1,\:2\right)}$

$\bold{m=\frac{2-\left(-4\right)}{1-\left(-1\right)}}$

Find the nonpermissible replacement for y in the expression n^2/2n+8

ANEK [815]

Answer:

The nonpermissible replacement of the variable n is -4

Step-by-step explanation:

The nonpermissible replacement of the variable in a certain expression is the value of the variable that will make the denominator of the expression zero.

The expression $\dfrac{n^2}{2n+8}$ has the denominator $2n+8.$

This denominator cannot be equal zero, thus,

$2n+8\neq 0,\\ \\n\neq -4$ .

I need help with know number 5 and 6 can anyone help me

laiz [17]

I'm not going to give you the answer, but I can try to help you. A common denominator, I think, is like when you try to find out the number they all multiply. Like, for example, 9. 1, 3, 9, etc. are numbers you can use to either multiply up to 9, or more than 9. I don't know if I even make sense. Just do a good amount of research.
