What is the answer to this?
konstantin123 [22]

Answer:

\huge\boxed{-6}

Step-by-step explanation:

Since we know the values of a, b, and c, we can substitute them into our expression and get the value.

-2b + | -3c + a |\\\\-2(6) + |-3(-3) + -3 |

A negative multiplied by a negative gets us a positive.

-2(6) + |9 + -3 |

Adding a negative is the same as subtracting a positive.

-2(6) + |9  -3 |\\-2(6) + 6

-2 \cdot 6 = -12\\\\-12+6\\\\-6

Hope this helped!

Can someone please explain how to do these?
Pani-rosa [81]

Answer:

<u>First question answer:</u> The limit is 69

<u>Second question answer:</u> The limit is 5


Step-by-step explanation:

For the first limit, plug in x=8 in the expression (9x-3), that's the answer for linear equations and limits.

So we have:

9x-3\\9(8)-3\\72-3\\69

The answer is 69


For the second limit, if we do same thing as the first, we will get division by 0. Also indeterminate form, 0 divided by 0. Thus we would think that the limit does not exist. But if we do some algebra, we can easily simplify it and thus plug in the value x=1 into the simplified expression to get the correct answer. Shown below:

\frac{x^2+8x-9}{x^2-1}\\\frac{(x+9)(x-1)}{(x-1)(x+1)}\\\frac{x+9}{x+1}

<em>Now putting 1 in x gives us the limit:</em>

\frac{x+9}{x+1}\\\frac{1+9}{1+1}=\frac{10}{2}=5

So the answer is 5
