Answer:

288

Step-by-step explanation:

We want to evaluate the expression:

- 3a(2b - 4c)

For

a =  - 3 \\ b = 2 \\ c =  - 7

We substitute the given values into the expression to get:

- 3( - 3)(2 \times 2 - 4 \times  - 7)

This gives us:

9(4  + 28)

Evaluate the parenthesis:

9(32)

= 288

On a separate piece of graph paper, graph y = -|x| + 1; then click on the graph until the correct one appears.
a_sh-v [17]
|x| is tricky but maybe I can tell you so that it's clear 4ever.

You have to look at when what's inside the absolute value iszero. In this case x=0. That easy. Then, you have to split the cases:

For x>= 0, you have y = -x+1,

For x<=0, you have y = -(-x) + 1 = x+1, because abs(x)=-x, if x<=0.

Notice that x=0 is included in either case, because |x| is continuous.

Then plot each line choosing a couple of points, notice that for one case you should choose x=-1, -2, or x=0, but not positive values, and the other way for the case with x>=0.

Well, if there are 12 eggs grouped together, and 5 of them hatch to be snakes.... More than likely the other 7 will also turn out to be snakes because the eggs are all grouped together.
