Answer:
x = 2
Step-by-step explanation:
<u>Step 1: Set 3x - 2 equal to 5x - 6 to get x</u>
3x - 2 = 5x - 6
<u>Step 2: Solve for x</u>
3x - 2 + 6 - 3x = 5x - 6 + 6 - 3x
4 / 2 = 2x / 2
2 = x
Answer: x = 2
Find the number of pieces that aren't red, by subtracting the red from the total:
11 - 5 = 6 are not red.
The probability is the number of none red, over the total number of pieces: 6/11
Answer:
g(f(x)) = -x^2 + 4
Step-by-step explanation:
What we simply have to do here is to put f(x) into g(x)
What this mean is that every x in g(x) will be represented by f(x)
Thus, we have it that
-x^2 - 1 + 5
= -x^2 + 4
We will have to use the distance formula in order to determine the lengths of each side of the triangle.
Distance formula:

Let's calculate AB first:
A (1, 7) and B (-2, 2)
A: x1 = 1 and y1 = 7
B: x2 = -2 and y2 = 2
so



AB =

or (rounded to the nearest tenth) ≈ 5.8
Now let's do BC:
B: x1 = -2 and y1 = 2
C: x2 = 4 and y2 = 2
So


BC =

or 6
Now let's do CA
C: x1 = 4 and y1 = 2
A: x2 = 1 and y2 = 7
So



CA =

or (rounded to the nearest tenth) ≈ 5.8
So let's recap:
AB ≈ 5.8
BC = 6
CA ≈ 5.8
So AB and AC are the same length while BC is .2 units longer which means this is an
isosceles triangle.
