Step-by-step explanation:
given :
2x - 3y = 11
-6x + 8y = 34
find : the solutions of the system by using Cramers Rule.
solutions:
in the matrix 2x2 form =>
[ 2 -3] [x] [11]
=
[-6 8] [ y] [34]
D =
| 2 -3 |
|-6 8 |
= 8×2 - (-3) (-6)
= 16-18 = -2
Dx = | 11 -3 |
| 34 8 |
= 11×8 - (-3) (34)
= 88 + 102
= 190
Dy = | 2 11 |
|-6 34 |
= 2×34 - (-6) (11)
= 68 + 66
= 134
x = Dx/D = 190/-2 = -95
y = Dy/D = 134/-2 = -67
the solutions = {-95, -67}
None of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.
<h3>Properties of an Isosceles Triangle</h3>
- An isosceles triangle has two base angles having equal angle measure.
- The side lengths that are opposite each of the equal base angles are also congruent to each other.
Thus, none of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.

Answer:
Step-by-step explanation:
the missing degree is a multiple of 360, so 0.
graph is like squiggly touching -1 at pi and touching 1 at 2 pi and so forth
Hello!
You can write down what the possible numbers their are
The numbers greater than 2 are 3, 4, 5, and 6
The numbers that are odd are 1, 3, and 5
List all the numbers out in a row
3, 4, 5, 6, 1, 3, 5,
Eliminate one of the numbers that repeat
3, 4, 5, 6, 1
You put the amount of answers of the total amount of outcomes
The answer is 5/6
Hope this helps!
The answer i pretty sure would be 3x
