X=-1
Step-by-step explanation:
3x-6=-9
3x=-9+6
3x=-3
x=-1
Answer:
b = 80
Step-by-step explanation:
Given that,
x² + bx - 81
To find,
value of b
What is factorable?
A polynomial equation with highest degree 2 is if factorable when
- we can find two terms which when multiples = -81x², <em> ( x² * - 81 = -81x² ) </em>
- and when add = bx
possible factors:
- -1x * 81x = -81x² (Accepted)
- 1x * -81x= -81x² (rejected)
- 9x * -9x = -81x² (rejected)
- -9x * 9x = -81x² (rejected)
Only when -1x , 81x is added -1x + 81x = 80x
so, bx = 80x
b = 80
<h3>The equation is x² + 80x - 81</h3>
Okay so this is your equation; 17=221/x
all you need to do is multiply 221 by 17 and you'll have your answer. I hope this helps!
Jaymie will measure the segment and then place the point just across from the line's beginning point to create a congruent segment that shows the similarity between them.
<h3>What are the conditions of the congruent triangle?</h3>
Triangles that are equivalent in terms of size and form are known as a congruent triangle.
Segments will be built using the straightedge, and measurements will be taken using the compass. They will pick a starting point and draw a line using the straightedge, then use the compass to finish the job.
To make the congruent segment, Jaymie will measure the segment and then position the point that is opposite from the line's starting point.
Jaymie, on the other hand, will have to work a bit harder with the compass since she will need to draw a semi-circle in the original angle and transfer this measurement to the new line in order to create congruent angles.
