b must be equal to -6 for infinitely many solutions for system of equations 
and 
<u>Solution:
</u>
Need to calculate value of b so that given system of equations have an infinite number of solutions
Let us bring the equations in same form for sake of simplicity in comparison
Now we have two equations
Let us first see what is requirement for system of equations have an infinite number of solutions
If 
and 
are two equation
then the given system of equation has no infinitely many solutions.
In our case,
As for infinitely many solutions 
Hence b must be equal to -6 for infinitely many solutions for system of equations and
4*4-5*3-2x+6= -x-7/2 slope = 2
3 * 3 - 4 *2 -2x +1= - x - 2/2 slope = -2
2 + -2 = 0
Answer:
<em>12</em>
Step-by-step explanation:
<em>1/4= 3/12</em>
<em>5/6=10/12</em>
<em>So they both have a common denominator of 12!</em>
Hope this helps, have a good day. c;
Answer:
3872/(x^2 - 2)
Step-by-step explanation:
Simplify the following:
(16^3 - 3^2 - 5×43)/(x^2 - 2)
3^2 = 9:
(16^3 - 9 - 5×43)/(x^2 - 2)
16^3 = 16×16^2:
(16×16^2 - 9 - 5×43)/(x^2 - 2)
| 1 | 6
× | 1 | 6
| 9 | 6
1 | 6 | 0
2 | 5 | 6:
(16×256 - 9 - 5×43)/(x^2 - 2)
16×256 = 4096:
(4096 - 9 - 5×43)/(x^2 - 2)
43 (-5) = -215:
(4096 - 9 + -215)/(x^2 - 2)
4096 - 9 - 215 = 3872:
Answer: 3872/(x^2 - 2)
