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

Answer:
$28.68
Step-by-step explanation:
57.24+64.08
121.32
150-121.32
Answer:
0.49
Explanation:
Given the expression:
tan 26°
Evaluating using calculator
tan 26° = 0.4877
Hence the decimal rounded to the nearest hundredth is 0.49
We have to find what percent of the audience from the 16-25 age group gave the movie poor rating. There were 113 viewers from this group. There were 7 of them that gave the movie poor rating. We will use the proportion: 113 / 7 = 100% / x% . Then we will cross multiply: 113 x = 700; x = 700 : 113; x = 6.19%. Answer: A ) 6.19%.
