1 solution is available when variable equals a constant.
Answer: Option B.
<u>Explanation:</u>
You will be able to determine if an equation has one solution (which is when one variable equals one number), or if it has no solution (the two sides of the equation are not equal to each other) or infinite solutions (the two sides of the equation are identical).
The ordered pair that is the solution of both equations is the solution of the system. A system of two linear equations can have one solution, an infinite number of solutions, or no solution. If a consistent system has exactly one solution, it is independent.
Answer:
Step-by-step explanation:
Weekly tax that Lisa pay is 5% of her weekly earning at $2.50
= 5/100× $2.50=$0.125
X^2+12x+6=0 subtract 6 from both sides...
x^2+12x=-6 halve linear coefficient, square it, and add it to both sides...
x^2+12x+36=30 now the left side is a perfect square...
(x+6)^2=30 take square root of both sides...
x+6=30^(1/2) subtract 6 from both sides...
x=-6-30^(1/2) and -6+30^(1/2)

Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The null hypothesis is 
The alternative hypothesis is 
The p-value is 
The level of significance is 
From the given values 
so we fail to reject the null hypothesis
So there is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 10%.
