Answer:
1
Step-by-step explanation:
y- intercept occurs at x= 0. Thus, the y-intercept of a line can be found by substituting x= 0 into it's equation.
x -y= -1
When x= 0,
0 -y= -1
-y= -1
Divide both sides by -1:
y= -1 ÷(-1)
y= 1
Thus, the y-intercept is 1.
Answer:
x=-6 is an extraneous solution
Step-by-step explanation:
we have

squared both sides



solve the quadratic equation by graphing
The solution is x=-6 and x=-1
see the attached figure
<u><em>Verify each solution</em></u>
substitute the value of x in the original expression
For x=-6


----> is not true
so
Is an extraneous solution
For x=-1


----> is true
so
Is the solution

Answer:
6.8%
Step-by-step explanation:
the question has no information about class size (no. of student in class)
assume no. of student is infinite
P(3brown out of 6) = 6C3 * P(brown)^3 * P(not brown)^3
= 20 * 0.004913 * 0.695789
= 0.06837
