Answer:
The input value is 3/4
Step-by-step explanation:
we know that
The input value that produces the same output value for the two linear functions, is the intersection point both graphs
we have
---> equation A
---> equation B
Equate equation A and equation B
solve for x
therefore
The input value is 3/4
To solve for any given number of variables, you need that number of equations to solve for all variables. When there are only two variables you only need to equations to solve for them both. You eliminate one variable at a time, order does not matter.
y-x=6 and y+x=-10
Since one equation has -x and the other +x, you can simply add the two equations together to eliminate x...
(y-x=6)+(y+x=-10)
y+y-x+x=6-10
2y=-4
y=-2, now you can use this value of y in either original equation to solve for x...
y-x=6, using y=-2 becomes:
-2-x=6
-x=8
x=-8
So the solution to the system of equations is the point (-8, -2)
You can always check by using these two values in the original equations...
y-x=6, -2--8=6, -2+8=6, 6=6
y+x=-10, -2+(-8)=-10, -2-8=-10, -10=-10
Complete Question
The complete question is shown on the first uploaded image
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The number of observation is greater than 50 i.e. n > 50
The level of significance is
Generally given that n > 30 then we will make use of the z table
So
From the z table the critical value corresponding to the level of significance level for a two-tailed test is
The answer is d 1 in = 4m
