Answer:
y = -5
Step-by-step explanation:
y = x / 2
For x = -10
Plug -10 into the equation
y = -10/2
y = -5
------------------
For the remaining values
x y
0 0
4 2
10 5
Algebra is solving for the unknown so
if you have 10 apples and you give 5 to your friend, how many apples would you have so that is also 10-5=x solve for x
or it could be more complicated like (x-2)/6+4x-3=17
Answer:
Explained below.
Step-by-step explanation:
The human resource department at a certain company wants to conduct a survey regarding worker morale. The department has an alphabetical list of all 4,502 employees at the company and wants to conduct a systematic sample of size 50.
Systematic sampling is a kind of probability sampling method in which individuals from a larger population are nominated according to a random initial point and a static, periodic interval.
(a)
A sample of size 50.
Then the value of <em>k</em> will be: 
Thus, the value of <em>k</em> is 90.
(b)
Label the employees from 1 to 4502.
And select every 90th employee.
So, the individuals who will be administered the survey are:
90th, 180th, 270th,...
Answer:
x= -1/2 = -0.500
x=4
Step-by-step explanation:
2x^2-7x-4=0
2x^2-8x+1x-4=0
2x(x-4)+1(x-4)=0
(2x+1)(x-4)=0
2x+1=0...2x= -1.. x= -1/2 x-4=0 .. x=4
checking the solution
2(-1/2)^2-7(-1/2)=4..... 4=4
2(4)^2-7(4)=4....... 4=4
