250 - 5(x) = 50
250 (-250) - 5x = 50 (-250)
-5x = -200
-5x/-5 = -200/-5
x = 40

Answer:

Step-by-step explanation:
When working with surds we need to take note of the roots present there.
To expand this equation we can do it the following way noting that √3 X √3 = 3
<em></em>
<em>Expanding (1-√3)(⅓+√3)</em>
1 X 1/3 = 1/3
1 X √3 = √3
-√3 X 1/3 =-√3/3
√3 X √3 = 3
hence, expanding the equation, we have
1/3 + √3 -√3/3 + 3
We can simply group the like terms and add them up.
[1/3 +3] +[√3-√3/3]
10/3 + 
= 
Answer:
profit=20%
Step-by-step explanation:
profit%=sp-cp/cp×100%
=1500-1250/1250×100
=250/1250×100
=20%
Answer:
The y-intercept is the point (0,-8)
see the attached figure
Step-by-step explanation:
we have

we know that
The y-intercept is the value of the function f(x) when the value of x is equal to zero
so
For x=0

therefore
The y-intercept is the point (0,-8)
