Answer:
x=10
Step-by-step explanation:
Add 6x to both sides.
−4x+5=−35
 Subtract 5 from both sides.
−4x=−40  
 Divide both sides by -4.

x=10

If  , then
, then  and
 and  because
 because  lies in the fourth quadrant.
 lies in the fourth quadrant.
By DeMoivre's theorem,

so the answer is B.

Answer:
   slope: 0.10
Step-by-step explanation:
The independent variable is the number of texts, so that goes in the denominator of the slope ratio.
   slope = (change in cost)/(change in texts)
   = ($30 -25)/(100 -50)
   = $5.00/50
   slope = $0.10 per text
 
        
             
        
        
        
For first question, What is approximate value of "......" this part is missing so please write whose approximate value question is asking to find
For second question we have to find 
In right triangle ABC as show in attachment, 
 ----(1)
----(1)
Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So 
Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So 
Plug these values in equation (1)

 To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown

Now 2 in top and bottom cancels out so we are left with

so thats the final answer for
