Answer:
Step-by-step explanation:
                                                                                                                         thomas age is 47
 
        
                    
             
        
        
        
1. Start with y=sx+m and input the slope of the line given, because the two lines are parallel they have the same slope. Then input the X and Y coordinates of point X to get 10=-1/2-5+m and finally solve the equation to get m=-7.5 or -15/2 making slope intercept form Y=-1/2-5-15/2 
2. Follow the same instructions imputing 1/2 in as the slope because it is perpendicular to the line. so you get 10=1/2-5+m. solve to get m=7.5 or 15/2 making the final equation Y=1/2X+15/2
        
                    
             
        
        
        
Answer: C
Step-by-step explanation:
We can use the expanding rule to get that one if the expressions is 
(9x^2 + 2x - 7)x + (9x^2 + 2x - 7)(-4)
 
        
             
        
        
        
I need -487 time to regroup.
i did 426 - 913 = -487
        
             
        
        
        
That's OK, but you have not said which variable you want to solve it for.
<u>To solve for 'x':</u>
                                           <span>c + ax = dx
Subtract c from each side:    ax = dx - c
Subtract  dx  from each side:   ax - dx = -c
Factor the left side:                 x (a - d) = -c
Divide each side by (a - d) :      x = -c / (a - d)  or  <u>x = c / (d - a)</u> .
