Write an equation in slope intercept form for the line that passes through (-20,-6) with slope m=1/4
brilliants [131]
We start with the equation y-y1 =m (x-x1) because we have m the slope = 1/4 and a point on the line with the coordinates (x1=-20, y1=-6) so, 
 
y+6=1/4 ( x+20); 
y=(1/4)x + 20/4 -6; 

y= (1/4)x -1 and this is the equation in slope intercept form y=mx +b  where the lope m= 1/4 and b= -1 the y-intercept

Answer <span>y= (1/4)x -1 </span>

Part A: Solve A = (x + 23) for x. (4 points) Part B: Determine the value of x when A = 108. (2 points) Part C: Solve -np - 90 &g
Galina-37 [17]
<span>Part A: Solve A = (x + 23) for x.

A = x + 23

=> A - 23 = x + 23 - 23

=> A - 23 = x

=> x = A - 23 <------- answer

Part B: Determine the value of x when A = 108

Replace the value of A in the expression x = A - 23

x = 108 - 23 = 75

x = 75 <------- answer

Part C: Solve -np - 90 > 30 for n.

-np - 90 > 30

=> -np + np - 90 >30 +  np

=> - 90 > 30 + np

=> -90 - 30 > 30 - 30 + np

=> -120 > np

=> np < - 120 <----- answer
