Subtract 8d from both sides
21 = 12d + 5 - 8d
Simplify 12d + 5 - 8d to 4d + 5
21 = 4d + 5
Subtract 5 from both sides
21 - 5 = 4d
Simplify 21 - 5 to 16
16 = 4d
Divide both side by 4
16/4 = d
Simplify 16/4 to 4
4 = d
Switch sides
d = 4
<u>Check answer</u>
8d + 21 =12d + 5
Let d = 4
8 × 4 + 21 = 12 × 4 + 5
Simplify 8 × 4 to 32
32 + 21 = 12 × 4 + 5
Simplify 12 × 4 to 48
32 + 21 = 48 + 5
Simplify 32 + 21 to 53
53 = 48 + 5
Simplify 48 + 5 to 53
53 = 53
Answer:
y=-5x+1 (without point p)
Step-by-step explanation:
Identify the slope of y= -1/5x+2:
m=1/5
*The perpendicular slope is the negative reciprocal of the given slope, in this case 1/5 is that given slope.*
So, the slope of the line perpendicular would be:
mp(slope perpendicular)= -5
Then you construct the line equation with just a general b in this case which gives you the equation:
y= -5x+1
The equation is then put into standard form to find the equation for point p (not positive if this what was meant by the question if so this'll give you the correct answer) ax+by=c :
