A perpendicular line has an opposite reciprocal slope. This means that the new line will have a slope of -4/3x. Plug in x and y into the equation y=Mx +b where m is the slope (-4/3):
-3=(-3/4)(-3) + b
and isolate b:
b-3=(-3/4)(-3)
b=(-3/4)(-3) +3
b=9/4+3
b=21/4
The final equation is y= -4/3x + 21/4
The y intercept is (21/4).
Answer:
x = 5
Step-by-step explanation:
(10/3)/5 = (x+1)/9
(10/3)9 = 5(x+1)
90/3 = 5x + 5
30 = 5x + 5
25 = 5x
x = 5
<span>x^2 + 22x + 121 = 9 + 121 ..............a^2 + 2ab + b^2 = (a+b)^2
(x + 11)^2 = 130
answer
</span><span>you must add 121 to complete the square</span>
