1 answer:
tester [92]2 years ago

Answer: B

Step-by-step explanation:

The equation y+2=\frac{3}{4} x-8 is not yet in slope-intercept form(y=mx+b).  Simply subtract 2 from both sides to turn the equation into slope intercept form as y=\frac{3}{4}x-10.  For a line to be perpendicular to another, it must have an opposite reciprocal slope.  A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa.  Thus, 3/4 would become 4/3.  The opposite reciprocal of 3/4 would be -4/3.

The slope of the line given is 3/4.  Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: y=-\frac{4}{3} x+b.  Then, because the line passes through -12, 1, plug those values in for x and y, respectively.  

1=-\frac{4}{3}*-12+b

1=16+b

-15=b

Thus, the equation of the line is y=-\frac{4}{3} x-15, or B.

Hope it helps :D

What value should be added to the expression to create a perfect square? x^2 - 20x
boyakko [2]
To complete the square:
we take the coefficient ox "x" (which in this problem is -20)
we divide it by 2
square that number
then add it to both sides of the equation

-20 / 2 = -10
-10^2 = 100
then we add 100 to both sides of the equation:
x^2 -20x
x^2 -20x +100 = 100
******************************************************
To get the roots of the equation, we take the square root of both sides:
(x -10) * (x-10) = 10
(x-10) = square root (10)
x-10 = <span> <span> <span> 3.1622776602 </span> </span> </span>
x1 = <span> <span> <span> 13.1622776602 </span>
