a line is perpendicular to y - 5 = -1/4(x + 8) and goes through the point (-1,2). What is the lines y-intercept?
lisabon 2012 [21]

Answer:

y = 4x + 6

Step-by-step explanation:

Turn the equation we are given into slope-intercept form.

y - 5 = -1/4(x + 8)

y - 5 = -1/4x - 2

y = -1/4x + 3

The slope of a perpendicular line is the opposite reciprocal of the original line.

-1/4 -> 4/1 -> 4

Find the new y-intercept using the point given.

y = 4x + b

2 = 4(-1) + b

2 = -4 + b

6 = b

Fill in everything we solved for.

y = 4x + 6

Best of Luck!

How can I find the volume of a cone 9 radius and 18 height​
Anastasy [175]

Answer:

V = 486\pi, or approx. 1,526.814

Step-by-step explanation:

V = \pi*r²*(h/3)

plug in the numbers: V = \pi * (9)² * (18/3)

simplify: V = \pi * 81 * 6

simplify: V = 486\pi, or approx. 1,526.814

Evaluate x^-2 for x = -3.
Hitman42 [59]

Hey there!

If x = -3 then replace "x" with -3

New equation: -3^-2

(-1 × 3)^-2

(-1 / 3 )× 3

3 × 3 = 3^3 = 9 (Solving for your denominator)

(-1/3)^2

= (1/9)

This your answer is: 1/9

Good luck on your assignment and enjoy your day!
