How can I solve -4x+y=29

vlada-n [284]

Answer:

Step-by-step explanation:

What variable are you solving for?

-4x+y=29

y=29-(-4x)

y=29+4x

y=4x+29

----------------

-4x=29-y

-4x=-y+29

x=1/4y+29/-4

y=1/4y-29/4

A hyperbola centered at the origin has a vertex at (0,−40) and a focus at (0, 41).

aniked [119]

$\frac{(x-h)^{2} }{a^{2} } - \frac{(y - k)^{2} }{b^{2} } = 1$

$\frac{(x-0)^{2} }{40^{2} } - \frac{(y - 0)^{2} }{b^{2} } = 1$

a² + b² = c²

40² + b² = 41²

b² = 41² - 40²

b² = 1681 - 1600

b² = 81

b = 9

slope (m) of asymptote = $+/-\frac{y}{x} = +/-\frac{b}{a} = +/-\frac{9}{40}$

y-intercept (b) = 0 since the center is at the origin

Answer: y = $\frac{9}{40}x$ and y = $-\frac{9}{40}x$
