What is an equation in point-slope form for the line perpendicular to y=3x+9 that contains (-6,5)?

1 answer:

4 0

To be perpendicular, the slope of the new line has to have the reciprocal of the original slope.

Do this by flipping the slope (ifi t's a whole number make it a fraction) and change the sign.

3 ⇒ -1/3

Input x and y and solve for b.

5 = -1/3(-6) + b
Simplify.
5 = 2 + b
Subtract 2 from both sides.
3 = b

y = -1/3x + 3

Answer:

$11 \frac{1}{4}$ = $\frac{45}{4}$ = $11.25$

Step-by-step explanation:

Hi!

Next time, I'd recommend just typing in the number, this is a bit hard to see.

To the point!

11 $\frac{1}{4}$ is equivalent to $\frac{45}{4}$ and in decimal form is 11.25.

Hope this helps!

3000 tickets, 3 prizes

1/3000 * 35,000 = $11.67 gain
1/3000 * 900 = $0.30 gain
1/3000 * 600 = $0.20 gain

Cost $18

$11.67 + 0.30 + 0.2 - 18 = - 5.83

Prove cosxtanx = sinx

finlep [7]

Cos(x)tan(x)

Transform the expression by using the formula for tan theta:
tan(t)= sin(t)/cos(t)

cos(x)= sin(x)/cos(x)

Cancel out the cos(x) since it’s on both sides

Final answer : sin(x)

cos(x)tan(x) is equal to sin(x)
