Find the distance from point (-1, 3) to the line 5 x - 4 y = 10.

Answers

Answer:

The answer is (27sqrt41)/41 on Odessyware

Step-by-step explanation:

We could use the formula, derive the formula, or just work it out for this case. Let's do the latter.

The distance of a point to a line is the length of the perpendicular from the line to the point.

So we need the perpendicular to 5x-4y=10 through (-1,3). To get the perpendicular family we swap x and y coefficients, negating one. We get the constant straightforwardly from the point we're going through:

4x + 5y = 4(-1)+5(3) = 11

Those lines meet at the foot of the perpendicular, which is what we're after.

4x + 5y = 11

5 x - 4y = 10

We eliminate y by multiplying the first by four, the second by five and adding.

16x + 20y = 44

25x - 20y = 50

41x = 94

x = 94/41

y = (11 - 4x)/5 = 15/41

We want the distance from (-1,3) to (94/41,15/41)

$d = √( (-1 - 94/41)^2 + (3 - 15/41)^2 ) = (27)/(√(41))$

what is x??

Answers

Hi there!

Answer:

x=-1

Step-by-step explanation:

Distributive property: ⇒ a(b+c)=ab+ac

5x-2=-7

add 2 both sides of an equation.

5x-2+-7+2

simplify.

5x=-5

divide by 5 both sides of an equation.

5x/5=-5/5

simplify

-5/5=-1

x=-1

Hope this helps!
