Find the equation of the line that is perpendicular to 3x-4y=5
1 answer:
Answer:
4x + 3y = 0
Step-by-step explanation:
A line perpendicular to one written in standard form can be found by swapping the x- and y-coefficients and negating one of them. Usually, you want the leading (x) coefficient to be positive, so here we can negate that one. This process give ...
4x + 3y = 0
The constant on the right can be chosen to make the line go through a desired point. Here, no point is specified, so we have set it to zero.

Answer:
x = 1
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 5 when x = 3
k = yx = 5 × 3 = 15, thus
y = ← equation of variation
When y = 15 then
15 = ( multiply both sides by x )
15x = 15 ( divide both sides by 15 )
x = 1
