Write the equation of a line through the point (7,-10) and
perpendicular to 5y + 3x = 15.

Step-by-step explanation:

In order to find the equation I used the following formula:

y - y1 = m ( x - x1)

P.s y1 & x1 are the coordinates of the given point

ab will be equal to

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
