Find an equation of the the line satisfying the given conditions. through (7, 2); perpendicular to 4x + 9y = 46 9x - 4y = 1 • 9x - 4y = 55 4x - y = 55 9x + 4y = 55

  9x - 4y = 55

Step-by-step explanation:

The equation for the perpendicular line can be written by swapping the x- and y-coefficients and negating one of them. Usually we choose to negate the one that makes the x-coefficient positive. Here, that process gives ...

  9x - 4y = <some constant>

The value of the constant can be found by putting the (x, y) values of the given point into the left-side expression:

  9x - 4y = 9·7 -4·2 = 55

  9x - 47 = 55

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
