Pl helppp I’ll give brainiest Find the equation of the line that is perpendicular to y = 2/3x - 5 and passes through
the point C (4,7).

y=-3/2x+13

Step-by-step explanation:

The slope of a perpendicular line is the negative inverse. The negative inverse of 2/3 is −3/2

That means the equation of the perpendicular line is y=−3/2x+a

To find a, you need to input the given values into the perpendicular line equation. When you do that, you get 7=-3/2(4)+a

When you solve for a, you get  a=13.

When you input that into the equation, you get a final equation of y=-3/2+13

Please mark as brainliest ;)

y = -3x/2 + 13

Step-by-step explanation:

to solve such kind of maths, follow this process:

find the slope/gradient:

y = 2/3x - 5

y = 2/3 ( x - 15/2 )

so we found our gradient is 2/3

if perpendicular,  m1 * m2  = -1

                             2/3 * m2 = -1

                             m2 = -3/2    this is our gradient is perpendicular

y - 7 = -3/2 (x - 4 )

y = -3x/2 + 6 + 7

y = -3x/2 + 13

Equation of the line is y = -3x/2 + 13

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
