In order to solve the following system of equations by addition, which of the
following could you do before adding the equations so that one variable will
be eliminated when you add them?
4x – 2y=7
3x – 3y=15

a. multiply the top equation by 3 and the bottom equation by 2

b. multiply the top equation by 3 and the bottom equation by 4

c. multiply the top equation by 1/3

d. multiply the top equation by
-3 and the bottom equation by 2

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )

The answer is 76° i believe

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
