You are at a football game. You decide to buy a hamburger for each of your 1 point 5 friends at the game. You also bought a soda for yourself for $4. You spent
a total of $21.50. How much do the hamburgers cost? WHICH EQUATION
FITS THIS SCENARIO?
4x + 5 = 21.50
21.50x + 5 = 4
5x - 4 = 21.50
5x + 4 = 21.50

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer:

c) the x-coordinate of the center of the circle increases by 3

step-by-step explanation:
