Along the x-axis is the number of songs purchased. Along the y-axis is the amount of money left.
We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
Answer:
x=-3
Step-by-step explanation:
Answer:
y=3(X-1)2-2y=3(X-1)2-2
Usa la forma de vértice ,y=un(X-h)2+ky=un(X-h)2+k, para determinar los valores de unun, hhy kk.
un=3un=3
h=1h=1
k=-2k=-2
Encuentra el vértice (h,k)(h,k).
(1,-2)(1,-2)

3 all you have to do is divide 7 by seven and get 1 and after subtract 4 by 1 and you get 3.
