First option:
y=money saved
x=number of months
y=30x+500
Second option:
y=50x+200
We have this system of equations:
y=30x+500
y=50x+200
We can solve this system of equations by equalization method
30x+500=50x+200
30x-50x=200-500
-20x=-300
x=-300/-20
x=15
so;
y=30x+500
y=30(15)+500
y=450+500
y=950
Answer; after 15 months, she would save the same amount using either option, the amount saved in either option will be $950.
For the 11 the first one is x = 4y and for the 2 one it will be x=−6−2y
Answer:
(X<-25) or -oo, -25
Step-by-step explanation:
because max is -25
Moving 4 units to the left would change from y=x^2 to y=(x+4)^2.
