At the beginning of the year, Jeremiah had $30 in savings and saved an additional $10 each week thereafter. Brody started the year with $80 and saved $5 every week. Let JJ represent the amount of money Jeremiah has saved tt weeks after the beginning of the year and let BB represent the amount of money Brody has saved tt weeks after the beginning of the year. Graph each function and determine the number of weeks after the beginning of the year until Jeremiah and Brody have the same amount of money saved.

histogram or dot plot?

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
