I need help please ASAP

 y = 2x + 14   x is the number of weeks. 14 (b) was his original performance in miles jogged per week. y is the expected performance.

Sketch attached.

Step-by-step explanation:  Given John's current performance, it is likely that he was able to jog some number of miles per week, the "b" in slope-intercept form.  To calculate:

30 = 2(8) + b

30 = 16 + b

30 - 16 = b

14 = b

Substitute into the slope intercept equation:

y = 2x + b

i dont know men

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
