3x-8 = 8x+4
subtract 3x from each side
-8 = 5x+4
subtract 4 from each side
-12 = 5x
divide -12 by 5 to get x
x = -12/5 = -2.4
Make more than a 80 on quizzes and you should be fine 75 lowest possible
All the other stuff, east/west, doesn't matter.
He drives 3 miles north, then later on he drives 4 more miles north:
3 + 4 = 7
The dog show is 7 miles north of his home.
Answer:
y = 250 + 15x
Step-by-step explanation:
Use slope intercept form for equation, which is y = mx +b. m is slope and b is the y-intercept.
Find slope by change in y over change in x. So pick two points, for example (0, 24) and (2, 20). Slope (m) will be
(y2-y1)/(x2-x1)
= (24-20)/(0-2)
= 4/-2
m = -2
Y-intercept is 24.
Equation is y = -2x + 24
