The answer is 0 < x < infinity
Answer:
140/3 or 46.6(with the 6 repeating)
Step-by-step explanation:
(x+55)+(2x-15)=180
Answer:
-1/2
Step-by-step explanation:
The slope of a line is found by using
m = (y2-y1)/(x2-x1)
= (9-10)/(6-4)
= -1/2
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
