Let no. of shirts be x.
Chris -- 7x
Brian --- 5x
132x/(7x+5x) = 11
x=11
Chris sold (11 x 7) shirts = 77 shirts
Brian sold (11 x 5) shirts = 55 shirts
Answer:
Step-by-step explanation:
A horizontal line is a "y = " line. So the horizontal line that goes through the point given has the equation y = -1 (-1 being the y coordinate of the point). That means that another point on this line, y = -1, will also have to have a y coordinate of -1. The only one is the last one, (-2, -1).
answer:
C. 16
explanation:
when x is 0, the y-intercept is 8
coordinates: (0,8) and (4,6)
slope:
equation:
[ where m is slope and b is y-intercept ]
solve for x-intercept:
note: zeros of a function are the values of x when f(x) is equal to 0
