Answer:

b = (T - a - c - d) / 3
Step-by-step explanation:
Let T be the total number of points required to advance.
a, c and d are points scored in the local matches, and b is the number of points scored in the district match. If b is worth 3 times as much as the other matches, the total number of points is given by:

Isolate b in order to find out how many points they need in the district match:

They need to score (T - a - c - d)/3, in the district match in order to win.
The new slope is 3, but the y-intercept doesn't change.
Answer:
A slope of the line over the interval of [-6, -1] is ⅕ as illustrated in the graph above
Answer:

Step-by-step explanation:

Adding both equations will make it:

Putting x = 10 will make it:

= 3(1000)-40+1
= 3000-39
= 2961
Answer:
14
Step-by-step explanation:
the four smaller rectangles of each of the corners: 2*1=2. since there are four of them, 2*4=8
the middle, larger rectangle: (6-2-2)*(1+1+1) = 2*3 =6
add small and big rectangles: 8+6 = 14
