Step-by-step explanation:
rule for line c: y=x+3
x y
0 3
1 4
2 5
3 6
I was able to determine the rule because line c has a slope (m) of 1 (it goes up one and sideways one each time). Its y int. is at 3, so that means 3 is b in the equation y= mx+b
Rule for line D: y=1/2x
x y
0 0
2 1
4 2
6 3
Line d is y=1/2x becaise it goes up 1 and then sidewys 2, so slope (m)= 1/2. There is no b becase it crosses the origin.
(-2,-1) (-4,-2) (-6, -3) just extend the line with a ruler.
hope this helps! :)

Answer:
6
Step-by-step explanation:
Cost and revenue are equal when ...
C = R
2.5x +21 = 6x
21 = 3.5x . . . . . . subtract 2.5x
6 = x . . . . . . . . . .divide by 3.5
The company must sell 6 items to break even.
Answer:
d, c, a, b
d= 32, 56
c = 34, 64
a = 85, 92
b = 23, 55
Step-by-step explanation:
Answer:
From the given, we establish this relationship:
RS + ST = RT
RS = ST since S is the midpoint of RT
Thus, let's use RS = ST to find x,
By substituting the given expressions:
RS = ST
8x + 11 = 14x - 1
12 = 6x
x = 12/6
thus,
x = 2
