Answer:
C=12
Step-by-step explanation:
2x12=24
3x12=36
5x12=60
The lines y = 2x - 1 and y = -2x + 3 intersect at exactly one point which means this system has exactly one solution. so the system is consistent and independent
Answer:
x = 21
Step-by-step explanation:
4 - 7x +10 = 15 - 6x - 8
-7x + 14 = -6x -7
14 + 7 = -6x + 7x
21 = x or x=21
Answer:
-1/7
Step-by-step explanation:
m=y2-y1/x2-x1
m=4-5/2--5=-1/7
m=-1/7
Answer:
closed circle on -9 and shaded to the right
Step-by-step explanation:
Since it has "≥", the circle would be closed.
Now, it states that "x is greater than or equal to -9"
So that means x would be positive and would start at -9.
Since x is unknown, the line would extend to the right side(positive side).
