In this case the two equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution to the system of equations<span>.</span>
Answer:
Step-by-step explanation:
y=kx
4=k(-2)
k=-2
y=-2x
when x=30
y=-2*30=-60
Answer: 13 is c im pretty sure and 14 is a im think hope fully it helps
Step-by-step explanation:
Answer:
x=9
Step-by-step explanation:
8(2x-6)=96
2x-6=96/8
2x-6=12
2x=12+6
2x=18
x=18/2
x=9
Answer:
EH = 120 degrees
Step-by-step explanation:
angles in a circle add up to 360 degrees
arc EF + arc FG + arc GH + arch EH = 360
95 + 90 + 55 + EH = 360
240 + EH = 360
subtract 240 from both sides to isolate EH
EH = 120 degrees
