Answer:
x ≤ 30
Step-by-step explanation:
'at most' means the same as 'less than or equal to'.
The sign 'for less than or equal' to is ≤.
So it's simply x ≤ 30.
1. A
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.
You'd move the decimal to the right twice so 0.0514 as a percentage is <span>5.14%</span>
Answer:
c
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and
b is the y-intercept.
y=mx+b
m=−3
b=0
y=-3x+0
Answer:
1. 54ft^2 2. 48ft^2
Step-by-step explanation:
1. A=1/2h(a+b)
A= 1/2x6(10+8)
A=54
2. A=1/2x6(12+4
A=48
