Answer:
x<-1 or x>=5
Step-by-step explanation:
there is an open circle at -1
an open circle means it is not equal to
the line goes to the left which means x is less than
x < -1
there is a closed circle at 5
a closed circle means equal to
the line goes to the right which means x is greater than
x>= 5
the line looks like boat oars
so this is a compound inequality using or
x<-1 or x>=5
Answer to the expression : -9n - 54
Answer:
six plus x.
Step-by-step explanation:
there will be one solution because the lines intersect at exactly one set of points.
(0,6)(6,3)
slope(m) = (3-6) / (6-0) = -3/6 = -1/2
y = mx + b
6 = -1/2(0) + b
6 = b
y = -1/2x + 6
(0,0)(6,6)
slope(m) = (6-0) / (6-0) = 6/6 = 1
y = mx + b
6 = 1(6) + b
6 = 6 + b
6 - 6 = b
0 = b
y = x + 0
x = -1/2x + 6
1/2x + x = 6
1/2x + 2/2x = 6
3/2x = 6
x = 6/(3/2)
x = 6 * 2/3
x = 12/3 = 4
<span>solution is : (4,4)</span>
the answer is x is greater then -7
to find this add 4 to each side
then divide by -2.
since you divided both sides by a negative the symbol flips and you get x is greater then -7
