4x < -36
x < -9
=> No
B) -5/3x + 17/3 < 9
-5x + 17 < 27
-5x < 10
x > -2
=> Yes
C) 1/4x - 16 > -18
1/4x > -2
x > -8
=> Yes
D) -3/2x - 11/4 ≥ 31/4
-3/2x ≥ 42/4
-3/2x ≥ 21/2
x ≤ -7
=> No
E) -8/3x + 5 ≤ 9
-8/3x ≤ 4
x ≥ -4 x 3/8
x ≥ -3/2
=> Yes
Answer:
Length: 14 feet Width: 1 foot
Step-by-step explanation:
This is the only way to have a rectangle that has a perimeter of 30 feet, and an area of 14 feet.
For perimeter:
14 + 14 = 28
1 + 1 = 2
2 + 28 = 30
These dimensions have a perimeter of 30.
For area:
14 x 1 = 14
These dimesnions also have an area of 14.
So, 14 and 1 are the correct dimensions!
I hope this helps you
x^2-6x+9= -1
(x-3)^2= -1
(x-3)^2=i^2
x-3=i
x=3+i
x=3-i
or we can find disctirminant
x^2-6x+10=0
a=1
b= -6
c=10
disctirminant=b^2-4ac
disctirminant=(-6)^2-4.1.10
disctirminant=36-40
disctirminant= -4
i^2= -1
x1,2= -b (+,-) square root of disctirminant /2a
x1= -(-6)+square root of -4/2.1
x1=6+2i/2=3+i
x2= -(-6)-square root of -4/2.1
x2=6-2i/2=3-i

Answer:
Step-by-step explanation:
Given
Temperature = 12 degrees below 0
Required
Represent as an integer
12 degrees below 0 means that the temperature is less than 0.
This can then be expressed as:
Hence, the integer that represents this scenario is -12
