Answer:
x > -24
Step-by-step explanation:
18 - 3x < 90
Subtract 18 from both sides.
-3x < 72
Divide both sides by -3. (When diving by a negative, flip the sign.)
x > -24
Answer: the answer would be A. the number of hours Noel worked
sorry i responded so late but i hope this helps you
Step-by-step explanation:
Answer:
the modulus of a complex number z = a + bi is:
Izl= √(a²+b²)
The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:
m = 2 + 6i
n = a + bi
Im + nl = 3√10
√(a² + b²+ 2²+ 6²)= 3√10
√(a^2 + b^2 + 40) = 3√10
squaring both side
a²+b²+40 = 3^2*10 = 9*10 =90
a²+b²= 90 - 40
a²+b²=50
So,
|n|=√(a^2 + b^2) = √50
The modulus of n must be equal to the square root of 50.
now
values a and b such
a^2 + b^2 = 50.
for example, a = 5 and b = 5
5²+5²=25+25= 50
Then a possible value for n is:
n = 5+5i
Answer:
m=2
Step-by-step explanation:
Add the numbers
-7+4m+10=15-2m
3+4m=15-2m
Rearrange terms
3+4m=15-2m
4m+3=15-2m
Rearrange terms
4m+3=15-2m
4m+3=-2m+15
Subtract 3 from both sides of the equation
4m+3=-2m+15
4m+3-3=-2m+15-3
Simplify
4m=-2m+12
Add 2m to both sides of the equation
4m=-2m+12
4m+2m=-2m+12+2m
Simplify
6m=12
Divide both sides of the equation by the same term
6m = 12
6m/6 = 12/6
Simplify
m = 2
