Answer:
18i, -7-i, -6+18i
Step-by-step explanation:
1. √-324
first take out the negative as √-1=i
√-324= i√324
324 =2*162
324=2*2*81
324=2*2*9*9
i√324=i√2*2*9*9= i* 2*9= 18i
3.
-4+7i-3-8i combine like terms
-4-3 -8i+7i = -7-i
5.
(1+5i)(4-2i) distribute
1*4 -1*2i +5i*4 -5i*(-2i) multiply
4 -2i +20i +10i² but i²= -1 so
4 -2i +20i -10 combine like terms
-6 +18i
The K-constant variation is the factor of the increase-decrease relationship between the x-variable and y-variable which can be stated as y=k*x or x=y/k<span>. For example, if y variable equal 5 and the x variable equal 2 then the k-constant variation equal 2 (calculation y=k*x --> 5=2*2.5). This constant shows the relationship between the variables.</span>
-5x + 3(2x - 6) = -13
-5x + 6x - 18 = -13
x = 5 => y = 4
Answer:
Let the numbers are
x, (x+2), (x-2) and (x+4)
Step-by-step explanation:
x + x +2 +x - 2+x+4 = 80
4x +4 = 80
4x =80-44x = 76
4x = 76
x = 76/4
x = 19x
x=19
(x+2) =19+2=21
(x-2) = 19-2=17
(x+4)=(19+4)=23
