Answer:
{3-i, 3+ i}
Step-by-step explanation:
hello : the equation is : x²-6x+10 =0
because : (3+i)²-6(3+i)+10 = 9+6i+i²-18-6i+10 =9+6i-1-18-6i+10 =0...right
same method for 3-i... (all quadratic equation have two conjugate solution)
Answer:
Last option: x = -5
Step-by-step explanation:
-3x + 25 = 40
-3x = 40 - 25
-3x = 15
3x = -15
x = -5
Answer: A) y = 7x
<u>Step-by-step explanation:</u>
In order to be a proportional relationship, the equation MUST pass through the origin (0, 0) and only contain two coordinates
A) 0 = 7(0) ---> 0 = 0 TRUE
B) 0 = 2 + 3(0) ---> 0 = 2 False
C) 0 = Vz(0) ---> Too many variables so False
D) 0 = 5 - 0 ---> 0 = 5 False
Let P = pencil length, M = marker length and Pn = pen length.
We know that the sum of these lengths is 48 cm so:
P + Pn + M = 48 (Equation 1)
Now we need to use the relationships of the lengths to find 2 more equations:
Pn = M - 1 (Equation 2)
M = P - 1 (Equation 3)
Now, sub Equations 2 and 3 into the first equation and solve for the value of P, which is 17.
Next, use the value of P to find your M value and then finally use that M value to get your Pn value.
The final answer is: pencil length = 17cm, marker length = 16cm and pen length = 15cm.
Answer:
224 y/m
Step-by-step explanation:
divide 3136 by 14, to get the yards ran in relation to minutes. you'll get 224 yards per minute (y/m)
