Answer:
x=90/16,y=-150/16
Step-by-step explanation:
Simultaneous equation and we are to use elimination method
9x+y=30...(1)
6x-y=15..(2)
Add (1) and (2)
16x=15
Divide both sides by 16
x=15/16
Then substitute the value of x into (2)
6(15/16)-y=15
90/16-y=15
Substrate 15 from both sides
90/16-y-15=0
Add y to both sides
90/16-15=y
Lcm for only the left side which is 16
90-240/16=y
-150/16=y
Therefore x is 90/16 and y is -150/16
answer for this question is 2 is to 4 is to6 is to 7
Euro tunnel : - 115 (115 m below sea level of 0)
-115 = S - 50
-115 + 50 = S
- 65 = S....the sea bed is -65 m (or 65 m below sea level
Based on the given current and the given resistance, the voltage of the current is 14 + j8
<h3>How to determine the voltage of the current?</h3>
From the question, we have the following parameters
current of 4+j2 amps and a resistance of 2-j3 ohms.
This can be rewritten as:
Current (I) = 4+j2 amps
Resistance (R) = 2-j3 ohms.
The formula to calculate voltage is given as
Voltage=(current) × (resistance)
Rewrite as:
V = I * R
Substitute the known values in the above equation
V = (4 + j2) * (2 - j3)
Expand the brackets
V = 8 - j4 + j12 + 6
Collect the like ters
V = 8 + 6 - j4 + j12
Evaluate the like term
V = 14 + j8
Based on the given current and the given resistance, the voltage of the current is 14 + j8
