The variation from x to y is an illustration of a direct variation
The value of x when y = 2 is -19/7
<h3>How to determine the value of x?</h3>
The variation is a direct variation.
So, we have:
x = ky
Where k represents the constant of variation
Make k the subject
k = x/y
This gives
x1/y1 = x2/y2
So, we have:
-19/14 = x/2
Multiply both sides by 2
x = -19/14 * 2
Evaluate
x = -19/7
Hence, the value of x when y = 2 is -19/7

Let d = Darlene's dog's weight
let l = Leah's dog's weight
d = 5l
d + l = 84
so, 5l + l = 84, which means 6l= 84
so, l = 84/6 = 14d = 5(14) = 70
<span>Darlene's dog = 70 lbs, Leah's dog = 14 lbs</span>
Answer:
E = 3072i - 5904ohms
Step-by-step explanation:
From ohms law recalled that E = IR given already
E = voltage (volts)
I = Current (amps)
R = resistance (ohms)
Therefore, by substitution
I = 16i and R = (2+4)ohms(32+66i)
= 6(32+66i) ohms
= (192+396i)ohms
E = (16i)×(192+396i)
E = 3072i + 5904i²
Recall that i² = -1 from complex number
E = 3072i +5904(-1)
E = 3072i - 5904ohms
