Question

Use the substitution y = 2x + 3 to solve for
x, if 4(2x + 3)2 - (2x + 3) - 14 = 0.​

Answer 1

Answer:

(4*y*2) -y-14=0

8y-y=14

7y=14

y=2

since,

y = 2x + 3

2=2x+3

2-3=2x

-1=2x

x=-0.5

Answer 2

Step-by-step explanation:

Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.
