point A lies at the intersection of y = x and y = -2/3x + 5. What are the coordinates of A? Express your answer as an ordered pa
torisob [31]
Y = x
y = -2/3x + 5

x = -2/3x + 5
x + 2/3x = 5
3/3x + 2/3x = 5
5/3x = 5
x = 5 * 3/5
x = 15/5 reduces to 3

y = x
y = 3

so ur answer is (3,3)

The formula V=IR shows the relationship between voltage, current, and resistance. Solve this formula for R
netineya [11]

Answer:

The formula  is R =\frac {V}{I}

Step-by-step explanation:

The formula V = I R shows the relationship between voltage, current, and resistance.

It is given by the Ohm's law.

According to this law, at constant temperature, the current flows in any conductor is directly proportional to the potential difference applied.

V = I R

where, V is the potential difference, I is the current and R is the resistance.

The resistance is given by

R = \frac{V}{I}
