Answer:

(-7, 31)

Step-by-step explanation:

To solve this equation, simply plug in the numbers. For example, with -3 and -11, you simply plug them into the equation:

-11 = -5 (-3) - 4
After you solve this, you'll see the equation does not come out to -11; rather, it comes out to +11.

Repeat this with all equations, and you will see which are correct. Be careful, however, and remember which number goes into which value.

Determine the currents in the picture

Evgesh-ka [11]

Answer:

The value of currents are $I_1=0A$ , $I_2=1A$ and $I_3=1A$ .

Step-by-step explanation:

The Ohm's law states that

$V=IR$

It is given that the V₁=3V and V₂=4V.

In a parallel circuit:

→ Voltage is same in each component

→ Sum of the currents equals to the total current that flows.

$I_2=I_1+I_3$ .... (1)

Equation for first loop is,

$V_1=4I_1+3I_2$

$3=4I_1+3I_2$ ..... (2)

Equation for second loop is,

$V_2=1I_3+3I_2$

$4=1I_3+3I_2$ ..... (3)

On solving (1), (2) and (3) we get

$I_1=0$

$I_2=1$

$I_3=1$

Therefore the value of currents are $I_1=0A$ , $I_2=1A$ and $I_3=1A$ .

-x/3 - 2 less then or equal to 1

Reptile [31]

Answer:

$\huge\boxed{x\geq-9}$

Step-by-step explanation:

$\dfrac{-x}{3}-2\leq1\qquad|\text{add 2 to both sides}\\\\\dfrac{-x}{3}-2+2\leq1+2\\\\\dfrac{-x}{3}\leq3\qquad|\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup\cdot\dfrac{-x}{3\!\!\!\!\diagup}\leq3\cdot3\\\\-x\leq9\qquad|\text{change the signs}\\\\x\geq-9$
