Equality Properties

Step-by-step explanation:

Step 1: Define Equation

m - 4m = -6

Step 2: Solve for m

Combine like terms: -3m = -6
Divide -3 on both sides: m = 2

Step 3: Check

Plug in m into the original equation to verify it's a solution.

Substitute in m: 2 - 4(2) = -6
Multiply: 2 - 8 = -6
Subtract: -6 = -6

Here we see that -6 does indeed equal -6.

∴ m = 2 is the solution to the equation.

Answer:

Pilar va a pagar en total por el coche 14209.84€.

Step-by-step explanation:

Pilar ha comprado un coche, da una entrada y lo quiere pagar en 12 meses.

Cada mes va a pagar 600,82€. Como lo quiere pagar en doce meses, luego de finalizado ese tiempo el precio pagado se calcula como:

12 meses* 600,82€ por mes= 7209,84€

Por otro lado, Pilar ha dado al principio una entrada de 7000€. Entonces, el total a pagar por el coche es calculado como:

7000€ + 7209,84€= 14209.84€

Pilar va a pagar en total por el coche 14209.84€.

Plz help last one ty!!!!!!!

azamat

My apologies on answering late...

Same situation as the previous problem, but this time, all you need to do is state the degree of the angle instead of just providing the angle itself.

ΔABC ≅ ΔDEF

Now, we can see that ∠C ≅ ∠F. Using this information, we can find ∠C on the first triangle ( which is $75$ ° ).

Since ∠C ≅ ∠F,

m∠F is $75$ °.

Hope I caught your question in time!

Have a good one! If you need anymore help, let me know.

Fins the zeroes of the quadratic equation : 4√ 5 x^ 2 - 24x - 9√ 5

liubo4ka [24]

Answer:

Step-by-step explanation:

Hello,

First of all, we know that the solution of the following equation

$ax^2+bx+c=0$

are

$\dfrac{-b\pm\sqrt{b^2-4ac}}{2a} \ \text{ when } \Delta=b^2-4ac \geq 0$

I would suggest that you try to apply this formula first and check the solution only after you try.

Let's apply it in this case, we have:

$a=4\sqrt{5} \\ \\ b=-24 \\ \\ c= -9\sqrt{5}$

$\Delta=b^2-4ac=24^2+4*9*5=1296 \\ \\ \sqrt{\Delta}=36 \ \text{ and the solutions are } \\ \\ \\ x_1=\dfrac{24-36}{8\sqrt{5}}=\dfrac{-12}{8\sqrt{5}}=\boxed{\dfrac{-3}{2\sqrt{5}}} \\ \\x_2=\dfrac{24+36}{8\sqrt{5}}=\dfrac{60}{8\sqrt{5}}=\boxed{\dfrac{15}{2\sqrt{5}}}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
