Answer:

z=6 and z=-6

Step-by-step explanation:

7z^2=252

Divide both sides by 7

\frac{7z^2}{7} =\frac{252}{7} \\z^2=36

Find the square root

z=±√36

z=±6

Therefore, z=6 and z=-6.

I hope this helps!

Answer:

  • 13.5 units

Step-by-step explanation:

<u>Use distance formula:</u>

  • d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

<u>Substitute the coordinates:</u>

  • d = \sqrt{(-3-7)^2+(-3-6)^2} =\sqrt{10^2+9^2} =\sqrt{181} =13.5 rounded

Need help with this question. ​
solniwko [45]

We have this equation:

\log(x) + \log(x + 99) = 2

First, combine both logarithms using the multiplication property and simplify the expression.

\log[x(x + 99)] = 2

\log[ {x}^{2} + 99x ] = 2

Now, use the definition of logarithm to transform the equation.

{10}^{2}  =  {x}^{2}  + 99x

{x}^{2}   +  99x  -  100 = 0

Finally, use the quadratic formula to solve the equation.

x =  \frac{ -99 ± \sqrt{ {99}^{2}  - 4 \times 1 \times ( - 100)} }{2 \times 1}

With this, we can say that the solution set is:

  • x = 1
  • x = -100

We cannot choose x = -100 as a solution because we cannot have a negative logarithm. The only solution is x = 1.

VARVARA [1.3K]

The painting's original price was $3,500.

Step-by-step explanation:

Step 1:

The price now is $500 lesser than 3 times the original price. So

The current selling price = (3 × original price) - $500.

If the current selling price is y and the original price is x, then

y = 3x-500.

Step 2:

For this question, we have y = 10,000. Substituting this in the equation, we get

10,000 = 3x - 500, 3x = 10,500, x = \frac{10,500}{3} = 3,500.

So the original price of the classic painting was $3,500.
