Ok so since each pie requires 3 cups of sugar, you would just multiply the x value by 3. For example for one pie three cups of sugar are needed, for two pies six cups of sugar are needed, for three pies nine cups of sugar are needed etc. Hopefully this helps!

What is the first step in solving the quadratic equation -5x2+8=133?

ololo11 [35]

Answer:

b. The first step in the equation solving is subtracting 8 from both sides of the equation.

Step-by-step explanation:

Here, the given quadratic equation is : $-5x^2 + 8 = 133$

Let us try and solve this given equation.

$-5x^2 + 8 = 133 \\\implies -5x^2 + 8 - 8 = 133 -8\\\implies -5x^2 = 125\\\implies x^2 =\frac{125}{-5} = -25\\\implies x^2 = -25 = (5i)^2$

So, x = ± 5i

Hence, as we can see here, the first step in the equation solving is subtracting 8 from both sides of the equation.
