Answer:

Bottom left graph

Step-by-step explanation:

<u>Given function:</u>

y = -x^3 + ax^2 + bx + c

This is a third degree function with negative leading coefficient.

This is therefore decreasing function and can have one local maximum and one local minimum.

From the given graphs we can see only bottom left one can be a matching one.

Jace walked a total distance of StartFraction 5 Over 6 EndFraction of a mile to school this week. If he walked the same distance

xxMikexx [17]

He walks 5/6 of a mile each day.

Multiply the distance each day by the number of days:

5/6 x 5

When multiplying a fraction by a whole number, multiply the numerator ( top number) by the whole number and leave the denominator ( bottom number as is)

5/6 x 5 = (5 x5)/6 = 25/6 now rewrite as a proper fraction:

25/6 = 4 1/6 total miles.

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.
