-3x>6 What is the solution set?

Mathematics
1 answer:

\boxed{x

<h2>Explanation:</h2>

Here we have the following inequality:

-3x>6

So divide both sides by -3:

\frac{-3x}{-3}

When multiplying or dividing an inequality by a negative number, the direction of the inequality changes. That's the reason why we changed the sign from > to <. Finally, the solution set is:

\boxed{x

If x5y4z2 &lt;0 , which of the following must be true?
devlian [24]

In order for the whole expression to be negative, either  (x⁵) 
or  (y⁴)  or  (z²)  must be negative.

But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.

So  (y⁴)  and  (z²)  are always positive.  The expression can be
negative if 'x' is negative, because  (x⁵)  will then be negative.

None of the proposed requirements is appropriate, so the
final answer is  E. None .

The Vertex of a parabola is at (8-1), and it's why intercept is negative 17, which function represents the parabola
suter [353]

Answer:

The function is equal to y=-(1/4)(x-8)^{2}-1

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2}+k

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(8,-1)

substitute

y=a(x-8)^{2}-1

<u><em>Find the value of a</em></u>

Remember that we have the y-intercept

The y-intercept is the point (0,-17)

substitute

x=0,y=-17

-17=a(0-8)^{2}-1

-17=64a-1

64a=-17+1

64a=-16

a=-16/64

a=-1/4

therefore

The function is equal to

y=-(1/4)(x-8)^{2}-1

see the attached figure to better understand the problem

i need help finding the area of a figure where the rectnagles area is 5 x 14 and the half circles diameter is 6
masha68 [24]

Answer:

  84.14 square units, total

Step-by-step explanation:

Use the formulas for area of the figures you're interested in.

<u>Rectangle Area</u>

  A = LW

<u>Circle Area</u>

  A = πr^2

__

Your rectangle area will be ...

  A = 5 × 14 = 70 . . . . square units

The area of a full circle with diameter 6 (radius = 6/2 = 3) will be ...

  A = π × 3^2 = 9π

The area of a semicircle of that size is half that:

  semicircle area = 9π/2 = 4.5π

Then the total area of the two figures is ...

  70 + 4.5π ≈ 70 +14.14 = 84.14 . . . square units
