Answer:

x > 5

Step-by-step explanation:

Given that:

= -2(3x + 2) > -8x + 6

By simplifying

= -6x - 4 > -8x +6  (- sign before bracket will alter the internal signs)

Taking variables (x terms ) on left side and constants on right side

= -6x + 8x > 6 +4

Signs of transferred terms will be changed

= 2x > 10

Dividing both sides by 2 we get

=x > 10/2

= x > 5

I hope it will help you!

Given the following information, find the length of the missing side. Leave your answer as a simplified radical.
andreev551 [17]

Answer:

2√3

Step-by-step explanation:

Given the following information,

Long = 3 = Adjacent

Angle of elevation =30 degrees

Required

Hypotenuse

Using SOH CAH TOA identity

Cos theta = adj/hyp

Cos 30 = 3/hyp

hyp = 3/cos30

hyp = 3/√3/2

hyp = 3* 2/√3

hyp = 6/√3

hyp = 6/√3 * √3/√3

hyp = 6√3/3

hyp = 2√3

Hence the hypotenuse is 2√3

consider the quadratic function: f(x) = x2 – 8x – 9 Vertex: What is the vertex of the function? ( , )
Aleksandr [31]

Answer:

The vertex point of the function is (4 , -25)

Step-by-step explanation:

- Lets explain how to find the vertex of the quadratic function

- The form of the quadratic function is f(x) = ax² + bx + c , where

 a , b , c are constant

# a is the coefficient of x²

# b is the coefficient of x

# c is the y-intercept (numerical term)

- The x-coordinate of the vertex point is -b/a

- The y-coordinate of the vertex point is f(-b/a)

* Lets solve the problem

∵ f(x) = x² - 8x - 9

∴ a = 1 , b = -8 , c = -9

∵ The x-coordinate of the vertex point is -b/a

∴ The x-coordinate of the vertex point = -(-8)/2(1) = 8/2 = 4

- To find the y-coordinate of the vertex point substitute x by 4 in f(x)

∵ f(4) = (4)² - 8(4) - 9

∴ f(4) = 16 - 32 - 9

∴ f(4) = -25

∵ f(4) is the y-coordinate of the vertex point

∴ The y-coordinate of the vertex point is -25

∴ The vertex point of the function is (4 , -25)

The sum of five times h and twice g is equal to 23
Mariana [72]

answer: 5h + 2g = 23

to solve problems like this, pull apart the equation.

the sum of five times h and twice g is equal to 23

so, we know we're going to be adding two terms, what are they?        

five times h and twice g

so, 5h + 2g.

what does it equal?

the sum of five times h and twice g is equal to 23

this means  5h + 2g = 23
