Answer:

  x  <  6.4  

Step-by-step explanation:

given,

       -8 - 5 x + 2 > -38

           - 5 x - 6 > -38

adding both side by 6

           - 5 x - 6 + 6  > -38 + 6

             - 5 x  > -32

multiplying both side by (-1)

                5 x  <  32        

on multiplying by negative sign the inequality direction changes

                  x  <  6.4  

the graph is shown in the figure attached below. the shaded region shows the required area.

A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time.

“Or” indicates that, as long as either statement is true, the entire compound sentence is true.

Now as shown in the graph, the solution inequality of the graph is :

x > 3 and x < 5   [please note, circles in the graph indicate exclusion, dots indicate inclusion. in the graph given circles are shown, so it depicts exclusion]

Now let's solve each option to find if it fits in with the above inequality

Option 1 : 2x-4 > 6 or 3x < 9

⇒ x > 5 or x < 3

Option 2 : 2x - 4 < 6 and 3x > 9

⇒ x < 5 and x > 3

Option 3 : 3x + 8 > -7 or -4x < 12

⇒ 3x > -15 or x < -3

⇒ x > -5 or x < -3

Option 4 : 3x + 8 < -7 and -4x > 12

⇒ 3x < -15 and x > -3

⇒ x < -5 and x > -3

So the compound sentence in option 2 : 2x - 4 < 6 and 3x > 9

has its solution set on the graph.

n = 8

the sum to n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a(1-r^{n )} }{1-r}[/tex]

where a is the first term and r the common ratio

here a = 16 and r = [tex]\frac{64}{-32}[/tex] = [tex]\frac{-32}{16}[/tex] = - 2

[tex]S_{n}[/tex] = ( 16( 1 - ( - 2 )^n )/1 - (- 2 )) = - 1360

[tex]\frac{16}{3}[/tex] ( 1 - (- 2 )^n ) = - 1360

multiply both sides by [tex]\frac{3}{16}[/tex]

1 - (- 2 )^n = - 255

- (- 2 )^n = - 256

)-2)^n = 256

note that [tex]2^{8}[/tex] and [tex](-2)^{8}[/tex] = 256

Answer: A. Based on the law of syllogism, if two lines meet at a 90 angle, then they have opposite reciprocal slopes.

Step-by-step explanation:

Law of Syllogism which is also known as reasoning by transitivity is a valid argument method of a deductive reasoning that follows a sequence.

Its similar to the transitive property of equality, which states that if a=b and b=c then a=c

The given statement :  If two lines meet at a 90 angle, they are perpendicular. If two lines are perpendicular, they have opposite reciprocal slopes.

let a →" two lines meet at a 90 angle"

b→ "two lines are perpendicular are perpendicular"

c→" two lines have opposite reciprocal slopes"

Since a→b and b→c

Therefore by law of syllogism, a→c

i.e. If two lines meet at a 90 angle, then they have opposite reciprocal slopes.

Answers:

a. The company needs to sell 100 units to reach the maxmum profit.

b. The company's maximum profit is $5,000.

Solution:

a. How many unit does the company need to sell to reach the maximum profit?

p(x)=-0.5x^2+100x

This is a quadratic equation, and its graph is a parabola vertical (because the veriable "x" is square). Comparing with the general form:

p(x)=ax^2+bx+c; a=-0.5, b=100, c=0

a=-0.5<0 (negative), then the parabola opens downward, and it has a maximimun value (maximum profit) at its vertex.

We can find the abscissa of the vertex (units that the company needs to sell to reach the maximum profit using the following formula:

x=-b/(2a)

Replacing b by 100 and a by -0.5 in the formula above:

x=-100/[2(-0.5)]

x=-100/(-1)

x=100

The company needs to sell 100 units to reach the maximum profit.

b. What's the company's maximum profit?  

To determine the maximum profit we substitute the value of "x" obrained in part "a" in the quadratic equation:

x=100→p(100)=-0.5(100)^2+100(100)

p(100)=-0.5(10,000)+10,000

p(100)=-5,000+10,000

p(100)=5,000

The company's maximum profit is $5,000.

Final answer:

The correct expression to find the temperature difference between the low and high temperatures when the temperature rose as much above zero as it was below zero is 5 + 5 degrees, which equals 10 degrees in total.

Explanation:

The question involves finding the difference in temperature from a low of -5 degrees Fahrenheit to a high that is as many degrees above zero as the low was below zero. To calculate the difference, we consider the increase in temperature from the low to 0 degrees, which is 5 degrees, and then the additional increase to the high temperature, which is also 5 degrees above zero. Therefore, the total change in temperature is 5 degrees (to get to zero) plus another 5 degrees (to reach the high), totaling 10 degrees.

The correct expression to find the number of degrees between the low and high temperatures would be C. 5 + 5, representing the increase from -5 degrees to 0, and from 0 to +5 degrees, respectively.

Two consecutive odd numbers are 71 and 73 such that their sum is 144.

Continually following one another in a regular counting order or in the order of smallest to greatest are numbers known as consecutive numbers.

Let first odd number is x

then second consecutive odd number will be x+2

Given that the sum is 144

So,

x+(x+2)=144

On solving and adding like terms

2x+2=144

On subtracting 2 both sides

2x+2-2=144-2

2x=142

On dividing 2 both sides

x=142/2

x=71

Thus, two consecutive odd numbers are 71 and 73.

If you cancel out the denominators by multiplying both sides by the bottom, you can then factor to find X= a / (a-b)

To solve the equation 5a/x = 5b/(x-1) for x, multiply both sides of the equation by x(x-1) to clear the fractions. Simplify and solve for x by isolating it on one side of the equation.

To solve the equation 5a/x = 5b/(x-1) for x, we need to clear the fractions by multiplying both sides of the equation by the common denominator, x(x-1). This gives us 5a(x-1) = 5bx. Expanding the equation, we get 5ax - 5a = 5bx. Rearranging the terms, we have 5ax - 5bx = 5a. Factoring out x, we get x(5a-5b) = 5a. Finally, dividing both sides by (5a-5b), we can solve for x as x = 5a/(5a-5b).
