Factor completely...I need help with my algebra 2 assignment!

Answer:

1.67 hours

Step-by-step explanation:

Let the original speed of Jonathan = [tex]x[/tex] units/hr

Let the original time taken by Jonathan = [tex]y[/tex] hours

Let the distance = [tex]D[/tex] units

Formula for distance is given as:

[tex]Distance = Speed \times Time[/tex]

Given that half the distance is covered by original speed.

[tex]\Rightarrow \dfrac{D}{2} = \dfrac{x}{2}\times \dfrac{y}{2}\\\Rightarrow D = \dfrac{xy}{2} ..... (1)[/tex]

Half the distance is covered by increasing the rate by 25%.

i.e. increased speed:

[tex]\dfrac{5}{4}x\ units/hr[/tex]

Hence, Time taken:

[tex]\dfrac{y}{2}-\dfrac{1}{2}[/tex]

Distance traveled is half of the total distance:

[tex]\Rightarrow \dfrac{D}{2} = \dfrac{5x}{4}\times (\dfrac{y}{2}-\dfrac{1}{2})\\\Rightarrow D = \dfrac{5x}{2}\times (\dfrac{y}{2}-\dfrac{1}{2}) .... (2)[/tex]

Dividing (1) by (2):

[tex]\dfrac{xy\times 4}{2\times 5x(y-1)} = 1\\\Rightarrow 2y=5y-5\\\Rightarrow 3y=5\\\Rightarrow y =1.67\ hours[/tex]

Answer:

Costo fijo= $104.5

Costo unitario=  $0.5 por minuto

Step-by-step explanation:

Mes pasado:

$239 por 269 minutos

Mes corriente:

$175 por 141 minutos

Primero debemos calcular el cost por minuto de llamada:

Costo unitario= (costo total más alto - costo total más bajo) / (cantidad de minutos más alto - cantidad de minutos más bajo)

Costo unitario= (239 - 175) / (269 - 141)

Costo unitario=  $0.5 por minuto

Ahora, el costo fijo:

Costo fijo= costo total más alto - (costo unitario*cantidad de minutos más alto)

Costo fijo= 239 - (0.5*269)

Costo fijo= $104.5

Costo fijo= costo total más bajo - (costo unitario*cantidad de minutos más bajo)

Costo fijo= 175 - (0.5*141)

Costo fijo= $104.5

Answer:

I think it’s done like this, I’m not sure

First, collect the like terms

-2x<16-4

-2x<12

x<12/-2

x<-6

So, you substitute -6 instead of x to find which is greater

12+4<16

16<16

Which makes it false

Step-by-step explanation:

I hope I explained well, please give me brainliest

The solution of the inequality - 2x + 4 < 16 will be;

⇒ - 6 < x

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ - 2x + 4 < 16

Now,

Solve the expression as;

⇒ - 2x + 4 < 16

Subtract 4 both side, we get;

⇒ - 2x + 4 - 4 < 16 - 4

⇒ - 2x < 12

Divide by 2 , we get;

⇒ - x < 6

Multiply by - 1, we get;

⇒ x > - 6

⇒ - 6 < x

Thus, The solution of the inequality - 2x + 4 < 16 will be;

⇒ - 6 < x

Answer:

The Measure of <FBA is 62 degree.

When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. The total of angles of a linear pair is always equal to 180°.

Given:

m∠FBE=(4x+2)° and m∠EBD=(5x−13)°

as, FB bisects <EBA

So, <EBF = <FBA

and,  EB bisects <FBD

So, <FBE= <EBD

4x+ 2 = 5x -13

x= 15

So, <EBF = <FBA = 4x+ 2 = 4(15)+ 2 = 62

Answer:

C

Step-by-step explanation:

-18x + 21 > -15  ///  x = 2

20x – 13 >27  ///  x = 2

The solution of inequality -18x + 21 > -15 OR 20x – 13 > 27 is x ∈ (- ∞, ∞), so option E is correct.

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.

Given:

-18x + 21 > -15 or  20x – 13 >27

Solve the first inequality as shown below,

-18x + 21 > -15

-18x + 21 - 21 > -15 - 21       (Subtract 21 from both sides)

-18x > -36

-18x / -18 > -36 / -18      (Divide by -18 into both sides, the inequality sign changes as the value will become positive)

x < 2

Similarly, solve the second inequality,

20x – 13 > 27

20x > 40

x > 2

Thus, the solution will be x < 2 ∪ x > 2 or x ∈ (- ∞, ∞)

Answer:

Total gallons= 597,420

Step-by-step explanation:

Giving the following information:

Pump A dispensed 241,752 gallons.

Pump B dispensed 113,916 more gallons than Pump A.

First, we will calculate the number of gallons dispensed by Pump B:

Pump B= Pumb A + 113,916

Pump B= 241,752 + 113,916

Pump B= 355,668 gallons

Now, in total:

Total gallons= 241,752 + 355,668

Total gallons= 597,420

Answer:

-30

Step-by-step explanation:

7x-4=-28-6=-34+4=-30

Pls mark as brainliest!!!!!

Answer:

The answer for this is -30.

Step-by-step explanation:

Basically, you start out with solving the equation from left to right (as always). First, you multiply 7* -4, and you get -28. Then you have -28 - |-6| + |4|. Now, |-6| is equal to 6, since it's the absolute value of -6. |4| is equal to 4 for the same reason as well. That leaves you with -28 - 6 + 4. Now you just solve left to right. -28 - 6 is -34, so then you have -34 + 4, which is equal to -30.
