the equation y = 15x describes the amount of money Sandra earns, where x is the number of hours she works and y is the amount of money she earns. the table shows the amount of money Susan earns for different numbers of hours worked. (a) how much money does Sandra earn per hour? (b) who earns more per hour?

Answers

Answer:

(a) Sandra earns $15 per hour

(b) Sandra earns more per hour

Step-by-step explanation:

(a) y=15x tells Sandra's earnings for x hours. To find Sandra's earnings for 1 hour, let x=1.

... y = 15·1 = 15 . . . . Sandra earns $15 in 1 hour.

(b) To find Susan's earnings you can choose any number of hours and divide that into the corrsponding number of dollars. The math is really easy if you choose the last table entry:

... $80/(10 hours) = $8/hour

Sandra's earnings of $15 per hour are more than Susan's earnings of $8 per hour.

_____

Another way to compare the wages is to pick one of the hour numbers from the table and compute Sandra's equivalent earnings. Again, if we choose 10 hours, the math is easy

... y = 15·10 = 150

Sandra earns $150 for 10 hours' work, while Susan only earns $80 for the same time.

So based on the table, Susan's equation describing her earnings is:

y=8x   (x being the hours, y amount earned)

(a) Sandra earns $8 per hour (the factor in front of x in the equation)

(b) Sandra's equation is y=15x which means for every unit of time she adds $15, so her hourly pay is $15. Therefore Sandra earns ($7) more per hour than Susan.

According to the synthetic division below, which of the following statements are true?

Check all that apply.

Answers

A, D and E are correct

given ( x - 4 ) is a factor then x =  4 is a root

the remainder on division by (x - 4 ) = 0 as indicated by the 0 on the right side of the quotient

(x - 4 ) is a factor of 3x² - 13x + 4 → A

the number 4is a root of f(x) = 3x² - 13x + 4 → D ( explained above )

thus 3x² - 13x + 4 ÷ (x - 4 ) = 3x - 1 → E

the quotient line 3 - 1 0

3 and - 1 are the coefficients of the linear quotient and 0 is the remainder

Here, the monic polynomial   is divided by the polynomial   that provides the polynomial   after division that is also a factor of the polynomial  .

Given:

The synthetic division is given below.

[tex]\begin{aligned}4\left){\vphantom{1{\underline {\begin{array}{*{20}{c}}3&{ - 13}&4\\{  }&{12}&{ - 4}\end{array}} }}}\right.\!\!\!\!\overline{\,\,\,\vphantom 1{{\underline {\begin{array}{*{20}{c}}&3&{ - 13}&4\\{    }&{12}&{ - 4}\end{array}} }}} \hfill \\\begin{array}{*{20}{c}}{{\text{    }}3}&{ - 1}&{{\text{    }}0}\end{array} \hfill\\\end{aligned}[/tex]  

Step by step explanation:

We have to determine the answer among all the options.

Option A: [tex]\left( {x - 4} \right)[/tex] is a factor of [tex]3{x^2} - 13x + 4[/tex].

It can be observed from the given synthetic division the polynomial is [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] that is divisible by the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the polynomial [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] is a factor of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the option A is correct option.

Option B: [tex]\left( {x + 4} \right)[/tex] is a factor of [tex]3{x^2} - 13x + 4[/tex].

From the option A, it has been proved that [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] is a factor of the polynomial  

[tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex]

Therefore, [tex](x+4)[/tex] is a not factor of [tex]3{x^2} - 13x + 4[/tex].

Thus, the option B is not correct option.

Option C: The number [tex]-4[/tex] is a root of  [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

From the option A, it has been proved that [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] is a factor of the polynomial  

[tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex]

Now substitute 0 for [tex]g\left( x \right)[/tex] in the equation [tex]g\left( x \right) = \left( {x - 4} \right)[/tex] to find the root of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex] as,

[tex]\begin{aligned}0&= \left( {x - 4} \right) \hfill\\x&= 4 \hfill\\\end{aligned}[/tex]  

It can be seen that the value of [tex]x[/tex] is 4 it means [tex]-4[/tex] is not a root of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the option C is not correct option.

Option D: The number [tex]4[/tex] is a root of [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

It can be seen that the value of [tex]x[/tex] is 4 in option C it means [tex]4[/tex] is a root of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Therefore, the option D is correct option.

Option E: [tex]\left( {3{x^2} - 13x + 4} \right) \div \left( {x - 4} \right) = \left( {3x - 1} \right)[/tex]  

The option E is also correct as [tex](x-4)[/tex] is the factor of the polynomial  [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Option F: [tex]\left( {3{x^2} - 13x + 4} \right) \div \left( {x + 4} \right) = \left( {3x - 1} \right)[/tex]  

The option F is not correct as [tex]\left( {x + 4} \right)[/tex] is not the factor of the polynomial [tex]F\left( x \right) = 3{x^2} - 13x + 4[/tex].

Result:  

Therefore, the correct options are [tex]\boxed{{\mathbf{Option A, D and E}}}[/tex].

how do you find a parallel aandmd perpendicular line using a graph

Answers

The problem asks for the equations of the lines, so you use the information given in the graph to help you write the equations.

The given line has a "rise" of -4 for a "run" of 1, hence a slope of -4/1 = -4. This is the information you need from that line to write the equations of lines through the given point, (4, 3).

(a) The parallel line will have the same slope. You are asked for "an equation", so the simplest is to provide the necessary equation in point-slope form.

The equation of a line with slope m through point (h, k) is ...

... y - k = m(x - h)

For m = -4, (h, k) = (4, 3) your parallel line is ...

... y - 3 = -4(x -4)

(b) The perpendicular line will have a slope that is the negative reciprocal of that of the given line: -1/-4 = 1/4. Using the same point-slope form, your perpendicular line has equation ...

... y - 3 = (1/4)(x - 4)

A gold mine has two​ elevators, one for equipment and another for the miners. The equipment elevator descends 4 feet per second. The elevator for the miners descends 15 feet per second. One​ day, the equipment elevator begins to descend. After 30 ​seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 14 seconds? At that​ time, which elevator is​ deeper?

Answers

Final answer:

The equipment elevator descends to 176 feet below the surface while the miners' elevator descends to 210 feet below the surface after 14 seconds. Therefore, the miners' elevator is deeper.

Explanation:

To solve this, we first need to determine the position relative to the surface of both elevators in the gold mine. As the equipment elevator begins to descend first and moves at a speed of 4 feet per second, it had already traveled 30 (seconds) * 4 (feet per second) = 120 feet downward before the miners' elevator begins to descend.

Then, an additional 14 seconds pass. In these 14 seconds, the equipment elevator will descend a further 14 * 4 = 56 feet. Therefore, the equipment elevator is 120 + 56 = 176 feet below the surface.

The miners' elevator descends at 15 feet per second, and it has been moving for 14 seconds. Therefore, it is 15 * 14 = 210 feet below the surface. At this point in time, the miners' elevator is deeper than the equipment elevator by 210 - 176 = 34 feet.

Final answer:

The equipment elevator will be at a depth of 176 feet, while the miners' elevator will be deeper at a depth of 210 feet from the surface after the given time. The miners' elevator is deeper.

Explanation:

The position of each elevator relative to the surface after another 14 seconds can be found by first determining the distance each has traveled. The equipment elevator descends at 4 feet per second, and it had already been descending for 30 seconds before the miners' elevator started. Therefore, by the time the miners' elevator begins to descend, the equipment elevator will have descended 4 feet/second * 30 seconds = 120 feet.

From that point, after another 14 seconds, the equipment elevator descends an additional 4 feet/second * 14 seconds = 56 feet. Thus, its total descent is 120 feet + 56 feet = 176 feet from the surface.

On the other hand, once the miners' elevator starts, it descends at a rate of 15 feet per second. After 14 seconds, the miners' elevator will have descended 15 feet/second * 14 seconds = 210 feet.

Comparing both distances, the elevator for the miners is at 210 feet while the equipment elevator is at 176 feet from the surface. So, the miners' elevator is deeper.

The U.S. Maritime Administration estimated that the cost per ton of building an oil tanker could be represented by the model y=104,000/x+235 where y is the cost in dollars per ton and x is the tons (in thousands). What size of oil tanker (in thousands of tons) can be built for $350 per ton? a. 62 thousand tons b. 6 thousand tons c. 532 thousand tons d. 178 thousand tons

Answers

(c)

substitute x = 350 into the equation for y

y = [tex]\frac{104000}{350}[/tex] + 235 ≈ 532 000


Final answer:

To find the size of the oil tanker that can be built for $350 per ton, solve the equation 350 = 104,000/x + 235 for x, yielding approximately 904 thousand tons. None of the multiple-choice options match this result.

Explanation:

The student is asked to calculate the size of an oil tanker that can be built for $350 per ton using the given model for cost per ton, which is y = 104,000/x + 235, where y is the cost in dollars per ton, and x is the tons in thousands. To find x, set the equation equal to 350 and solve for x.

350 = 104,000/x + 235

Subtract 235 from both sides to get:

350 - 235 = 104,000/x

115 = 104,000/x

To solve for x, multiply both sides by x and then divide both sides by 115:

x = 104,000 / 115

x ≈ 904.35

Since x is in thousands of tons, the size of the oil tanker that can be built for $350 per ton is approximately 904 thousand tons. However, this answer does not match any of the options provided in the multiple choice (a. 62 thousand tons, b. 6 thousand tons, c. 532 thousand tons, d. 178 thousand tons), suggesting there might be an error in the question or the offered choices.

[tex]8x-4x=4x-24-4x[/tex]

Simplify.

[tex]4x=-24[/tex]

Divide by 4 from both sides of equation.

[tex]\frac{4x}{4}=\frac{-24}{4}[/tex]

Simplify it should be correct answer.

Consider the expression . It has been simplified below with some values unknown.
-33/-10- (-45.3+ 35.2)= -33/-10+?

What is the smallest and largest unknown value from the equation? Must say the smallest value and largest value.

Answers

Given expression is

-33/-10- (-45.3+ 35.2)

Problem says that it is simplified.

After simplification it gives:

-33/-10+?

Now we need to find the unknown value that goes in place of ?.

Notice that it is expression having only constants so we will get a unique answer not the smallest or largest value.


Now let's find the value of unknown that goes in place of ?

-33/-10- (-45.3+ 35.2)= -33/-10+?

we see that -33/-10 is on both sides so we can remove that

- (-45.3+ 35.2)= ?

Now let's simplify the left side by distributing the negative sign

+45.3 - 35.2= ?

10.1 = ?

Hence the unknown value is 10.1 that goes in place of ?.

how do i wright linear functions

Answers

Givenf(5) = -1f(0) = -5Findwrite the linear function f(x)Solution

A linear function is the equation of a line. Here, you are given two points on the line, one of which is the y-intercept, and asked to write the equation. It can work reasonably well to use the 2-point form of the equation of a line.

For points (x1, y1) and (x2, y2), the equation of the line through them can be written as

... y = (y2 -y1)/(x2 -x1)·(x -x1) + y1

When it is possible to use x1 = 0, this is simplified somewhat, so we choose

... (x1, y1) = (0, -5) . . . . . . from f(0) = -5

... (x2, y2) = (5, -1) . . . . . .from f(5) = -1

Putting these values in the above formula, we get ...

... y = (-1 -(-5))/(5 - 0)·(x -0) -5

... y = 4/5x -5 . . . . . simplified

This can be put in the desired functional form using f(x) instead of y:

... f(x) = 4/5x -5

Here we're given two points on a line:  (0,-5) and (5, -1).  Going from the first point to the second, x increases by 5 and y increases by 4.  Thus, the slope of the line is

m = 4/5 = 1.         Use the point-slope formula to find the equation of this line:

                                   y-(-5) = (4/5)(x).  Thus, y = (4/5)x - 5 or f(x) = (4/5)x - 5

Carmen is designing an intersection of the rail line and four streets. She wants to know which streets are parallel

Which streets are parallel? Check all that apply.
c || d
c || e
c || f
d || e
d || f
e || f

CHECK ALL THAT APPLY ITS NOT ONE ANSWER

Answers

Answer:

  d║e, c║f

Step-by-step explanation:

The acute angle of intersection of e with t is ...

  180° - 112° = 68°

This angle is the same as the acute angle at d, so d and e are parallel.

The acute angle of intersection of c with t is ...

  180° -114° = 66°

This angle is the same as the acute angle at f, so c and f are parallel.

  d║e, c║f

_____

Note that the acute angles at the intersections with t are all "corresponding". That is why their congruence means the associated lines are parallel.

The perimeter of an isosceles triangle is 7.5m, and the length of a leg is 2m. Find the length of the base.

Answers

Answer:

3.5 m

Step-by-step explanation:

The perimeter is the sum of the lengths of the three sides of the triangle, so is the sum of two legs and the base.

... 7.5 m = (2 m) + (2 m) + base

... 3.5 m = base . . . . . . subtract 4 m

base = 3.5m

Since the triangle is isosceles both legs are equal to 2m

base = 7.5 - 2 - 2 = 3.5m


Solve for x: 3x − 24 = 81

Answers

To solve for x, we need to get all our constants on one side of the equal sign and all our variables on the other side of the equal sign.


3x - 24 = 81

3x -24 + 24 = 81 +24

3x = 81 + 24

3x = 105

3x/3 = 105 / 3

x = 105 / 3



Answer:

[tex]x=\frac{105}{3}[/tex]
