For the x intercept, also known as the zero, we set y=0 and solve for x.

-4x = 20

x = 20/(-4)

x = -5

The x axis is the line y=0 so the y coordinate of an x intercept is always 0.

Answer: (-5, 0)

To find the x-intercept of any equation, set y=0 and solve for x. For the given equation −4x+5y=20, setting y=0 results in the x coordinate -5, making the x-intercept of the line (-5,0).

The x-intercept of any equation is the point where the line crosses the x-axis. At this point, the y-value is always zero because it lies on the x-axis. In the case of the equation −4x+5y=20, we can find the x-intercept by setting y=0 and solving for x.

So, substituting y=0 into the equation, we find:
-4x + 5(0) = 20
Simplifying, this becomes -4x = 20. Dividing both sides by -4, we get x = -5.

So, the x-intercept of the line represented by the equation -4x +5y = 20 is (-5,0).

The answer is choice D.

First, find the slope (m) using the formula: [tex]m=\frac{y_{2}- y_{1} }{x_{2} - x_{1} }[/tex]

[tex]m=\frac{11 - 6}{-1 - 0}[/tex] = [tex]m=\frac{5}{-1}[/tex] = -5

Next, plug in the slope (m) and ONE point (x₁, y₁) into the Point-Slope equation:

y - y₁ = m(x - x₁)

y - 6 = -5(x - 0)

y - 6 = -5x

   y = -5x + 6

Answer:

$639.98 is budgeted for the rent.

Step-by-step explanation:

Joshua's monthly salary is $2,909 and the budget for the rent is 22% of her salary.

For finding the amount of rent, we just need to find 22% of $2909. For that, first we need to convert 22% into decimal by dividing it by 100 and then multiply this result with $2909.

So, [tex]22\%= \frac{22}{100}=0.22[/tex]

Now,  [tex](\$2909*0.22)= \$639.98[/tex]

Thus, $639.98 is budgeted for the rent.

Answer:

I think that the answer is A. x=11/c

Step-by-step explanation:

According to the table given:

Total number of students are = 20

Total number of boys are = 13 , out of which, 3 will be clowns, 2 will perform acrobats and 8 will be elephant trainers.

So, we have to find the the probability that the person(a boy) is a clown. The probability will be = [tex]\frac{3}{13}=0.230[/tex]

Hence, answer is 0.230

The probability the person is a clown, given they are a boy is:

                            0.23077

Let A denote the event that the person is a boy.

Let B denote the event that the person is a clown.

Then  A∩B denote the event that the person is a boy and is a clown.

Let P denote the probability of an event.

Hence, from the table that is given to us we get:

  P(A)=0.65

  P(A∩B)=0.15

We are asked to find the  probability the person is a clown, given they are a boy i.e. we are asked to find: P(B|A)

We know that:

    [tex]P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}[/tex]

Hence, from the given values we have:

     [tex]P(B|A)=\dfrac{0.15}{0.65}\\\\\\P(B|A)=\dfrac{15}{65}\\\\\\P(B|A)=\dfrac{3}{13}=0.23077[/tex]

         Hence, the probability is:

                  0.23077

Answer:

a)   Number of laundry he can do with this box  = 78 laundries.

b)   Price he paying for each load =  0.256 $

Explanation:

 Total scoop contained in detergent box = 195 scoops.

 Scoops used by each load of laundry = [tex]2\frac{1}{2} =\frac{2*2+1}{2} =\frac{5}{2}[/tex] scoops = 2.5 scoops

 Number of laundry he can do with this box = 195/2.5 = 78 laundries.

 Price of detergent box = 19.99 $

 Price he paying for each load = Total price/ Number of loads

                                                   = 19.99/78

                                                   = 0.256 $

Answer: She will need 142 ft of curtain.

Step-by-step explanation:

Hi, first we have to convert the length of the curtain from inches to foot.

Since 1 inch = 1/12ft  

For 24 inches:

24 inches x 1/12 = 2 ft

Since the company wants to make 71 curtains, we have to multiply the length of each curtain (2ft) by 71.

2ft x 71 = 142ft

She will need 142 ft of curtain.

so it is 87.5 so what you do do is 25 x 3.50 and it will give you 87.5

Joe has a bonus of $25 and he needs to earn a total of $165. He needs to make $140 on his hourly wage of $3.50. By dividing $140 by $3.50, we find that Joe needs to work 40 hours to reach his goal.

The subject of this question is Mathematics, particularly dealing with real-life word problems. To solve this, we first have to account for the bonus that Joe has already received. If Joe has a bonus of $25 this week, then he needs to earn $165 - $25 = $140 from his hourly wage in order to reach his goal. Joe earns $3.50 per hour. To figure out how many hours he needs to work to earn $140, you divide the total amount of money he needs to earn by the amount he earns in one hour. Hence, $140 ÷ $3.50 = 40 hours. So, Joe needs to work 40 hours to make at least $165 if he gets a bonus of $25 this week.

Answer:

In order to increase humidity by 49.17 grams per kilogram, the increase in temperature will be 18 degree Celsius approx.

Step-by-step explanation:

Initial humidity = 5.75 g/kg

Final humidity= 49.17 g/kg

Percentage increase in humidity= (49.17-5.75)/5.75 *100= 755.13

Increase in temperature= 755.13/43 = 17.56

Increase in temperature = 18 degree Celsius approx.

Answer:

The temperature must increase by more than 6 degree Celsius for the humidity to reach at least 49.17 grams per kilogram

Step-by-step explanation:

Given : Humidity on Monday morning = 5.75 grams per kilogram

To Find: He wants to know how much the temperature must increase for the humidity to reach at least 49.17 grams per kilogram.

Solution :

Let T be the increase in temperature, in degrees celsius, from monday morning.

According to question

The humidity measured in grams of water per kilogram of air, increases by 43% for every 1 degree Celsius increase in temperature.

So. Rate of increment is 43%

So, it becomes : [tex]100+43=143\% =1.43[/tex]

43% increases for every 1 degree celsius.

So, for T the increase is 1.43*T

So, [tex]1.43T\geq \frac{49.17}{5.75}[/tex]

[tex]1.43T\geq 8.55[/tex]

[tex]T\geq \frac{8.55}{1.43}[/tex]

[tex]T\geq 5.97[/tex]

Thus the temperature must increase by more than 6 degree Celsius for the humidity to reach at least 49.17 grams per kilogram

Answer:

Side of Squared shaped plot = x foot

Then the farmer fences off a 25 foot wide section to create an area to store equipment.

As width=25 foot

and Length =x foot

Area = 25 x square foot

So 25 x represents area which is used for storing equipment.

So out of all the options Option D is correct which is The area of the land fenced off to store equipment .

Answer

The statement best describes the term 25x is  option ( D)

i.e  The area of the land fenced off to store equipment.

Reason

As given in the question

A farmer has a square-shaped plot of unused land

After the farmer fences off

he fences off a 25-foot wide section to create an area to store equipment.

x represent the original length of the plot.

this shows that the plot used to store equipment is not square.

Formula

Area of the rectangle = length × breadth

length = x

breadth = 25

put in the above equation

Area = 25x feet²

therefore 25x feet² shows the area of the land fenced off to store the equipment.

Hence proved

answer : 5

For example

The quadratic equation has 1 tuning point. The degree of quadratic polynomial is 2

Cubic polynomial can have 2 turning points. The degree of cubic polynomial is 3

From this we conclude that if a polynomial has 'n' turning points, then the least possible degree is n+1

the graph of a polynomial has 4  turning points, so the least possible degree is

4+1 = 5

5 is the least possible degree of this polynomial

The least possible degree of a polynomial that has four turning points is 5.

In mathematics, specifically in polynomial function, the degree of a polynomial can be linked to its turning points. The turning point of a function is the high point (peak) or low point (trough) of a graph. The degree of the polynomial is one more than the maximum number of turning points. So, if a graph of a polynomial has 4 turning points, the least possible degree of that polynomial would be 5. Therefore, the correct answer is (c) 5.

Answer:

Step-by-step explanation:

Think of of this as a function in which the number of pounds is a function of the number of hours. Each piece of given information is a point. Each point has the format (x, y) = (hours, pounds), where hours is x and is the independent variable, and pounds is y and is the dependent variable.

You have two points (4.5, 1445) and (7, 2320). First find the slope of the line that passes through those two points. Use the slope formula,

m = (y2 - y1)/(x2 - x1).

Then using the slope and the point-slope equation of a line, find the equation of the line. The point-slope equation of a line is

y - y1 = m(x - x1),

where m = slope, and the point is (x1, y1).

Answer:

The correct option is the last one.

Step-by-step explanation:

To transform the graph of [tex]y = x ^ 2[/tex] into [tex]y = -2(x - 2) ^ 2 + 2[/tex] the following steps are fulfilled:

1) Move the graph 2 units to the right:

Let [tex]y = f (x-2)[/tex] then [tex]y =(x-2) ^ 2[/tex] Notice that the cut point has been moved to x = 2.

2) Reflect on the x axis:

To reflect a graph on the x-axis we do [tex]y = -f(x)[/tex] Then [tex]f (x) = -(x-2) ^ 2[/tex]

3) Stretch according to factor 2.

For this we do [tex]y = 2f(x)[/tex]

Then we have [tex]f(x) = -2 (x-2) ^ 2[/tex]

4) Move up the graph in two units:

We do [tex]y = f(x) +2[/tex]

Then [tex]y = -2(x-2) ^ 2 +2.[/tex]

These steps coincide with those listed in the last option. Therefore the correct option is the last one.

"Translate 2 units on the right, reflect on the x-axis, stretch according to the factor 2 and translate 2 units"

To transform the graph from y • x^2 to y = -2(x - 2)^2 + 2, you need to translate 2 units to the right, reflect across the x-axis, stretch by the factor 2, and translate up 2 units.
