Answer:

[tex]y<-\dfrac{1}{4} x+1\\OR\\ 4y<-x+4[/tex]

Step-by-step explanation:

First of all, let us try to find out the equation.

We can easily observe from the graph the values of x and y intercept.

x intercept is the value where y coordinate is 0.

We can see that y is 0 at x  = 4

So, x intercept (4, 0)

y intercept is the value where x coordinate is 0.

We can see that y is 1 at x  = 0

So, x intercept (0, 1)

Now, we have 2 points for the equation of line.

Slope intercept form:

[tex]y=mx+c[/tex]

Slope of a line:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]x_1 = 0\\x_2 = 4\\y_1 = 1\\y_2 = 0[/tex]

[tex]m=\dfrac{0-1}{4-0}\\\Rightarrow m =-\dfrac{1}{4 }[/tex]

[tex]y=-\dfrac{1}{4} x+c[/tex]

Putting the point (0, 1):

[tex]1=-\dfrac{1}{4} \times 0+c\\\Rightarrow c = 0[/tex]

So, the equation becomes:

[tex]y=-\dfrac{1}{4} x+1[/tex]

Let us try to put a point (0, 0) in the equation.

LHS becomes 0.

RHS becomes 1.

LHS < RHS (Only less than sign used because the line is dashed not solid)

So, the inequality is:

[tex]y<-\dfrac{1}{4} x+1\\OR\\ 4y<-x+4[/tex]

Answer:

0.63 meters

Step-by-step explanation:

Given the following :

1 meter = 100 centimeters

1 centimeter will be (1/100)meter

1 meter is divided into two :

Assume x and y

One part = 0.37 meters, = x

Then y will be :

x + y = 1 meter

x = 0.37

0.37 + y = 1

y = 1 - 0.37

y = 0.63 meters

Hence, the other part will be 0.63 meters

Step-by-step explanation:

Let x and y pounds of Candy A and Candy B be mixed respectively.

Rate of Candy A and Candy B are $0.78 and $1.33 per pound respectively.

Now,

(A) x + y = 8

(B) 0.78x + 1.33y = 7.84

Solving both equations :

0.33y = 1.6

x = 3.16 pounds of Candy A

y = 4.84 pounds of Candy B

Answer:

x = -4/7, y = 2/7

Step-by-step explanation:

Given: f(x) = 3x + 2 and g(x) = - 4x - 2

The point of intersection of the two functions is the point at which both functions intersect. We have to solve the functions simultaneously to get the solution.

f(x) = y = 3x + 2

y = 3x + 2               (1)

g(x) = y = -4x - 2  

y = -4x - 2               (2)

Subtract equation 2 from equation 1:

0 = 7x + 4

7x = -4

x = -4/7

Put x = (-4/7) in y = 3x + 2:

y = 3(-4/7) + 2 = -12/7 + 2 = 2/7

Step-by-step explanation:

Answer:

(csc(ax+b))'=-a csc(ax+b)cot(ax+b)

Step-by-step explanation:

We are asked to find the derivative of csc(ax+b). I assume you are asked to find the derivative with respect to x. If the assumption is wrong, please note so in the comments.

To do this we must use chain rule.

This will require us to know the derivative (w.r.t. x) of inside function, ax+b, and outside function, csc(x).

(ax+b)'=(ax)'+(b)'

(ax+b)'=a(x)'+0

(ax+b)'=a(1)+0

(ax+b)'=a

(csc(x))'=-csc(x)cot(x)

The chain rule states:

(f(g(x)))'=g'(x)×f'(g(x))

So our conclusion is:

(csc(ax+b))'=a×-csc(ax+b)cot(ax+b)

(csc(ax+b))'=-a csc(ax+b)cot(ax+b)

Answer:

She makes $1041 in 2 weeks

Step-by-step explanation:

First, we can work on finding how much she makes in a day. To find the daily income, we need to multiply 17.35 by 6 since she works 6 hours a day.

17.35x6=104.1

She makes $104.10 a day. Now we multiply by 5 since she works 5 days a week

104.10x5=520.50 a week

Since we are trying to find how much she makes in two weeks, we multiply the weekly income by 2

520.5x2=1041

She makes $1041 in 2 weeks

Answer:

1) El valor de los ocho helados de crema es 76,48 pesos, 2) El valor total de la compra es 85,97 pesos, 3) A Miguel le queda 13,59 pesos después de pagar en el supermercado.

Step-by-step explanation:

Supóngase que los costes son en pesos mexicanos. (MXN)

1) ¿Cuál es el valor de los ocho helados y que operación debe realizar?

Se multiplicar la cantidad de helados comprados por su valor unitario, es decir:

[tex]x = (8\,helados)\cdot \left(9,56\frac{MXN}{helado} \right)[/tex]

[tex]x = 76,48\,MXN[/tex]

El valor de los ocho helados de crema es 76,48 pesos.

2) ¿Cuál es el valor total que debe pagar en la tienda?

El valor total es la suma de todos los costes de los elementos comprados:

[tex]y = 76,48\,MXN + (1\,papa)\cdot \left(3,70\,\frac{MXN}{papa} \right)+(1\,gaseosa)\cdot \left(4,525\frac{MXN}{gaseosa} \right)+(1\,chocolatina)\cdot \left(1,267\,\frac{MXN}{chocolatina} \right)[/tex]

[tex]y = 85,97\,MXN[/tex]

El valor total de la compra es 85,97 pesos.

3) Si Miguel tiene en su bolsillo $99,56. ¿Cuánto dinero le queda después de pagar en el supermercado?

El remanente se obtiene al sustraer el valor total de la compra del efectivo disponible:

[tex]z = 99,56\,MXN-85,97\,MXN[/tex]

[tex]z = 13,59\,MXN[/tex]

A Miguel le queda 13,59 pesos después de pagar en el supermercado.

Answer:

2a) x=40.44, y=2.816

Step-by-step explanation:

2a)

Use SOHCAHTOA. You have the opposite (2.4) and the hypotenuse (3.7)

so you use SOH, which means sin(x) = opposite/hypotenuse

so x = sin⁻¹ (2.4 / 3.7) ≈ 40.44.

To find y, we use, CAH: cos(x) = y / hypotenuse

y = cos(x) * hypotenuse = cos(40.439793) * 3.7 ≈ 2.816

============================================

Work Shown:

x = price of one jump rope before the discount

x-1.80 = price of one jump rope after discount

2*(x-1.80) = total amount Gavin spends

2*(x - 1.80) = 14.38

x - 1.80 = 14.38/2 .... divide both sides by 2

x - 1.80 = 7.19

x = 7.19 + 1.80 ..... adding 1.80 to both sides

x = 8.99

Before the sale, one jump rope costs 8.99 dollars

After the sale, one jump rope costs 8.99 - 1.80 = 7.19 dollars.

This doubles to 2*7.19 = 14.38 dollars which is what Gavin spent in total. This helps confirm the answer.

$8.99

<EBF = 33°

<EBD = 33°

<FED = 114°

<FBD = 66°

Part 2

The value of y is either of 70 or -80. But then, we all know that speed can not be negative, so the speed was 70 km/h

The return speed is y + 10 = 70 + 10 = 80 km/h

Total time = 350/70 + 350/(70+10)

Total time = 5 + 4.375

Total time = 9.375 hr

Answer:

8) Real; Rational

9) Real; Rational; Integer; Whole; Natural

10) Real; Rational

Step-by-step explanation:

Real numbers consists of the subsets:

Irrational Numbers:

Irrational numbers is the subset complementary to rational numbers. It includes numbers such as √(2) or π. These numbers do not repeat nor terminate.

Rational Numbers:

Rational numbers are all the others. They include the integers as well as the repeating and terminating decimals.

Integers:

Integers include the entire set of whole numbers and the negative numbers. This subset does not include decimals nor fractions. Thus, the integers are: ...-3, -2, -1, 0, 1, 2, 3... etc.

Whole Numbers:

Whole numbers is the set of natural numbers that includes 0. So, whole numbers are: 0, 1, 2, 3... and so on.

Natural Numbers:

Natural numbers or the counting numbers are all the positive, non-decimal numbers. These are 1, 2, 3... and so on. This set does not include 0.

8) [tex]1.\overline{3}=1.3333...[/tex]

The given number is not natural, whole, nor an integer because it is a decimal. It repeats, so it belongs to the rational numbers subset.

9) [tex]\sqrt4=2[/tex]

The square root of 4 is simply 2. 2 is a natural number. Because of this, this means that 2 is also a whole number, integer, and a rational number.

10)[tex]-3/4=-0.75[/tex]

The given number is a fraction and it does not reduce to a whole number, so it's not a natural number, whole number, nor an integer. It does terminate, so it belongs to the rational numbers subset.

Answer:

  50 minutes

Step-by-step explanation:

The rate is the same, so the time is proportional to the distance:

  time to Houston = (65 min)(190/248) ≈ 49.8 min ≈ 50 min

It would take Jane 50 minutes to fly 190 miles.

Answer:

[tex]\Large \boxed{\mathrm{see \ below}}[/tex]

Step-by-step explanation:

Given.

(4x)/7 - 6 = -20

The x variable should be isolated on one side of the equation.

Adding 6 to both sides of the equation.

(4x)/7 - 6 + 6 = - 20 + 6

(4x)/7 = - 14

Multiplying both sides of the equation by 7.

(4x)/7 × (7) = - 14 × (7)

4x = - 98

Dividing both sides of the equation by 4.

(4x)/4 = - 98/4

x = - 24.5

Answer:

  g(-5) = 15

  g(-5) = 15

Answer:

centre = (6, - 2 )

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 6)² + (y + 2)² = 9 ← is in standard form

with (h, k ) = (6, - 2 ) ← centre

Answer:

Correlation

Step-by-step explanation:

The Simple linear regression model, also called as 'Classical Linear Regression Model' requires that X-Y data has a linear relationship.

Preliminary correlation analysis can be used to determine if data have this type of relationship. As Correlation is used to study positive or negative linear relationship between two variables.

However, difference is that Regression establishes cause effect relationship, correlation signifies just mutual correlation.
