Which ordered pairs make both inequalities true? Select two options. y < 5x + 2 y > One-halfx + 1 On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (negative 2, 0) and (0, 1). Everything above the line is shaded. The second dashed line has a positive slope and goes through (negative 1, negative 3) and (0, 2). Everything to the right of the line is shaded. (–1, 3) (0, 2) (1, 2) (2, –1) (2, 2)

Answers

Answer:

(1, 2)

(2,2)

Step-by-step explanation:

The inequality Given :

y < 5x + 2

y ≥ One-halfx + 1

We can use the values in the options to see which satisfies the inequality :

(-1, 3) ; X = - 1, y = 3

3 < 5(-1) + 2 ; 3 < - 4 (not true)

(0, 2) ; X = 0 ; y = 2

2 < 5(0) + 2 ; 2 < 2 (nor true)

2 > 1/2(0) + 1

2 > 1 (true)

Using (1, 2).; x = 1 ; y = 2

2 < 5(1) + 2 ; 2 < 7 (true)

2 > 1/2(1) + 1 ; 2 > 1.5 (true)

Using (2, 2)

y < 5x + 2

2 < 10 + 2 ; 2 < 12 (true)

y > 1/2x + 1

2 > 1/2(2) + 1 ; 2

Find the value of x in the triangle shown below

Answers

Answer:

x = 48°

Step-by-step explanation:

Two sides of the triangle are equal, both 7, Then the 2 base angles are congruent, both 66°

The sum of the 3 angles in the triangle sum to 180° , so

x = 180° - (66 + 66) = 180° - 132° = 48°

In order to obtain consistent estimators of 0 and 1, when x and u are correlated, a new variable z is introduced into the model which satisfies the following two conditions: Cov( z, x) 0 and Cov ( z, u) = 0. The variable z is called a(n) _____ variable. 答案选项组 dummy instrumental lagged dependent random

Answers

Answer:

Instrumental variable

Step-by-step explanation:

cov(z,u)  shows that the instrumental variable is exogenous. An instrumental variable can also be regarded as a third variable, It is included in the model if you have an issue of endogeneity in your regression model. An endogeneity problem arises if there are other variables are being influenced by other independent variable in the same regression model. we use z to account for these behaviours in the model. this variable controls for measurement errors as well as confounding errors.  

When 4 is added to three times of a number, the answer is the same as subtracting 2 from the number. What is the number ?

Answers

Answer:

- 3

Step-by-step explanation:

let n be the number , then

3n + 4 = n - 2 ( subtract n from both sides )

2n + 4 = - 2 ( subtract 4 from both sides )

2n = - 6 ( divide both sides by 2 )

n = - 3

The number is - 3

What is integer?

An integer is a whole number (not a fractional number) that can be positive, negative, or zero. All the whole numbers are also integers, because integers include all the positive and negative numbers.

Given that:

let n be the number , then

2n + 4 = - 2 ( subtract 4 from both sides )

2n = - 6 ( divide both sides by 2 )

n = - 3

these marbles are placed in a bag and two of them are randomly drawn. what is the probability of drawing two blue marbles if the first marble is placed back in the bag before the second draw

Answers

Answer:  1/4

In other words, the number 4 goes in the green box.

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

Explanation:

2 yellow + 3 pink + 5 blue = 10 total marbles

We have 5 blue out of 10 total, so 5/10 = 1/2 represents the probability of picking a blue marble.

Picking two marbles in a row is represented by the probability (1/2)*(1/2) = 1/4

The fraction 1/2 stays the same for both selections because we put the first marble back.

The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the

OA. Multiply the second equation by-3. The solution is x= 12, y=9.
OB. Multiply the second equation by -2. The solution is x = 12, y=10.
OC. Multiply the second equation by 2. The solution is x = 15, y = 9.
OD. Multiply the second equation by 3. The solution is x = 12, y = 10.

Answers

Answer:

Multiply the second equation by 3. The solution is x = 12, y = 10.

Step-by-step explanation:

The given equations are :

x+3y= 42 ....(1)

2x - y = 14 ...(2)

For elimination method,

Multiply the second equation by 3.

6x-3y=42 .....(3)

Adding equations (1) and (3).

x+3y+6x-3y=42+42

7x = 84

x = 12

Put the value of x in equation (1).

12+3y= 42

3y = 30

y = 10

So, x = 12 and y = 10. Hence, the correct option is (d).

7 th term and 14 th term of an Arithmetic sequence are 36 and 64 respectively , find the common difference and ,25th term

Answers

Answer:

(a) The common difference is 4

(b) The 25th term is 108

Step-by-step explanation:

Given

[tex]T_7 = 36[/tex]

[tex]T_{14} = 64[/tex]

Solving (a): The common difference

The nth term of an AP is:

[tex]T_n = a + (n -1)d[/tex]

For the 7th term, we have:

[tex]36 = a + (7 -1)d[/tex]

[tex]36 = a + 6d[/tex]

For the 14th term, we have:

[tex]64 =a + (14 -1)d[/tex]

[tex]64 =a + 13d[/tex]

Subtract both equations

[tex]64 - 36 = a - a +13d-6d[/tex]

[tex]28 = 7d[/tex]

Divide by 7

[tex]d = 4[/tex]

Solving (b): The 25th term

First, we calculate the first term (a)

The 7th term of the progression is:

[tex]36 = a + 6d[/tex]

Substitute [tex]d = 4[/tex]

[tex]36 = a + 6 * 4[/tex]

[tex]36 = a + 24[/tex]

Subtract 24

[tex]a = 36 -24[/tex]

[tex]a = 12[/tex]

The 25th term is:

[tex]T_{25} = a + (25 - 1)d[/tex]

[tex]T_{25} = 12 + (25 - 1)*4[/tex]

[tex]T_{25} = 12 + 24*4[/tex]

[tex]T_{25} = 108[/tex]

A parabola can be represented by the equation x2 = –20y.

Answers

Answer:

The requried coordinates of the focus of the parabola x² = -20y are (0, -2.5), which corresponds to the option (0, -5).

What is a parabola?

A parabola is a cross-section cut out of the cone and represented by an equation y = 4ax².

The standard form of the equation of a parabola is (y - k) = (1 / 4p)(x - h)², where (h, k) is the vertex and p is the distance from the vertex to the focus. We can convert the given equation x² = -20y into this standard form by completing the square:

x² = -20y

x² / (-20) = y

x² / (-20) + 0 = y + 0

(x - 0)² = -20(y - 0)

Comparing this equation to the standard form, we can see that the vertex is at (h, k) = (0, 0), and that 4p = -20, so p = -5/2.

Since the focus is a distance of p below the vertex, the focus is at (h, k - p) = (0, -5/2), which is the same as (0, -2.5).

Therefore, the coordinates of the focus of the parabola x² = -20y are (0, -2.5), which corresponds to the option (0, -5).

Find the slope of the line. Describe how one variable changes in relation to the other. How did you find this?
A, 2/3; the amount of water decreases by 2 gallons every 3 minutes.
B, - 2/3; the amount of water decreases by 2 gallons every 3 minutes.
C, - 3/2; the amount of water decreases by 3 gallons every 2 minutes.
D, -1; the amount of water decreases by 1 gallon per minute.

Answers

According to the given information, the slope of the line is -1.

What is slope ?

In mathematics, slope is a measure of how steep a line is, or how much y (vertical) changes for a given x (horizontal) change. It is represented by the letter "m" and is calculated as the change in y divided by the change in x, or rise over run. The slope can be positive, negative, zero, or undefined.

According to given information :

The answer is D, -1; the amount of water decreases by 1 gallon per minute.

To find the slope of the line, we need to use the slope formula:

slope = (change in y)/(change in x)

In this case, the change in y represents the change in the amount of water, and the change in x represents the change in time.

Option A says that the slope is 2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is incorrect because as time increases, the amount of water should decrease, so the slope should be negative.

Option B says that the slope is -2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is the same as option A but with a negative slope, which is correct because the amount of water decreases over time.

Option C says that the slope is -3/2, which means that for every 2 minutes, the amount of water decreases by 3 gallons. This is incorrect because the amount of water should decrease by the same amount every minute.

Option D says that the slope is -1, which means that for every minute, the amount of water decreases by 1 gallon. This is the correct answer because it describes a constant rate of change in the amount of water over time.

Therefore, according to the given information, the slope of the line is -1.
