Using point-slope form, write the equation of the line that passes through the point (-1/2,1/2) and has a slope of -1

Answers

Answer 1

Answer:

y - 1/2 = -(x + 1/2)

Step-by-step explanation:

Use point slope form, y - y1 = m(x - x1), where (x1, y1) is a point on the line

Plug in the point given and the slope:

y - y1 = m(x - x1)

y - 1/2 = -(x + 1/2)

So, the equation is y - 1/2 = -(x + 1/2)

Answer 2

Answer:

y - 1/2 = -(x + 1/2)

2-2=-1(1+1)

Step-by-step explanation:

slope is given

y-y1=m(x-x1)

3/4 of girls in sss1 play basketball and 4/7 play volleyball. Every girl plays at least one of these games. if 27 play both games how many girls are in the class​

Answers

Answer:

84

Step-by-step explanation:

1/4 of class don't play basketball but do play volleyball

so 9/28 of class play both since 4/7 - 1/4 = 9/28

9/28 of class = 27

1/28 of class = 3

class = 3*28

There are 84 girls in the class.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Girls who plays basketball = (3/4)x

Girls who plays volleyball = (4/7)x

Girls who plays both games = 27

Now, Let us consider total girls in the class = x

So we can write it as mathematical equation as;

⇒ (3/4)x +(4/7)x - 27 = x

By taking L.C.M. -

⇒ (21x+16x)/28 - (27) = x

⇒ 37x/28 = x + 27

⇒ 37x = 28x + (27×28)

⇒ 9x = 27×28

⇒ x = (27×28)/9

⇒ x = 3×28

⇒ x = 84

So, There are total 84 girls in the class.

Answers

Answer:

The slope of line is 9

Step-by-step explanation:

We can use two pairs of input-output from the table to find the slope of the given line. Here x is input and y is output.

Slope is defined as the steepness of a line and is given by the formula:

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

Selected pairs from table are:

(-1,-18) and (0,-9)

Here

[tex]x_1 = -1\\x_2 = 0\\y_1 = -18\\y_2 = -9[/tex]

Putting the values in the formula

[tex]m = \frac{-9-(-18)}{0-(-1)}\\=\frac{-9+18}{0+1}\\= 9[/tex]

Hence,

The slope of line is 9

-5x + y = -6

7x + 2y = 39

Answers

Answer:

x=3, y=9

Step-by-step explanation:

Mulriplying the first equation by 2 yields -10x+2y=-12.

Subtracting the second equation from this gives -17x=-51, and thus x=3.

Substituting this back into the first equation gives -15+y=-6, and thus y=9.

Q.23 Prove that: (sin4A - cos4A + 1) = 2sin2A

Answers

Answer:

Step-by-step explanation:

I think you have the question incomplete, and that this is the complete question

sin^4a + cos^4a = 1 - 2sin^2a.cos^2a

To do this, we can start my mirroring the equation.

x² + y² = (x + y)² - 2xy,

This helps us break down the power from 4 to 2, so that we have

(sin²a)² + (cos²a)² = (sin²a + cos²a) ² - 2(sin²a) (cos²a)

Recall from identity that

Sin²Φ + cos²Φ = 1, so therefore

(sin²a)² + (cos²a)² = 1² - 2(sin²a) (cos²a)

On expanding the power and the brackets, we find that we have the equation proved.

sin^4a + cos^4a = 1 - 2sin^2a.cos^2a

Answers

Answer: B) 18

Step-by-step explanation: It is also widely used for predicting the value of one dependent variable from the values of two or more independent variables. When there are two or more independent variables, it is called multiple regression

The number of independent variables or predictors present in the regression model is 3.

The number of independent variables can be obtained from an ANOVA table of the degree of freedom column of corresponding to Regression

The Regression degree of Freedom usually denoted as k - 1 ; where k is the number of independent variables.

From the ANOVA table given ; k - 1 = 2

The value of k = 2 + 1 = 3 ; Therefore, the value of k in the regression table is 3.

Therefore, the number of predictors in the regression is 3.
