[tex]y = -\frac{1}{2}x - 1[/tex]

Step-by-step explanation:

Let's pick two points on the line: [tex]P_1(-4, 1)[/tex] and [tex]P_2(2, -2).[/tex] Let's calculate the slope of this line using these points:

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}[/tex]

With this value of the slope, we can write the general slope-intercept form of the equation as

[tex]y = -\frac{1}{2}x + b[/tex]

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

[tex]-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1[/tex]

Therefore, the slope-intercept form of the equation is

[tex]y = -\frac{1}{2}x - 1[/tex]

Step-by-step explanation:

a. -6, -9, 12

b. t(n) = 0.5 - 6

Answer:

C. 11

Step-by-step explanation:

This can be rewritten as

23 - 12

This is equal to 11.

Answer:

11

Step-by-step explanation:

-12 + 23 = 11

since the 12 is negative subtract it from 23 and you get 11 as your answer

Step-by-step explanation:

Triangle KLN has 3 equal angles so all sides of it must be equal ( equilateral triangle)

y+3=10

y=7

Triangle LNM has 2 equal angles as in an isosceles triangle so LN= ML

So sides opposite to equal angles must be equal too

x-6=y+3

x-6= 10

x= 16

Answer:

x = 12

y = 0

Step-by-step explanation:

Sum them:

2x = 24

so x = 12

12 - y = 12

so y = 0

Answer:

B. y = 58

Step-by-step explanation:

b) y=58 you follow the instructions

...............................................................................................................................................

The given quadratic function is      

y= 2x^2 - 2x - 2

We have to find the value of the function y at x=6.

Substitute x=6 in the given function.      

y= 2(6)^2 - 2(6) - 2

y= 2(36) - 12 - 2

y= 72 - 14

y= 58

The value of the function is 58 at x=6 is 58.

Therefore the correct option is B.

Answer: 10

Explanation:

(30)-(30)= 0

Singular matrices must equal 0

(Correct on my quiz)

The value of x would make the following matrix singular is 10

For a matrix to be singular, the determinant of the matrix must be zero.

For the given 2 by 2 matrix, for the matrix to be a singular matrix then, its determinant must be zero as shown;

(5* 6) - (3 * x) = 0

30 - 3x = 0

3x = 30

x = 10

Hence the value of x would make the following matrix singular is 10

(3)1. Find the coordinates of all points where the lines

x + y = 8, y = 5, and x = 1 intersect.

Step-by-step explanation:

this answer

The coordinates of all points where the lines x + y = 8, y = 5, and x = 1 intersect are (0, 5), (1, 0), (3, 5) and (1, 7).

Given that;

The equation of lines is,

x + y = 8

y = 5

x = 1

Now all the coordinates of all points where the lines x + y = 8, y = 5, and x = 1 intersect are find as,

x + y = 8

Put y = 5;

x + 5 = 8

x = 8 - 5

x = 3

Put x = 1;

1 + y = 8

y = 8 - 1

y = 7

Therefore, the points are (0, 5), (1, 0), (3, 5) and (1, 7).

Answer:

C = 50°

Step-by-step explanation:

In the given figure, it tells us which angles are the same. ( You can look at the red marks. )

So, 68 + 62 = 130.

As we all know, the sum of all angles in any triangle is 180.

So, 180 - 130 = 50.

That is Angle C.

Answer:

a. = 36km

b. Perimeter = 108km

c. Area = 486km^2

Step-by-step explanation:

Pythagoras theorem

a^2 + b^2 = c^2

27^2 + b^2 = 45^2

b^2 = 45^2 - 27^2

b^2 = 1296

b = [tex]\sqrt{1296}[/tex]

b = 36km

Perimeter

a + b + c

27 + 36 + 45 = 108

Perimeter = 108km

Area = [tex]\frac{ab}{2}[/tex]

Area = [tex]\frac{27 * 36}{2}[/tex]

Area = [tex]\frac{972}{2}[/tex]

Area = 486km^2
