Answer:

y = 1/6x + 2

Step-by-step explanation:

point: (-6, 1)

slope 1/6

Our standard equation can be in the slope-intercept form: y = mx + b

m is the slope, which we know if 1/6. Plug this into our equation.

y = 1/6x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the point (-6, 1). Plug in the x and y values into the x and y of the standard equation.

1 = 1/6(-6) + b

To find b, multiply the slope and the input of x(-6)

1 = -1 + b

Now, add 1 from both sides to isolate b.

2 = b

Plug this into your standard equation.

y = 1/6x + 2

This is your equation.

Hope this helps!

Answer:

Area= 70x^3y^2

Perimeter = 20x^2 + 14 xy^2

Step-by-step explanation:

Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 .  The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.

Answer:

3/29

Step-by-step explanation:

area of total rectangle is 12x8 or 96 sq cm

area of shaded square is 9

96 - 9 = 87 sq cm, which is area of unshaded region

9 out of 87 is the probability of selecting a point in the shaded region, which simplifies to 3/29

Answer:

lol i see r o b l o x

Step-by-step explanation:

Rectangle = bxh

thats is 96

the we know that the square in the middle is 3x3x3x3 or 81

then subtract the two which is 15

The function g(x) is a discrete function. It is continuous between -7 to -2, -2 to 3, and 3 to 8. And the open circle at -7, -2, 3, and 8. And the jump of the g(x) is 4 units after every interval.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Bentley had 17 pencils. Kerry

had 32 pencils. How many

more pencils does Kerry have

than Bentley?

Number of pencils Bentley had = 17 pencils.

Number of pencils Karry had = 32 pencils.

Number of pencils Karry have more than Bentley = 32 - 17 = 15

Karry have 15 pencils more than Bentley.

Step-by-step explanation:

The equations of the corresponding circles can be any equation only have to satisfy the  general equation for  circle .

A circle is the set of all points in a plane at a given distance (called the radius ) from a given point (called the center.)

We know that the general equation for a circle is

[tex]( x - h )^2 + ( y - k )^2 = r^2[/tex],

where ( h, k ) is the center and r is the radius.

According to the question

The equation of circle given is

[tex]x^{2} + y^{2} = 1[/tex]

Center at origin

i.e

(h,k) = (0,0)

and radius = 1 unit

Now ,

By changing changing center (h,k) and radius of equation it will give following equations

h                      k                       r                            equation of circle

0                       1                       3                        [tex]( x - 0 )^2 + ( y - 1 )^2 = 3^2[/tex]

2                       2                       3                        [tex]( x - 2 )^2 + ( y - 2)^2 = 3^2[/tex]

1                        1                        1                         [tex]( x - 1 )^2 + ( y - 1 )^2 = 1^2[/tex]

-2                      -1                       2                        [tex]( x +2 )^2 + ( y + 1 )^2 = 2^2[/tex]

3                       2                       1                         [tex]( x - 3 )^2 + ( y - 2 )^2 = 1^2[/tex]

-5                      1                        3                        [tex]( x +5 )^2 + ( y - 1 )^2 = 3^2[/tex]

Hence, the equations of the corresponding circles can be any equation only have to satisfy the  general equation for  circle .
