Answer:

The coordinates of the other points are (7,8)

Step-by-step explanation:

Mathematically, we have the midpoint formula as;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

(1,1) = (-5 + x2)/2 , (-6 + y2)/2

-5 + x2 = 2(1)

x2 = 2 + 5 = 7

(-6 + y2) = 2(1)

-6 + y2 = 2

y2 = 2 + 6

y2 = 8

The coordinates of the other points are (7,8)

Answer:

X= -1/6

Step-by-step explanation:

Answer:

x=-1/6

Alternate form

x=-0.16, x=6^-1

Step-by-step explanation:

3(4-x)=13+3x

Distribute 3 through the parentheses

12-3x=13+3x

Move the variable to the left-hand side and change its sign

12-3x-3x=13

-3x-3x=13-12

collect like terms

-6x=13-12

-6x=1

Divide both sides of the eqation by -6

x=-1/6

Alternate form

x=-0.16, x=6^-1

Answer:

71

Step-by-step explanation:

No you do 128 + 90= 218

then you do 360 - 218=142

142 divide by 2 = 71

Answer:

A = 25x^2 + 30x + 9

Step-by-step explanation:

A = (5x+3) * (5x+3) or A = (5x+3)^2

A = 5x*5x + 5x*3 + 5x*3 + 3*3

A = 25x^2 + 15x + 15x + 9

A = 25x^2 + 30x + 9

Answer:

309in²

Step-by-step explanation:

Area of an octagon is expressed as;

A=2(1+√2)a²

a is the side length of the octagon

Given

a = 8

Substitute into the formula

A = 2(1+√2)(8)²

A = 2(1+√2)(64)

Expand

A = 2(64+64√2)

A = 128+128√2

A = 128+128(1.414)

A = 128+181.01

A = 309in²

Hence the area of the octagon is 309in²

Answer:

the slope of the line is undefined, and the equation is x = -4

Step-by-step explanation:

The slope of a vertical line is undefined .

What is slope with example?

given ,

          the point ( -4 , 3 )

                  x = -4 , y = 3

A line perpendicular to the x-axis is generally described by the equation x=a, where an is a real number. It is also known as a vertical line.

This line equation is x= -4 because you are seeking for a vertical line that goes through the point (x, y)=(-4 , 3) in your diagram.

in this question we are finding equation of line which is perpendicular to x - axis .

but for the equation of line we need to slope , that is not given in this question  .

The slope of a vertical line is undefined .

Answer:

y=-6x-6 is the answer!

Step-by-step explanation:

12x+2y=-12

-12x       -12x

2y=-12x-12

divide all by 2, to simplify y

y=-6x-6

Answer:

write into slope intercept form, y=mx+b

y=-6x-6

Answer:

Total cost of the clothes = 4x + 2y

Total cost of the clothes = 2y + 4x

B. Total cost of the clothes = 6x + 4y

Total cost of the clothes = 4y + 6x

Step-by-step explanation:

Meredith bought 4 T-shirts and 2 pairs of pants. If x is the cost of one T-shirt and y is the cost of one pair of pants, she’ll have to multiply the number of T-shirts by x and the number of pants by y to find the total cost of the clothes.

Write an expression for finding the total cost of the clothes?

Apply the properties of operations to find an equivalent expression for finding the total cost of the clothes?

B. Write an expression for finding the total cost of the clothes if Meredith bought 6 T-shirts and 4 pairs of pants. Also write an equivalent expression for that expression?

Let

x = cost of one T-shirt

y = cost of one pair of pants,

Total cost of the clothes = 4x + 2y

Equivalent expression for finding the total cost of the clothes?

Switch the cost of T-shirt and cost of one pair of pants

Total cost of the clothes = 2y + 4x

B. Total cost of the clothes = 6x + 4y

Equivalent expression for finding the total cost of the clothes?

Total cost of the clothes = 4y + 6x

Explanation:

Remember the rules of logarithms:

log

log

(

. Using this, we get

log

(

⇒

log

(

x

=

Now we remember that

log

c

=

d

⇔

c

=

10

d

. Essentially what we're doing there is taking 10 to the power of both sides, and since

10

x

and

log

Answer:

149°

Step-by-step explanation:

let the remaining side of the triangle a,

now,

63°+86°+a=180°(sum of angles of a triangle)

149°+a=180°

a=180°-149°

a=51°

again,

x+a=180°(being linear pair)

x+51°=180°

x=180°-51°

•°•x=149°
