Answer:

−6x−19y−56

Step-by-step explanation:

−8(2x)+5(2x−12)+−2(5y−2)+(−3)(3y)

Multiply −8 and 2 to get −16. Multiply −3 and 3 to get −9.

−16x+5(2x−12)−2(5y−2)−9y

Use the distributive property to multiply 5 by 2x−12.

−16x+10x−60−2(5y−2)−9y

Combine −16x and 10x to get −6x.

−6x−60−2(5y−2)−9y

Use the distributive property to multiply −2 by 5y−2.

−6x−60−10y+4−9y

Add −60 and 4 to get −56.

−6x−56−10y−9y

Combine −10y and −9y to get −19y.

−6x−56−19y

Answer:

-6x - 19y - 56

Step-by-step explanation:

<u>Simplify</u>:

-8(2x) + 5(2x - 12) + -2(5y - 2) + (-3) (3y) =
-16x + 10x - 60 - 10y + 4 - 9y =
x(-16 + 10) + y(-10 - 9) + (-60 + 4) =
x(-6) + y(-19) + (-56) =
-6x - 19y - 56

Answer:

Step-by-step explanation:

well the mean is adding all the numbers up and divide them by how many different numbers there are for example 7 9 18 41 9, first you would add them all together 41+18=59 59+(9+9) well 9+9=18 so 59+18=77 77+7=84 we're done with the First part, now we divide it by the number of different numbers that are shown, which is 5, so it's 84 divided by 5 which gives you the answer of 16.8

Help with this math problem plz

Aleks04 [339]

Answer:

A'(-3,3)

Step-by-step explanation:

Point A of the triangle is 2 units below the line. Therefore when refelected over the line, point A will be 2 units above the line. 2 units above the line, y=1, is 3.

Since the triangle is being reflected over y=1, the x coordinate will stay the same, but the y coordinate will change. (If the line was being reflected over x=1, then the y coordinate would stay and the x coordinate would change).

Therefore the new y coordinate will be 3, and the x coordinate will be the same as it was before, -3.

A circle is defined by the equation x2 + y2 – x – 2y – = 0. What are the coordinates for the center of the circle and the length

madreJ [45]

X^2 + y^2 - x - 2*y = 0
To find both coordinates and radius we need to make this equation in circle form:
(x-a)^2 + (y-b)^2 = r^2

x^2 - 2*1/2*x + 1/4 - 1/4 + y^2 - 2*1*y + 1 - 1 = 0
Here we are adding and subtracting numbers in order to get square binomial.
(x - 1/2)^2 + (y-1)^2 = 5/4

coordinates of center are (1/2,1) and the radius is √ $\frac{5}{4}$
