Answer:

4(x+2y) = 8y+4x

Step-by-step explanation:

because if you distribute the 4 to the x and y you will get 4x and 8y because you are multiplying the outside number with both first numbers in the parentheses for example

10(4x+y) = 40x+10y

What is 3/4 plus 1/3 equals?

snow_lady [41]

Answer:

1 1/12

Step-by-step explanation:

3/4 x 3/3

1/3x4/4

9/12+4/12=13/12

The fraction 13/12 Cannot be reduced, But the fraction 13/12 is the same as 13 divided by 12

So 13/12=1 1/12

Therefore 3/4+1/3=1 1/12

Write an equation for a circle with a diameter that has endpoints at (7, –4) and (1, –10). Round to the nearest tenth if necessa

Black_prince [1.1K]

The standard form for the equation of a circle is :

(x−h)^2+(y−k)^2=r2 ----------- EQ(1)
where handk are the x and y coordinates of the center of the circle and r is the radius.
The center of the circle is the midpoint of the diameter.

So the midpoint of the diameter with endpoints at (7,-4)and(1,-10) is :

((7+(1))/2,(-4+(-10))/2)=(4,-7)

So the point (4,-7) is the center of the circle.

Now, use the distance formula to find the radius of the circle:

r^2=(7−(4))^2+(-4−(-7))^2=9+9=18

⇒r=√18

Subtituting h=4, k=-7 and r=√18 into EQ(1) gives :

(x-4)^2+(y+7)^2=18
