Given the following system of equations:
kompoz [17]

Answer:

(D) Divide the first equation, -4x + 8y = 16 , by 2.

Step-by-step explanation:

Given:

-4x + 8y = 16 \ \ \ \ equation \ 1

2x + 4y = 8 \ \ \ \ equation \ 2

We need to find the operation performed on equation so as to get resultant equation as:

-2x + 4y = 8

2x + 4y = 8

From Above we can see that there is no change in equation 2 with respect to resultant equation.

Also Resultant equation is simplified form of equation 1.

Simplifying equation 1 we get;

-4x + 8y = 16

We can see that 2 is the common multiple on both side.

Hence we will divide equation 1 with 2 we get

\frac{-4x}{2}+\frac{8y}{2}=\frac{16}{2}\\\\-2x+4y=8

which is the resultant equation.

Hence (D) Divide the first equation, -4x + 8y = 16 , by 2 is the correct option.

7- a. What is the radius of the circle with center (3,10) that passes through (12,12)?
loris [4]

Answer: a. Radius of circle = \sqrt{85}

b. The equation of this circle : (x-3)^2+(y-10)^2=85

Step-by-step explanation:

Given : Center of the circle = (3,10)

Circle is passing through (12,12).

a. To find the radius we apply distance formula (∵ Radius is the distance from center to any point ion the circle.)

Radius of circle = \sqrt{(12-3)^2+(12-10)^2}

Radius of circle = \sqrt{(9)^2+(2)^2}=\sqrt{81+4}=\sqrt{85}

i.e. Radius of circle = \sqrt{85}

b. Equation of a circle = (x-h)^2+(y-k)^2=r^2 , where (h,k)=Center and r=radius of the circle.

Put the values of (h,k)= (3,10) and r= \sqrt{85} , we get

(x-3)^2+(y-10)^2=(\sqrt{85})^2

(x-3)^2+(y-10)^2=85

∴  The equation of this circle :(x-3)^2+(y-10)^2=85

Help i need to finish it today And can you explain the steps so i wont need help next time or if you don’t want to its okay :)
romanna [79]

Answer:

110 feet

Step-by-step explanation:

The formula to find the area of a rectangular prism is A = 2 (wl + hl + hw)

Substitute the values:

A = 2 (5x5 + 3x5 + 3x5)

A = 2 (25 + 15 + 15)

A = 2 (25 + 15 + 15)

A = 2 (55)

A = 110
