Solve the system of equations algebraically.
lubasha [3.4K]

Answer:

Option (d) is correct.

(1, 0) is the solution of the given system of equation.

Step-by-step explanation:

Consider the given system of equation

4x - 2y = 4    ........(1)

6x - 4y = 6   ........(2)

We have to solve the system algebraically ,

We will solve it by elimination method,

Multiply equation (1) by 2, we get,

(1) ⇒ 8x - 4y = 8        ............(3)

Subtract equation (2) from (3) , we get,

8x - 4y - (6x - 4y) = 8 - 6

8x - 4y - 6x + 4y = 2

8x - 6x = 2

⇒ x = 1

Substitute x = 1 in (1) and solve for y , we get,

⇒ 4x - 2y = 4 ⇒ 4 (1) - 2y = 4 ⇒ 2y = 4 - 4  ⇒ 2y = 0 ⇒ y = 0

Thus,  (1, 0) is the solution of the given system of equation.

Option (d) is correct.

What is the best approximation of the surface area of this right cone
Tatiana [17]
Use the formula for the surface area of a right cone:

\sf A=\pi rs+\pi r^2

Where 'r' is the radius and 's' is the slant height, plug in what we know(use 3.14 to approximate for pi):

\sf A=(3.14)(12)(15)+(3.14)(12)^2

Multiply and simplify exponent:

\sf A=565.2+(3.14)(144)

Multiply:

\sf A=565.2+452.16

Add, round to the nearest whole number:

\boxed{\sf A\approx 1017~cm^2}
