2x+4y=12 y=0.25x-3 What is the solution to the system of equations?

ololo11 [35]

{ 2 x + 4 y = 12
y = 0.25 x -3

Arrange equation variables of elimination :

{ 2 x + 4 y = 12
-0.25 x + y = - 3

Multiply ( -0.25 x +y = - 3 ) by 8 :

8y - 2 x = - 24

{ 2 x + 4y = 12
-2x + 8y = -24
----------------------
12 y = -12

y = - 12 / 12

y = - 1

For x :

2 x + 4y = 12

2 x + 4 ( - 1 ) = 12

2 x - 4 = 12

2 x = 12 + 4

2 x = 16

x = 16 / 2

x = 8

x = 8 and y = - 1 => ( 8 , - 1 )

Answer b

hope this helps!

Can the set of lengths be the side lengths of a right triangle?

andreyandreev [35.5K]

Answer:

B. No.

Step-by-step explanation:

We have been given 3 side lengths 7 ft, 12 ft, 17 ft. We are asked to determine, whether the given set of lengths can form a right triangle or not.

We will use Pythagoras theorem to solve our given problem, which states that the square of hypotenuse of a right triangle is equal to the sum of squares of two legs of right triangle.

$17^2=12^2+7^2$

$289=144+49$

$289>193$

Since the sum of squares of both legs is less than square of hypotenuse, therefore, the given set of lengths can not be the side lengths of a right triangle.

Express the -0.345 in the form of p\q and reduce it to the lowest term

Mamont248 [21]

Answer:

-69/200

Step-by-step explanation:

-0.345 is in decimal form.

In Fractional form (p/q)

=-345/1000

To simplify, divide the numerator and the denominator by the G.C.D(Greatest Common Divisor) of p and q.
