Use the subtraction method to solve the system of equations. Choose the correct ordered pair. 2x-y=6

Ber [7]

Answer:

Check for (3, 0)

Put x = 3 and y = 0 in equation 2x – y = 6

2(3) – (0) = 6

6 = 6

<h2>True statement. </h2>

(3,0) is a solution of 2x – y = 6.

(ii) Check for (0, 6)

Put x = 0 and y = 6 in 2x – y = 6

2 x 0 – 6 = 6-6 = 6

<h2>False statement. </h2>

⇒ (0, 6) is not a solution of 2x – y = 6.

(iii) Check for (2, -2)

Put x = 0 and y = 6 in 2x – y = 6

2 x 2 – (-2) = 6

4 + 2 = 6

6 = 6

<h2>True statement. </h2>

⇒ (2,-2) is a solution of 2x – y = 6.

(iv) Check for (√3, 0)

Put x = √3 and y = 0 in 2x – y = 6

2 x √3 – 0 = 6

2√3 = 6

<h2>False statement. </h2>

⇒(√3, 0) is not a solution of 2x – y = 6.

(v) Check for (1/2, -5)

Put x = 1/2 and y = -5 in 2x – y = 6

2 x (1/2) – (-5) = 6

1 + 5 = 6

6 = 6

<h2>True statement. </h2>

⇒ (1/2, -5) is a solution of 2x – y = 6.

When solving a quadratic equation using the quadratic formula, the value of the discriminant is 49. How many and what type of so

musickatia [10]

Answer: 2 rational solutions

Step-by-step explanation:

When the discriminant, b² + 2a, is greater than 0, there are two real solutions. 49 is the perfect square of 7, so the solutions are also rational: plus and minus 7

What is the y intercept of the function f(x)=2•3^x

kykrilka [37]

Answer:

$\boxed{Option \ A}$

Step-by-step explanation:

$f(x) = 2*3^x$

y intercept is when x = 0

So, Putting x = 0 in the above function

=> f(0) = $2*3^0$

=> f(0) = 2*1

=> f(0) = 2

So, y-intercept is (0,2)

Math Help Please....

rodikova [14]

Let's go through the answer choices one by one:

A. False. The line segment contains more than just the endpoints

B. False. There are points in this description that extend beyond the endpoints. If this was a line instead of a segment, then choice B would be the answer

C. True. This is the answer. Though your teacher should have added "collinear" to the sentence to make it clear that the points are between M and N, and also collinear to M and N. All of these points form the line segment MN

D. False. That would be the perpendicular bisector of MN

----------------------------------------------------------------------------------------------------

So once again, the final answer is choice C

Which of the following are the coordinates of the vertex of Y=3x2 + 3?

Lemur [1.5K]

Answer:

(0,3)

Step-by-step explanation:

y = 3x^2 +3

This is in the form

y = a(x-h)^2 +k

Where the vertex is (h,k)

y = 3(x-0)^2 +3

The vertex is (0,3)
