Solve the system y=x-3 y=-2x+3

Answers

Answer 1

Answer:

x = 2, y= -1 Or (2, -1)

Step-by-step explanation:

Let’s solve the system using substitution. First we can set the equations equal to each other:

x-3= -2x +3

Now solve for x

3x-3= 3

3x = 6

x=2

Now that we have x, we can plug it back into one of the original equations to get y

y= x-3

y= 2-3

y = -1

Finally, the solution to the system of equations is (2, -1).

Solve The System Y=x-3 Y=-2x+3
Answer 2

Answer:

(2,-1)

Step-by-step explanation:

1.) y = x - 3

    y = -2x + 3

2.) Multiply top equation by 2

    2y = 2x - 6

    y = -2x + 3

3.) Add equations

    3y = -3

4.) Divide 3 from each side

     y = -1

5.) Substitute -1 for y in second equation

    -1 = -2x + 3

6.) Solve

     -4 = -2x

     x = 2

Therefore, (2, -1)

Answers

Answer:

C

Step-by-step explanation:

the range is all the possible numbers on the Y axis. We can see that the graphs peaks at 3 and then goes down both ways. This means that eventually the y axis will be equal to all real numbers less than 3

The range of the function looks to be all real numbers less than or equal to -1, according to the provided graph. The best choice is B.

What is a range of a function?

This is due to the fact that the graph's horizontal line at y=-1, which shows that the function accepts all values less than or equal to -1, stretches eternally in both directions.

The collection of all potential output values that a function can take on is generally referred to as the function's range. You can look at the vertical spread of the graph to see what values the function can take on in order to determine the range of a function from its graph.

Observe that the accompanying graph features a horizontal line at y=-1 that spreads out infinity in both directions. This indicates that for all values of x, the function takes on the value of -1.

The graph also features a vertical line at x=2 that goes on forever in both directions, as can be seen. This shows that the function can accept any value of y for x=2.

Combining these findings, we can determine that the function has a range of all real numbers less than or equal to -1 since it takes on the value of -1 for all x and the range of potential values of y is unrestricted.

What is diameter of circle?

"A diameter of a circle is the straight line that from one side of a circle to other side and passes through the center."

For given question,

The line segment connecting the two points B(-4,4) and D (10,4) is a diameter of the circle.

This means, the midpoint of the diameter BD would be the center of a circle G.

Let M represents the center of the circle.

First we find the coordinates of the center of the circle.

Using midpoint formula,

⇒ M = [tex](\frac{-4+10}{2} ,\frac{4+4}{2} )[/tex]

⇒ M = (6/2 , 8/2)

⇒ M = [tex](3,4)[/tex]

Now, we find the distance between points B(-4,4) and D (10,4) to determine the diameter of a circle G.

Using distance formula,

⇒ [tex]d=\sqrt{(4-4)^{2} +(10-(-4))^{2} }[/tex]

⇒ [tex]d=\sqrt{0+(14)^{2} }[/tex]

⇒ [tex]d=14[/tex] units

So, the radius of the circle r would be,

r = d/2

⇒ r = 14 / 2

⇒ r = 7 units

Now, we find the equation of circle with center M(3, 4) and radius r = 7 units.

Using center - radius form equation of circle would be,

[tex](x-3)^{2} + (y-4)^{2} = 7^{2}[/tex]

⇒ [tex]\bold{(x-3)^{2} + (y-4)^{2} = 49}[/tex]

Therefore, option (A) is the correct answer.

The solutions from least to greatest are lesser x = -2 and greater x = 2/3 for the equation (2x +4)(3x -2)=0

An equation is collection of two or more expressions with an Equal sign

The given equation is (2x +4)(3x -2)=0

To find the solutions, we set each factor equal to zero and solve for x

2x + 4 = 0

Subtract 4 from both sides

2x = -4

Divide both sides by 2

x = -2

Now 3x - 2 = 0

Add 2 on both sides

3x = 2

Divide both sides by 3

x = 2/3

Therefore, the solutions from least to greatest are lesser x = -2 and greater x = 2/3

Answer: n is greater than or equals to 1, where n is an integer

Step-by-step explanation:

The domain Abraham should use for s so it generates the sequence is n ≥ 1 where n is an integer option (C) is correct.

We have:

Abraham is writing a recursive function for the geometric sequence:

24, 12, 6,3,

The above sequence is a geometric progression.

The first term geometric progression is 24

s(1) = 24

s(n) = s(n-1)(1/2)

The nth term of the geometric progression:

The common ratio = 12/24 = 1/2

s(n) = s(n-1)(1/2)

n ≥ 1 where n is an integer.

Thus, the domain Abraham should use for s so it generates the sequence is n ≥ 1 where n is an integer option (C) is correct.
