If the point with coordinate
(k,7) lies on the equation 2x−y=5 determine the value of k


Answers

Answer 1

Answer:

k = 6

Step-by-step explanation:

since (k, 7 ) lies on the line then it satisfies the equation.

substitute the coordinates of the point into the equation and solve for k

2k - 7 = 5 ( add 7 to both sides )

2k = 12 ( divide both sides by 2 )

k = 6

Answer 2

Answer:

k = 6

Step-by-step explanation:

The point (k, 7) lies on the line with the equation 2x - y = 5

Substitute the coordinates of the point in the equation2(k) - 7 = 52k = 12k = 6

To solve the equation x ^2 - 2x = 3 by the technique of completing the square, you would add 4 to each side of the equation as one of the steps to reaching the solution.

Answers

Answer:

x = -1

x = 3

Step-by-step explanation:

[tex]\sf x^2 - 2x = 3[/tex]

Add 1 to both sides:

[tex]\sf \implies x^2 - 2x+1 = 3+1[/tex]

Factor the left side:

[tex]\sf \implies (x-1)^2 = 4[/tex]

Square root both sides:

[tex]\sf \implies x-1 = \pm2[/tex]

Therefore:

[tex]\sf \implies x-1=-2 \implies x=-1[/tex]

[tex]\sf \implies x-1=2 \implies x=3[/tex]

Now, we can work out the right hand side.

find f(-1) → f(-1) = -1³ which is -1then, find g(-1) → g(-1) = -1 - 1 = -2

Finally we can work out the full sum: 1 + -2 = -1.

3(x) + 13 = 5(x) + 93(x) - 5(x) = 9 - 13-2(x) = -4x = 2

Then find m∠A

3(x) + 13°3(2) + 13°6° + 13°19°

Answer:

19°

That's your answer

Step-by-step explanation:

So In this problem We are told both angles are vertical. That is enough information. When 2 Angles are vertical they measure the same. Vertical angles have SAME measure.

Now we are given 2 angles.

Angle A and Angle B

Angle A= (3x+13) degrees

Angle B=(5x+9) degrees

Knowing that and that they measure the same just put them equal to each other……

3x+13=5x+9

Given the equation just solve…..

Lets subtract 9 from 13

Then Subtract 3x

Then Divide by 4

3x+13=5x+9

3x+4=5x

4=2x

x=4/2 =2

x= 2

We now Know X is equal to ½ but we still need to figure out the measure of angle A

Angle A= 3x+13

So just plug in

3(2) +13= 19° :)

What is a circle?

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The angle formed by two secants (lines cutting a circle at two places) intersecting outside the ring is half the distance between their arc minus the closest arc.

From the diagram, the equation is given as,

∠A = (arc DE - arc BC) / 2

∠A = (94° - 70°) / 2

∠A = 24° / 2

∠A = 12°

The measure of the angle ∠A will be 12°. Then the correct option is B.
