Find the value of XA: 2B: 4C: 6D: 8​

Mathematics
1 answer:

3 0

Using the Pythagorean theorem:

x^2 + (x-2)^2 = (√20)^2

Simplify the right side:

x^2 + (x-2)^2 = 20

Subtract 20 from both sides:

x^2 + (x-2)^2 - 20 = 0

Factor:

(x-4)(x+2) = 0

Solve for each x:

x = 4 and x = -2

The side cant be a negative value, so the answer would be x = 4

The answer is B.

The answer would be (-2,10)

Explanation:
Since it is telling us to focus on point A, we should do so.

It tells us to shift -6 units horizontally. This means we should shift point A to the left 6 units.

Then it wants us to reflect over the x-axis. The x-axis is the horizontal line. Flipping it across just means changing the x value to the opposite.

Therefore it is (-2,10)

Find the solution set (x,y,z) of the system:<br> 3x-2y+4z=6<br> 2y-3z=20<br> 6z=12
gizmo_the_mogwai [7]

Answer:

The solution is x = 8, y = 13 and z = 2.

Step-by-step explanation:

We are given a system of equations with the variables x, y, and z from which we have to solve for x, y, and z.

The equations are

3x - 2y + 4z = 6 ........ (1)

2y - 3z = 20 .......... (2)

6z = 12 ......... (3)

Now, from equation (3),  we get z = 2.

Now, putting z = 2 in equation (2) we get

2y = 20 + 6 = 26  

⇒ y = 13

Now, from equation (1), putting y = 13 and z = 2, we get  

3x = 6 - (4 × 2) + (2 × 13) = 24

⇒ x = 8

So the solution is x = 8, y = 13 and z = 2. (Answer)

What is the equation of the line that passes through the point (5, -2) and has a<br> slope of -2/5
Alecsey [184]

Answer:

y=-2/5x

Step-by-step explanation:

y-y1=m(x-x1)

y-(-2)=-2/5(x-5)

y+2=-2/5(x-5)

y=-2/5x+10/5-2

y=-2/5x+2-2

y=-2/5x
