The points (6,r) and (9, 9) lie on a line with slope 5. Find the missing coordinate r.

Answers

Answer 1

Answer:

r = -6

Step-by-step explanation:

Use the slope formula and solve for r.

slope = y2 -y1

            x2 -x1

Since you know all the numbers except for r, plug everything in and you get:

5  = 9 - r

        9 - 6

So then do the arithmetic, you find that 9 - r = 15. So r must = -6.

Step-by-step explanation:

In order to map the trapezoid onto itself, reflect the trapezoid over the x-axis, then rotate trapezoid by 180° in counterclockwise about the origin.

For the image of a figure to overlap with itself, the amount by which the figure should be rotated is?

For the image of a figure to overlap with itself, the figure should be rotated by 360°

We have a trapezoid as shown in the image.

In order to map the trapezoid onto itself -

Reflect the trapezoid over [x] axis.Now, rotate it counter - clockwise by 180 degrees

Therefore, in order to map the trapezoid onto itself, reflect the trapezoid over the x-axis, then rotate trapezoid by 180° in counterclockwise about the origin.

What are the coordinates of the vertex for f(x) = x2 + 4x + 10? (1 point) (−2, 2) (2, 2) (−2, 6) (2, 6)

Answers

You have to complete the square to get it into vertex form. Do this by setting the function equal to zero and at the same time moving the constant over to the other side of the equals sign so you have this: . Now we can complete the square on the polynomial by taking half the linear term, squaring it, and adding it to both sides. Our linear term is 4. Half of 4 is 2, and 2 squared is 4, so we add 4 to both sides: and simplify to get . In this process we have created a perfect square binomial on the left, which happens to be . Now move the -6 back over by addition to get . The vertex is found at (-2, 6), the third choice down.

You spent $173.20 buying three games at Best Buy along with a set of earpods that cost $37.00. If g is the cost of the game, and the equation representing the purchase is: 3g + 37 = 173.20 What is the cost of the game?

Answers

Answer:

$45.40

Step-by-step explanation:

3g + 37 = 173.20

3g + 37 -37 = 173.20 - 37

3g = 136.20

3g/3 = 136.30/3
