Answers

Answer 1

Answer:

6 miles per hour

Answer 2

Answer:

Step-by-step explanation:

Rate of change = Change in Y over Change in X

Delta Y = (6-0)=6

Delta X = (2-0) = 2

Rate of change = 6/2 =3 miles per hour

Answers

Answer:

hi my name is chelsea and i wiuld like ti thank yiu fir the points

Answer:

180 deg rotation

Step-by-step explanation:

You can't simply translate the original figure into its image. You'd need a reflection or a rotation. For example, if you reflected triangle HTY over the x-axis, and then reflected it over the y-axis, you'd get triangle H'T'Y. The problem does not allow for reflections, so this cannot be used. That means you must use a rotation.

Use the origin as the center of rotation.

Rotate triangle HTY 180 degrees clockwise or counterclockwise.

You end up with the image.

Answer: 180 deg rotation

Answers

ANSWER: 18

SOLUTION: if the ratio of chairs to tables is 6 to 1 and there are 3 tables in the room you just times 3 by six to get the amount of chairs.

The ratio of chairs to tables in the conference room is 6 to 1. For every table, there are 3 tables, then, the amount of chairs is 18.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The ratio of chairs to tables in the conference room is 6 to 1.

For every table, there are 3 tables,

if the ratio of chairs to tables is 6 : 1 and there are 3 tables in the room  

Then, the amount of chairs = 6 x 3

                                             = 18

The graph shows two lines, A and B.

A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. Another straight line labeled B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.


Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.


Part B: What is the solution to the equations of lines A and B? Explain your answer

Answers

Answer:

C(2, 2) is the solution to both lines A and B.

Step-by-step explanation:

Line A is given as:

A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6.

We know that the equation of a line passing through (a,b) and (c,d) is calculated as:

Hence, the equation of line is:

Hence, equation of line A is:

Similarly B is a line passing through (0,0) and (5,5).

Hence, the equation of line B is:

So, from the graph we observe that, the point of intersection of the two lines is (2,2).

Thus, option C is correct.

Tell whether the angles are adjacent or vertical. Then find the value of x.

Answers

Answer:

  x = 63°

Step-by-step explanation:

~ They are adjacent angles because they have a common (one) vertex.

~ To find the value of x we must make an equation.

Angles on a straight line add up to 180°.

  117 + x = 180

  x = 180 - 117

  x = 63°

Answer:

63

Step-by-step explanation:

Let's solve your equation step-by-step.

x2=−5x

Step 1: Subtract -5x from both sides.

x2−−5x=−5x−−5x

x2+5x=0
