Answer:

3/2, 1/2, - 1

Step-by-step explanation:

x + 2y = 1 --> this is 'f(x)'. Sub in the each x-value to the equations.

First part:

x = -2

x + 2y = 1

-2 + 2y = 1

2y = 3

y = 3/2

Second part:

x = 0

x + 2y = 1

0 + 2y = 1

2y = 1

y = 1/2

Third part:

x = 3

x + 2y = 1

3 + 2y = 1

2y = -2

y = -2/2

y = - 1

A bus travels at a constant speed of 48 km/h. How long will it take to travel 600 km?
grigory [225]

Answer:

It will take 12 and 30 hours

A survey with a two-point scale was conducted in an organization. It concluded that 85% of the respondents were unsatisfied with
Morgarella [4.7K]

Answer:

Number of the peoples were satisfied with the career guidance are 300 .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

A survey with a two-point scale was conducted in an organization.

It concluded that 85% of the respondents were unsatisfied with the career guidance they were provided.

If 2,000 people participated in the survey.

Total value = 2000

Percentage = 85%

Putting all the values in the formula

85 = \frac{Part\ value\times 100}{2000}

Part\ value= \frac{2000\times 85}{100}

Part\ value= \frac{170000}{100}

Part value = 1700

i.e

People not satisfied by the career guidance = 1700

People satisfied by the career guidance = Total people participated in survey  - People not satisfied by the career guidance .

Putting the values in the above

                                                                  = 2000 - 1700

                                                                  = 300

Therefore the number of the peoples were satisfied with the career guidance are 300 .

Write an equation that is parallel to y=-5/2x-5
NeX [460]

       A parallel equation (when graphed) will have the same slope, but a different y-intercept.

       As long as you keep y = -\frac{5}{2}x + b, you can input anything for b to solve this question.

       Given:

y = -\frac{5}{2}x - 5

       Equation of a parallel line:

y = -\frac{5}{2}x + 6, y = -\frac{5}{2}x + 1,356, y = -\frac{5}{2}x - 8, etc

     Example answer you can use:

             y = -\frac{5}{2}x - 8
