Find the inequality represented by the graph.

Answers

Answer:

y > 1/3 x - 3

Step-by-step explanation:

First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).

Find the change of y over the change of x to get the slope of the line.

(-2 - (-3))/(3 - 0) = 1/3

Since the line intercepts the y axis at (0, -3), the equation of the line would be

y = 1/3x - 3

We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents

y > 1/3 x - 3

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

     = - 2(x + 3)² + 18 - 16

     = - 2(x + 3)² + 2 ; y = 2

A company is analyzing whether its employees prefer to skip their lunch break and leave a half-hour early each day or take a lunch break and
leave at the normal time each day. It conducts an observational study to determine which option is selected more often. At the end of the first
week, the company finds that the majority of employees prefer to skip their lunch break and leave a half-hour early each day.
The company then repeats the observational study for 10 more weeks. The study yields the same results for only five of the weeks. What
generalization can be made from the results of this study?
A.
The majority of employees prefer to take a lunch break and leave at the normal time each day.
В.
The sample is biased; therefore, a generalization cannot be made regarding which option is selected more often.
C.
The results are inconclusive; therefore a generalization cannot be made regarding which option is selected more often.
D.
The majority of employees prefer to skip their lunch break and leave a half-hour early.

Answers

Answer:

C. The results are inconclusive; therefore a generalization cannot be made regarding which option is selected more often.

explanation:

just took the test on plato

Since the study yields the same results for only five of the weeks. So here the generalization could be made like option c.

What type of generalization made?

Since at the closing of the first week the company determined the majority of the employees should prefer the lunch break and also the company repeats the observational study for 10 more weeks.

So here the output is to be inconclusive. Due to this, the generalization cannot be made with respect to the selection of the given options.

hence, the option c is correct.

Which conic section is represented by the following equation?

circle

Answers

Answer:

3 rd one

Step-by-step explanation:

The conic section represented by the given equation is Circle.

What is Circle?

Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.

Standard form of a circle is,

(x - h)² + (y - k)² = r²

where, (h, k) is the center of the circle and r is the radius of the circle.

Expanding, we get,

x² - 2hx + h² + y² - 2ky + k² = r²

x² - 2hx + y² - 2ky + (h² + k² - r²) = 0

The given equation is,

5x² – x + 5y² – 3y + 4 = 0

This is same as the standard form of the circle.

Hence the given equation is that of a circle.

3(2c + 5) = 39
What is the answer ?

Answers

Answer:

c=1

Step-by-step explanation:

Simplifying

3 + 2c = 5

Solving

3 + 2c = 5

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2c = 5 + -3

Combine like terms: 3 + -3 = 0

0 + 2c = 5 + -3

2c = 5 + -3

Combine like terms: 5 + -3 = 2

2c = 2

Divide each side by '2'.

c = 1

Simplifying

c = 1

It’s solving systems of equations

Answers

Answer:

7 quarters, 8 nickels

Step-by-step explanation:

So the system of equations you have is:

x + y = 15

0.25x + 0.05y = 2.15

Here's how to solve:

first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:

25x + 5y = 215

Then, you can divide both sides by 5 to simplify it more:

5x + y = 43

Now, you have the system of equations:

5x + y = 43

x + y = 15

Now subtract the two equations:

4x = 28

divide both sides by 4

x = 7

plug x = 7 into the equation x + y = 15 to solve for y:

7 + y = 15

subtract 7 from both sides

y = 8

So you know that there are 7 quarters and 8 nickels.
