Answers

Answer:

Your wrong

Step-by-step explanation:

It's 6 x 1/2 = 6/2 which equals 3

Count each segment that ends at 3 which would give you 6 and 6 times 1/2 is 6/2 and 6/2 simplified is 3

3 is where it stops on the ruler so thats how I know correct.

It's 6 x 1/2 = 6/2 which also equals 3

In your own words, explain independent and dependent variables

Answers

independent variables don’t rely on another variable to work. dependent variables depend on another variable.

an independent variable is a variable(often used as x) whose variation does not depend on another variable. a dependent variable is the opposite, its’ variation depends on another variable.

Answer:

Look that the coordinates and trace those points to a corresponding number on the x or y axis. Then write the first number in the coordinate in the x value and the second number for the y value, repeat the process for the rest of the points.

An example is (-3,2), if you see the point (-3,2) on your graph, plug in -3 for the x value and 2 for the y value (don't include this example into your response - it was just for you to see what I mean)

Answer:

Step-by-step explanation:

To Write an equation for a table using a graph each point on the coordinate plane. Draw a line through the plotted points. Then,find the y intercept(where the line crosses the Y-axis.)

The students in Ms. Douglas’ class worked so hard this year that she has planned a surprise, end-of -year trip for them to a local amusement park. The school principal allows Ms. Douglas to spend a budget of $500 on the trip.
So far she knows :
A coach bus costs $180 to transport them to and from the park.
Price of admission to the park is $15 per person

Part A : Write an inequality that describes that how many students Ms. Douglas can bring on the trip. Define the variable

Part B: Solve the inequality and explain the solution in the context o the problem

Answers

Answer:

Part A: 180+15x=500

B: x = 21.333 or 21

Step-by-step explanation:

So in part A since you have 500 to spend and 180 goes to the coach bus, you are left with $ 320 to spend on the students and when you divide 320 by 15, (since the tickets for admission are $15) you end up with 21.333, but since you cant bring .333 of a student on a trip you can bring 21 students, but you can buy 21.333 tickets.

Answer:
A) 15x+180 ≤ 500
B) 33 people can go on the trip to not exceed the budget.

Steps:

15x+180 ≤500
Subtract 180 from both sides

15x ≤ 500
Divide both sides by 15 to isolate x(make sure to flip the sign since you are multiplying)

x ≥ 33.333

Therefore, only 33 people can go on the trip to not exceed the budget.

This is the graph of a __function.
The y-intercept of the graph is the function value y=
The smallest positive x-intercept of the graph is located at x=
The greatest value of y is y=___, and it occurs when x=
For x between x = π and 2π, the function value y ___ 0

Answers

Answer:

1) Cos

2) 1

3) π

4) 1

5) y < 0

Step-by-step explanation:

Cos

The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.

The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.

Highest y value from graph is 1, and besides, for cos graphs, y≤1.

We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.

The graph is of a cos function. The y-intercept of the graph is the function value y=1. The smallest positive x-intercept of the graph is located at x=π. The greatest value of y is y=1, and it occurs when x=2π. For x between x = π and 2π, the function value y<0.

The point on the graph where it crosses the y-axis is known as the y-intercept. The y-intercept in this situation is zero since the graph crosses the y-axis at (0, 0).

The point at which the graph first crosses the x-axis at a positive value of x is known as the graph's smallest positive x-intercept. The graph in this instance crosses the x-axis at (x,0), making the smallest positive x-intercept.

The maximum value of the function is equal to the highest value of y. The greatest value of y in this situation is 1, and it happens when x = 2.

The function value y declines from 1 to 0 for x between x = and 2. You can observe this by examining the graph.
