Need help ASAP BC it’s too hard for me

Answers

Answer 1

Answer:

1=3

Step-by-step explanation:

Subtract the number without the x from the answer then find a multiple of the number with the x for example

5x+2=17

17-2=15

Multiples

X1= 5

X2=10

X3= 15

Answer 2

Answer:

I hope this helps :)

Step-by-step explanation:

- 5x + 2 = 17 -- x = 3

- 3x + 5 = 36 -- x = 10.333

- x/3 - 14 = 9 -- x = 7.667 (Might be wrong)

- 73 = 3x - 20 -- x = 31

- 2x - 14 = 7 -- x = 10.5

- 53 = 9x - 1 -- x = 6

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.

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.

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.
