What is the exact value of cos(-60°)?​

Answer:

[tex]2c-4[/tex]

Step-by-step explanation:

So we have the expression:

[tex]8c-1-3(2c+1)[/tex]

First, distribute the -3:

[tex]=8c-1-3(2c)-3(1)[/tex]

Distribute:

[tex]=8c-1-6c-3[/tex]

Combine like terms:

[tex]=(8c-6c)+(-1-3)[/tex]

Simplify:

[tex]=2c-4[/tex]

Answer:

2c-4

After you combine the terms the answer is : 2c-4

Answer:

P(t) = 10t - 400

Step-by-step explanation:

Selling price of each ticket = $10

Cost of setting up the dance= $400

Profit = Revenue - cost

Revenue = price × quantity

Revenue that will maximize profit = 10t

where t= quantity of tickets that maximises profits

Cost = $400

Profit(t) = Revenue - cost

P(t)= 10t - 400

We want to find the equation that represents the school's profit. We will get:

P(x) = $10*x - $400

We know that the tickets to the school dance are sold for $10 each, then the revenue, if they sell x tickets, is just:

r(x) = $10*x

And we know that they spent a total of $400.

Remember that profit is defined as the difference between revenue and costs, so the profit equation is just:

P(x) = $10*x - $400

Answer:

3/5 c + 70 = 1650.

Step-by-step explanation:

If c is the number of calories in the cheeseburger, we can see that the entire number of calories for the meal is 3/5 c + 70 = 1650.

If we want to isolate c, we can subtract both sides by 70.

3/5 c = 1580

Answer:

C = [5(1650 - 70)]/3

Step-by-step explanation:

We write the equation: 1650 = 70 + 3C/5

Subtract 70 from both sides: 1650 - 70 = 3C/5

Multiply 5 on both sides: 5(1650 - 70) = 3C

Divide 3 on both sides : C = [5(1650 - 70)]/3

Answer:

B. Jenny paid $322 for 23 T-shirts, which is a rate of $14 per T-shirt.

Step-by-step explanation:

To find the rate per shirt, divide the cost by the number of shirts:

322/14

= 14

So, she paid $322 at a rate of $14 per shirt.

Therefore, B is correct.

Answer:

x = -4

Step-by-step explanation:

Step 1: Write out given

f(x) = -3

f(x) = 2x + 5

Step 2: Substitute f(x)

-3 = 2x + 5

Step 3: Solve for x

-3 - 5 = 2x + 5 - 5

-8 = 2x

-8/2 = 2x/2

-4 = x

Answer:

Step-by-step explanation:

f(x)=2x+5

To find f(x)=−3 equate f(x) to - 3 and evaluate

That's

2x + 5 = - 3

Subtract 5 from both sides

That's

2x + 5 - 5 = - 3 - 5

2x = - 8

Divide both sides by 2

[tex] \frac{2x}{2} = - \frac{8}{2} [/tex]

Answer:

Answer to (4+5): (0,0)

Answer to 6: 0

Step-by-step explanation:

(4+5 Explanation):

We can start to imagine the graph of [tex]y=|x|[/tex] in our head.

If we have a positive value of x, then y will be equal to x.

If we have a negative value of x, then y will be the opposite of x (since the absolute value of a negative is a positive).

This means that the graph will look a bit like this, changing at the point (0,0).

\/, it would look like a downward facing arrow. This means the vertex is at (0,0).

Answer:

C

Step-by-step explanation:

So we have the following sequence:

-7, -3, 1, 5...

As given, the (direct) formula for any arithmetic sequence is:

[tex]a_n=a_1+d(n-1)[/tex]

Where aₙ is the value of the nth term, a₁ is the value of the first term, and d is the common difference.

From the sequence, we can see that the initial/first term is -7. Thus, a₁ is -7.

And we can see that each subsequent number if 4 greater than the previous one. Thus, the common difference is +4.

Therefore, plugging these into our equation, we have:

[tex]a_n=-7+4(n-1)[/tex]

The answer is C.

Answer:

The average cost this year = $33,093.75

Step-by-step explanation:

The computation of the average cost this year is shown below:

Given that

The average cost for the last year = $31,250

Increased percentage = 5.9%

Based on the above information, the average cost this year is

= The average cost for the last year × (1 + Increased percentage)

= $31,250 × (1 + 0.059)

= $31,250 × 1.059

= $33,093.75

Answer:

$62,000

Step-by-step explanation:

There are 20 people.

You have to add $5000 and $1200, which equals $6,200.

You have to multiply that by 10 to get the answer.

Start by graphing each line.

• Because the first inequality is smaller than, it will have a dotted (- - -) line.

• Because the second inequality is smaller than or equal to, it will have a solid line (---).

Then, plug in points to see where your shading will go. If the statement is true (x = x), you will shade that area along the line.

[tex]y < 3x + 2[/tex]

[tex](0) < 3(0) + 2[/tex]

[tex]0 < 2[/tex]

0 is less than 2.

Do the same step for the other equation. Your solution to the problem is any point that lies between the shading from both inequalities (where the blue and red meet).
