Level 3: A plumber charges $50 for a service call plus $75 per hour of service. What will be the total cost for 8 hours of work? *
$650
$600
$475
$400

Answer: the answer is A

Step-by-step explanation:

Answer: If by m you mean meters and not a variable, then you get 4 for the length of the sides. If you mean m as a variable, then the answer is 2m

Step-by-step explanation: First simplify the equation by squaring 4. This gives you the area, which is 16. Then take the square root of 16 to get the area, which is 4. If m is a variable in the equation then you must take the square root of  (4m^2) and the answer you get for the side length you get is 2m

Answer:

5878600 different playlists.

Step-by-step explanation:

Since we require 14 songs for the playlist and there are 7 hip-hop, 5 jazz, 7 pop, and 8 blues songs, and DJ Mykel wants to play no more than 3 hip-hop songs, the number of ways in which he can combine the 7 hip-hop songs to play no more than 3 is ⁷C₃ = 7!/4!3!.

Now, since we have 3 songs already selected, we are left with 14 - 3 = 11 songs to select.

Since we have selected the 3 hip-hop songs, we are left with 5 jazz, 7 pop, and 8 blues songs which sum to a total of 20 songs.

So, we have 20 songs to select in 11 ways which is ²⁰C₁₁ = 20!/(20 - 11)!11! = 20!/9!11!

So, the number of different playlists that can be formed is thus

⁷C₃ × ²⁰C₁₁ =  7!/4!3!.× 20!/9!11!

= 35 ×  167960

= 5878600 different playlists.

Answer:

y=x+2

Step-by-step explanation:

we know the slopes have to be equal because the lines are parallel, so the slope is 1, or written as x. plug the point given, (-6,-4), and the slope, 1, into the y=mx+b equation to find the y-intercept. then solve. then put the slope and y-intercept together for the equation of line h.

y=mx+b, m=1, x=-6, y=-4

-4=(1)(-6)+b

-4=-6+b

2=b

y=x+2

Answer:

interest: $60

Payment: $360

Step-by-step explanation:

I = Prt

Interest for four years = 300 * 0.05 * 4 = 60

P = P₁ + I = 300 + 60 = 360

Answer:

Undetermined x=x

Step-by-step explanation:

First, you need to simplify each side by combining like terms:

(5x - 7x)(+3-4) = (2x - 4x) +1

-2x - 1 = -2x + 1 is your simplified expression.

After adding 1 to both sides, you're left with: -2x = -2x

You can divide both sides by -2, you'd get: x = x

Therefore, it's undetermined. Meaning, there are no possible solutions or there's infinite solutions. In this case, there's infinite solutions.

Answer:

[tex]y = 2x - 5[/tex]

Step-by-step explanation:

[tex]y = mx + b[/tex]

We need to leave y-term as the subject of equation.

[tex] - 4y = 20 - 8x[/tex]

Move 8x to subtract.

[tex]y = \frac{20 - 8x}{ - 4} [/tex]

Pull the negative out of 4.

[tex]y = - \frac{20 + 8x}{4} [/tex]

Simplify

[tex]y = - \frac{20}{4} + \frac{8x}{4} \\ y = - 5 + 2x[/tex]

Swap x-term and constant.

[tex]y = 2x - 5[/tex]

Answer: No real solutions.

Step-by-step explanation: −x2=8x+20

Step 1: Subtract8x+20  from both sides.

−x2−(8x+20)=8x+20−(8x+20)

−x2−8x−20=0

For this equation: a=-1, b=-8, c=-20

−1x2+−8x+−20=0

Step 2: Use quadratic formula with a=-1, b=-8, c=-20

Given:

The inequality is [tex]y<-2x-4[/tex].

To find:

The graph of the given inequality.

Solution:

The inequality is

[tex]y<-2x-4[/tex]

The related equation is

[tex]y=-2x-4[/tex]

For x=0,

[tex]y=-2(0)-4[/tex]

[tex]y=0-4[/tex]

[tex]y=-4[/tex]

For y=0,

[tex]0=-2x-4[/tex]

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

[tex]\dfrac{4}{-2}=x[/tex]

[tex]-2=x[/tex]

So, the related line passes through two points (0,-4) and (-2,0).

Sign of inequality is <, so the related line is a dotted line and shaded region is below the related line.

Therefore, the correct option is B.

Answer: p = 1

Step-by-step explanation:

2/5 + p = 4/5 + 3/5p

-2/5        -2/5

      p = 2/5 + 3/5p

-3/5p            -3/5p

2/5p = 2/5

Divide both sides by 2/5

p = 1

The equation produces the values in the table is y = x/4

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

For example, 2x – 5 = 13.

Given is table (attached) we need to determine an equation that produces the values in the table,

So, seeing the value it is much that the value of x are the 4 times of the values of y,

So, we can write,

4y = x

or, y = x/4

Hence, the equation produces the values in the table is y = x/4

~I hope I helped you :)~

I hate math

First thing's first, PEMDAS. There's nothing to solve in the parenthesis, and there are no exponents, so use multiplication next. 6 • (x-2) and -8 • (x-3)

Your equation after should be

5x + 6x - 12 - 8x + 24

Next would be addition, don't forget it's always left to right.

11x - 12 - 8x + 24

Subtract twelve from the total (or in this case just from 24, and then add the remaining values (that are possible).

11x - 8x + 12

Next, subtract the two remaining x values.

3x + 12

And there you have it. Easy peasy.

If the case is trying to find x, just solve it like this.

3x = -12

x = 4
