Answer:

Option D: 3x - 9

Step-by-step explanation:

We are told that A banquet table is formed by placing three square-topped tables edge to edge.

This means means that the 4 sides are equal and the length of the entire banquet table is; 3 x side of the table

Now, the table has an area which is x² − 6x + 9.

Thus, one side will be a factor of the quadratic equation.

From quadratic formula, the factor of the equation is; (x - 3)(x - 3)

Thus,one side is (x - 3).

So, length of entire table is;

L = 3(x - 3)

L = 3x - 9

Answer:

the rate charged per hour by the first mechanic is 75 $/hr and the rate charged per hour by the second mechanic is 100 $/hr.

Step-by-step explanation:

A system of equations is a set of two or more equations in various unknowns in which you want to find a common solution.

So, first of all it is convenient to define the system variables:

If the sum of the two rates were $ 175 per hour, then the mathematical expression that represents this situation is: x + y= 175

You know that the first mechanic worked for 20 hours, and the second mechanic worked for 15 hours.  Then the amount of money won by the first and second mechanic respectively is expressed by 20*x and 15*y. Together they charged a total of $3000, then 20*x + 15*y=3000

So, the system of equations to solve is:

[tex]\left \{ {{x+y=175} \atop {20*x+15*y=3000}} \right.[/tex]

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

There are several methods for solving a system of equations. One of them is the substitution method, which consists of solving or isolating one of the unknowns (for example, x) and substituting its expression in the other equation. In this way, you obtain an equation of the first degree with the other unknown. Once solved, you must calculate the value of x by substituting the already known value of y.

In this case, you isolate the variable x from the first expression:

x= 175 - y

Replacing this expression in the second equation:

20*(175 - y)+15*y=3000

and solving you get:

20*175 -20*y +15*y=3000

3500 -20*y +15*y=3000

3500 -5*y=3000

-5*y=3000 -3500

-5*y= -500

y= (-500)÷(-5)

y= 100

So:

x=175 -y

x=175 -100

x=75

Then the rate charged per hour by the first mechanic is 75 $/hr and the rate charged per hour by the second mechanic is 100 $/hr.

Answer:

The rate charged by the first mechanic is $75/h and by the second is $100/h.

Step-by-step explanation:

We have that the two mechanics charged a total of $3000:

[tex] A + B = \$3000 [/tex]    

[tex] A = \$3000 - B [/tex]  (1)

The sum of the rate of the two mechanics was $175 per hour:

[tex] R_{A} + R_{B} = \$175/h [/tex]   (2)          

The rate of the first (A) and second (B) mechanic is:      

[tex] R_{A} = \frac{A}{t_{A}} = \frac{A}{20 h} [/tex]   (3)

[tex] R_{B} = \frac{B}{t_{B}} = \frac{B}{15 h} [/tex]   (4)  

By entering equation (3) and (4) into (2):

[tex] \frac{A}{20 h} + \frac{B}{15 h} = \$175/h [/tex]   (5)            

Now, by entering equation (1) into (5) we have:

[tex] \frac{\$3000 - B}{20 h} + \frac{B}{15 h} = \$175/h [/tex]        

[tex] \frac{-3B + 4B}{60 h} = \$175/h - \$150/h [/tex]

[tex] B = \$25/h*60 h = \$1500 [/tex]        

Now, for the first mechanic we have:

[tex] A = \$3000 - B = \$3000 - \$1500 = \$1500 [/tex]

Finally, from equation (3) and (4) we can find the rate charged per hour by each mechanic:

[tex] R_{A} = \frac{A}{20 h} = \frac{\$1500}{20 h} = \$75/h [/tex]                

[tex] R_{B} = \frac{B}{15 h} = \frac{\$1500}{15 h} = \$100/h [/tex]

Therefore, the rate charged by the first mechanic is $75/h and by the second is $100/h.

I hope it helps you!

Answer:

Ax + By = C

5x + 4y = -20

a is 5, b is 4

Step-by-step explanation:

Find slope:

  m = (y₂ - y₁) / (x₂ - x₁)

      = (0 - (-5)) / (-4 - 0)

     = 5 / -4

  m = -5/4

Use m above and anyone point to find y-intercept, let's use (-4, 0):

  y = mx + b

  0 = -5/4(-4) + b

  0 = 5 + b

  b = -5

Slope intercept form using m and b from above:

  y = mx + b

  y = -5/4x - 5

Standard form Ax + By = C:

  y = -5/4x - 5

  5/4x + y = -5

  5x + 4y = -20

Answer:

50°

Step-by-step explanation:

50 + (3x + 14) + (7x - 4) = 180

50 + 3x + 14 + 7x - 4 = 180

60 + 10x = 180

10x = 180 - 60

10x = 120

x = 120/10

x = 12

So, Angle A is:

(3 * 12) + 14

36 + 14 = 50°

Answer:

a.) [tex]x=12[/tex]

b.) [tex]A=50[/tex]

Step-by-step explanation:

a.) Remember: the sum of all angles in a triangle will always be 180°.

Make an equation in which all given angles add up to 180:

∠1+∠2+∠3=180

[tex](3x+14)+(7x-4)+50=180[/tex]

Solve the equation for the value of x. Remove the parentheses:

[tex]3x+14+7x-4+50=180[/tex]

Combine like terms:

[tex](3x+7x)+(14-4+50)=180\\\\10x+60=180[/tex]

Subtract 60 from both sides:

[tex]10x+60-60=180-60\\\\10x=120[/tex]

Divide both sides by 10:

[tex]\frac{10x}{10}=\frac{120}{10} \\\\x=12[/tex]

The value of x is 12.

b.) Insert the value of x into the given value of ∠A:

[tex]A=3x+14\\\\A=3(12)+14[/tex]

Simplify multiplication:

[tex]A=36+14[/tex]

Add:

[tex]A=50[/tex]

∠A is 50°.

:Done

Check Your Work:

To make sure the given values are true, solve for ∠B:

[tex]B=7(12)-4\\\\B=84-4\\\\B=80[/tex]

Now add all angle values to determine if they add up to 180°:

[tex]50+50+80=180\\\\100+80=180\\\\180=180[/tex]

Since 180 is equal to 180, the values are true.

and h = w/52

Step-by-step explanation:

From the question, we are told that she earns $52 in an hour

So therefore ,

W(h)= 52h

where h is the number of hours she has worked and w is the wages earned for the number of hours worked

The two equations are;

w = 52h

or w/h = 52

Answer:

32 drops of blue food coloring is needed

Step-by-step explanation:

If :

12 drops of yellow food coloring = 8 drops of blue food coloring.

48 drops of yellow food coloring = x

Cross Multiply

12 drops × x = 48 drops × 8 drops

x = 48 drops × 8 drops/12 drops

x = 32 drops of blue food coloring.

If you want to make the same shade of green frosting using 48 drops of yellow food coloring, you would be needing 32 drops of blue food coloring

Answer:

21.5m^2

Step-by-step explanation:

Start by finding the area of the triangle including the rectangle.

The bottom side equals 7m and the other side equals 9m.

To find the area of the triangle, you multiply the base by the height, then divide by 2: (bh)÷2

(7*9)÷2=63/2m^2 or 31.5m^2

Now you can find the area of just the shaded region. To do this, you will want to find the area of the rectangle then subtract it from the area of the triangle.

To find the area of the rectangle, multiply the length by width.

2*5=10m^2

Now you can subtract the areas.

31.5-10=21.5m^2

They are the same because they have the same slope but are different because they have different y intercepts.

Step-by-step explanation:

The slope of both lines is the same. Then the line is parallel to each other.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equations are given below.

y = 2x

y = 2x - 7

The slope of both lines is the same. Then the line is parallel to each other.

But the first line is passing through the origin and the second line is passing through (0, -7).

The graph is given below.
