Answer:

Agency A:  y = 12x

So Agency A pays a rate of $12 per hour

Agency B:  y = 10x + 20

So Agency B pays an initial fee of $20 plus a rate of $10 per hour.

Step-by-step explanation:

Agency A

To create a straight line equation for the data in table, use  [tex]y = mx + b[/tex], where m is the slope and b is the y-intercept.

To find the slope m, take 2 points from the table and use the slope formula.

Let [tex](x_1,y_1)[/tex] = (3, 36)

Let [tex](x_2,y_2)[/tex] = (5, 60)

Slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{60-36}{5-3}=12[/tex]

Now use the point-slope formula to create the final equation:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]\implies y-36=12(x-3)[/tex]

[tex]\implies y=12x[/tex]

Therefore, Agency A pays a rate of $12 per hour.

Agency B

From inspection, the function is a straight line.

Therefore we can use the straight line equation [tex]y = mx + b[/tex],

where m is the slope and b is the y-intercept.

From inspection, we can see that the line crosses the y-axis at (0,20).  Therefore, the y-intercept is 20.

[tex]\implies y=mx+20[/tex]

Taking 2 points on the line and using the slope formula to find the slope m:

Let [tex](x_1,y_1)[/tex] = (0, 20)

Let [tex](x_2,y_2)[/tex] = (3, 50)

Slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{50-20}{3-0}=10[/tex]

Therefore, the final equation is:  [tex]y=10x+20[/tex]

Therefore, Agency B pays an initial fee of $20 plus a rate of $10 per hour.

ANSWER:

y=2x-3

HOPE IT HELPS

Step-by-step explanation:

Add the system of equations each one by one.

I added them all downwards until i found the 4th one to be correct

y = 2x - 3

y = 2x - 3

--------------

2y = 4x - 6

y = 2x - 3.

To find the value of y in each coordinates given above, substitute their respective x values.

1......y = 2(5) - 3

= 10 - 3

= 7.

2......y = 2(8) - 3

= 16 - 3

= 13.

then write the value you substituted in x on the left side of each bracket & the value you got when you substituted them on the right.

(5 , 7) (8 , 13)

The average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.

A slope is also known as the gradient of a line or the average rate of change of a number that helps to know both the direction and the steepness of the line.

The rate of change of any function is the slope of the function, therefore, the slope of the function is written as,

[tex]m = \dfrac{y_2 - y_1}{x_2-x_1}[/tex]

As the value of the y is the function of the x, while the value of x is given, therefore,

[tex]x_2 = 5\\x_1=-2\\\\[/tex]

Now, the value of y,

[tex]y_2 = f(5) = x^2 +2x+3 = (5)^2+2(5)+3 = 38\\y_1 = f(-2) = x^2 +2x+3 = (-2)^2+2(-2)+3 = 3[/tex]

Substituting the value of x and y in the formula of the slope, we can write the slope as,

[tex]m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m = \dfrac{f(x=5) - f(x=-2)}{5-(-2)}\\\\m = \dfrac{38-3}{7}\\\\m= 5[/tex]

Hence, the average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.

Answer:

  d = 15

Step-by-step explanation:

Divide the numbers

[tex]\frac{20}{16} =\frac{d}{12}[/tex]

[tex]\frac{5}{4} =\frac{d}{12}[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]12*\frac{5}{4} =12*\frac{d}{12}[/tex]

Cancel multiplied terms that are in the denominator

[tex]12*\frac{5}{4} =d[/tex]

Multiply the numbers

[tex]15=d[/tex]

Move the variable to the left

[tex]d=15[/tex]

Hence, d= 15.

Freezer A is a better buy in terms of dollars per cubic​ foot.

Step-by-step explanation:

Freezer A: V = 2*2*4 = 16 ft^3

P/V= 400/16 = 25 $/ft^3

Freezer B: V = 2.5*2.5*3 = 18.75 ft^3

P/V= 500/18.75 = 26.6 $/ft^3

--> 25 < 26.6 that mean Freezer A is cheaper per cubic​ foot.

Answer:

(-4, 5)

Step-by-step explanation:

Hi there!
We are given the following system:
x+11y=51

3x+5y=13
And we want to solve it by substitution.
When we solve a system by substitution, we want to solve one of the equations for a variable; the variable should equal an expression containing the other variable. Then, we substitute that expression into the other equation as the variable we solve for, solve for that variable, and then use the value of the solve variable to find the value of the first variable

It's easier to solve for a variable if the leading coefficient in front of that variable is 1, like with x in the first equation (x+11y=51)
To solve this equation for x, we can subtract 11y from both sides.

x+11y=51

  -11y   -11y

_____________
x=51-11y
Now substitute 51-11y as x in 3x+5y=13:

3(51-11y)+5y=13

Multiply

153-33y+5y=13

Combine like terms.

153-28y=13

Subtract 153 from both sides

-28y=-140

Divide both sides by 28

y=5
Now substitute 5 as y in 51-11y to solve for x.

x=51-11y

x=51-11(5)
multiply

x=51-55

Subtract

x=-4

The answer is x=-4, y=5, or as a point, (-4, 5)

Answer:

  155°

Step-by-step explanation:

The obtuse angle of the large (outside) triangle is the supplement of 60°, so is ...

  180° -60° = 120°

The angle x is the sum of the remote interior angles of that large triangle:

  x = 35° +120° = 155°

__

Check

The other acute angle in the smaller (left) right triangle is 90° -35° = 55°. Then the top acute angle in the larger (bottom, right) right triangle is ...

  180° -55° -60° = 65°

The other acute angle in that triangle is 90° -65° = 25°. It is supplementary to angle x. Hence angle x is 180° -25° = 155°, as above. (Note that x is also the sum of 90° and 65°, the remote interior angles of the nearest right triangle to x.)

Answer:21,000

Step-by-step explanation:

350,000 ×6/100 = 350,000×0.00.06 =21,000

The commission earned by the agent is $21,000 which is the 6% of the total selling price.

Percentage is defined as the parts of a number per fraction of 100.  So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Given that,

Price for which the home is sold = $350,000

Percentage as commission earned by real estate agent = 6%

Amount of commission = 6% of $350,000

                                       = 6% × 350,000

                                       = (6/100) × 350,000

                                       = 0.06 × 350,000

                                       = $21,000

Hence the commission earned by the real estate agent is $21,000.
