Answer:

y=-\frac{4}{5}x +4

Step-by-step explanation:

Recall that slope-intercept form is the following form: y=mx+b, where m is the slope and b is the y-intercept.

To get an equation into slope-intercept form, we just need to solve for y.

We begin with the equation 4x+5y=20. With this, we can solve for y to get our answer.

4x+5y=20\\\\5y=-4x+20\\\\y=-\frac{4}{5}x +\frac{20}{5} \\\\y=-\frac{4}{5}x +4

Below is data about the labor market in the state of Northwoods. Wage Quantity Demanded Quantity Supplied $10 80,000 120,000 $9
Mars2501 [29]

Answer:

So the number of people who would be unemployed is 111111.

Step-by-step explanation:

We calculate the total number of people and how much money they will need:

200000\cdot 10\$=2000000\$\\\\200000\cdot 9\$=1800000\$\\\\200000\cdot 8\$=1600000\$\\\\200000\cdot 7\$=1400000\$\\\\200000\cdot 6\$=1200000\$\\

So the total number of people receiving a salary is 1000000.

A total of $ 8000000 is required for their salaries.

If the minimum wage is $ 9, we get:

8000000:9=888888.8\\\\\\1000000-888888.8=111111.2\\

So the number of people who would be unemployed is 111111.

For f(x) to be defined, the expression under the radical must be non-negative.

Therefore, the domain is x ≥ 0, or in interval notation, [0, ∞).

<h3>Calculating total earning </h3>

Cost price is the total amount paid for the jacket while the selling price is the amount they are sold.

Total earning = Selling price  - Cost price

<h3>Find the cost price</h3>

If Dafna makes sport jackets and she is paid d dollars per hour, plus a piece rate of p dollars for each jacket.

Cost price = hd

x is the number of hour

Selling price = jp

total earning = hd - jp

Hence the expression for her total earning willbe t(d) = hd - jp
