Answer:

f(x) has y-intercept at (0,-1). g(x) is unknown since inputs (x) are missing int he table.

Step-by-step explanation:

f(x) has the equation y = 4x - 1 which is y = mx + b. This form has the y-intercept directly in the equation as b. So b = -1.

g(x) has no input values in the table. The y -intercept is located where x = 0. Since there are no input values, the y-intercept can not be found without more information.

You give up a full time salary of $45,000 a year to go to school for two years that cost $30,000, to recover your investment in

Tpy6a [65]

The minimum salary you need earn per year is $ 69, 000

Solution:

You give up a full time salary of $45,000 to go to school for two years

Find the salary for two years

Salary for two years = 45000 + 45000 = 90000

Thus salary for two years is $ 90,000

Cost for school is $ 30,000

Total cost: salary for two years + cost for school

30, 000 + 90, 000 = 120000

So you need to recover $ 120000 in total

To recover your investment in 5 years or less what is the minimum salary you need to earn

Therefore,

$\rightarrow \frac{120000}{5} = 24000$

So each year you would have to earn 45,000 + 24,000 = 69, 000

Thus the minimum salary you need earn per year is $ 69, 000

In the first 4 hours it is open, the deli sells 23 hams. The deli expects to sell h more hams before the end of the day. Write t

Anika [276]

Assuming they're expecting to sell at the same rate:

first we divide the number of hams sold by the time it took to sell them

23/4=5.75

this is is the rate per hour at which the hams are being sold

y=23+h
h=5.75*x

in these two equations, y=the total number of hams sold and x= the number of hours the store is open after the first 4 hours
