Pls help me i just need help

Mathematics
1 answer:
Ray Of Light [21]2 years ago
4 0

Step-by-step explanation:

the total cost is, of course, first the cost to buy the copier, and then the running costs per copy made.

it is really that easy.

the equations just put this into mathematical form :

A

y = 0.02×x + 800

B

y = 0.06×x + 600

please notice, we put $600 or $800 in as constant term, because these costs are the starting costs that we have, even if we never make a single copy (x = 0).

and then the total cost goes up with every copy we make.

I cannot draw here.

so, to find the number of copies where both copier systems would cost the same, means we have to say both equating deliver the same result :

0.02×x + 800 = 0.06×x + 600

200 = 0.04×x

x = 200 / 0.04 = 5000

when making 5000 copies both costs are the same.

Write a function rule for “The output is 5 less than four times the input.” Use x for the independent variable and y for the dep
Ludmilka [50]

Answer:

y(x) = 4x - 5

Step-by-step explanation:

A dependent variable depends on other factors that are measured . The value of a dependent variable depends on the independent variable. The independent variable stands alone and it does change by the other variable you are trying to measure. Independent variable are usually denoted as x.

The function can be represented below.

y(x) = 4x - 5

x = independent variable

y = dependent variable

y depends on the value of x

can I please get a labeled homework help im confused and last thing please don't make to much long equation because I cant do so
zepelin [54]

Answer:

your answer is x >18

Step-by-step explanation:

Jahsiah's mistake was he added 9 to both sides of the equation. He should have subtracted 9 from both sides of the equation.

Here's the solution

-2x+9<-27

-9 -9

-2x/-2x<-36/-2x

when u divide by negative in inequalities, u change the sign. So ur correct answer is x>18

hope this helped.
