Easy,
write the coordinates out in pairs:
x= hours
y= earnings
(1,10)
(2,20)
(3,30)
(4,40)
(5,50)
Now it makes it much easier to see the increase,
After 1 hour of working she has made $10
After 2 hours of working she has made $20
<span>After 3 hours of working she has made $30
</span>
And so on,
that being said it's easily seen that she is getting paid $10
Thus the unit rate is $10.
Responder:
$ 22
Explicación paso a paso:
Monto principal = $ 20
Tasa de interés = 10% = 10/100 = 0.1
Tiempo = 1 año
Cantidad ganada después de 1 año:
Principal (1 + (tasa de interés * tiempo))
$ 20 (1 + (0,1 * 1))
$ 20 (1 + 0.1)
$ 20 (1,1)
$ 22
Ganará $ 22 después de un año.
Answer:
(2,2) and (3,1)
Step-by-step explanation:
Since we're given the value of y in the second equation, we can replace the y on the left side of the first equation with 4-x, giving us
We can factor the expression on the right to get us
Solving 
and 
gets us the solutions 
, which we can plug into the second equation to get us
So, our solution set is the pair of points (2,2) and (3,1)
Let the original number be

Answer:
2/5
Step-by-step explanation:
5/5 = full job
3/5 = done
full job - done = remaining
5/5 job - 3/5 job
= 2/5 (remaining)
