Len [333]2 years ago

Answer:

The first one is a function because, for each x-value (domain value) there is exactly one y-value (range value).

The second one is not a function because, not each x-value (domain value) has exactly one y-value (range value). The domain value of 5 has two range values of 13 and 9.

-2.1b +5.3= b -- 3.1b + 5.3<br><br> does is have one solution or infinitely many solutions ? Why ?
pychu [463]

Answer: infinitely many solutions.

Step-by-step explanation:

Ok, our equation is:

-2.1*b + 5.3 = b - 3.1*b + 5.3

now, simplifyng the right side, we have:

b - 3.1*b + 5.3 = (1 - 3.1)*b + 5.3 = -2.1*b + 5.3

Then our initial expression is:

-2.1*b + 5.3 = -2.1*b + 5.3

So in both sides of the equality we have the exact same thing, so this is a trivial equality.

This means that the equality will remain true for any value of b, which means that we have infinitely many solutions.

In​ 2000, 54% of the residents in a large city regularly used newspapers for getting news and this has decreased at an average r
Anika [276]
X=number of years after 2000.
y=percentage of residents (still) reads newspapers for information
initial value (= y-intercept) = percentage in 2000 = 54%
slope = increase each year = -1.7% (because it is a decrease)
the slope intercept form of the equation is therefore:
y=slope(x)+initial value, or
y=-1.7x+54   (in %)

Every year Ethan earns 38,428. Each year he spends 21,728 on expenses. How much money should he have left over?
PolarNik [594]

Answer:

16,700

Step-by-step explanation:

Given that,

Earning of Ethan = 38,428

Ethan spends 21,728 on expenses.

We need to find the amount of money he has left over. It can be calculated as follows :

Left money = Earning - Spent

= 38,428 - 21,728

= 16,700

So, he has left over 16,700.
