Answer:

x = 27

Step-by-step explanation:

3x - 4y = 65

3x = 65 + 4y

<em><u>Find x, when y = 4</u></em>

3x = 65 + 4 (4)

3x = 65 + 16

3x = 81

x = 27             [ \ x = \frac{81}{3}\ ]

A coffee shop charges $2.50 for each cup of coffee and $1.50 for a cupcake. Your mom gives you $10 and ask you to buy 5 cupcakes
Dominik [7]

Answer:

\frac{10-7.50}{2.50}\geqc

1 cup of coffee

Step-by-step explanation:

Let's say c = coffee

5 cupcakes would cost 5*1.50 = 7.50

We can make an inequality :

\frac{10-7.50}{2.50}\geqc

Now we can solve the inequality

10 - 7.50 = 2.50

2.50/2.50 = 1

The maximum cup of coffee you can buy is 1

Hope this helps :)

In Exercise,find the horizontal asymptote of the graph of the function.<br> f(x) = 16x/3+x^2
matrenka [14]

Answer:

Horizontal asymptote of the graph of the function f(x) = 16x/(3+x^2) is y=0

Step-by-step explanation:

I attached the graph of the function. Graphically it can be seen that the horizontal asymptote of the graph of the function is y=0.

When denominator's degree (2) is higher than nominator's degree (1) then the horizontal asymptote is y=0

Please help me to solve this problem
Leto [7]
So you can choose any number from 11 to 19.

I'll choose 11 for now.

Then you write, 11, the number, and then spell it out, eleven.

To show how many tens and ones, you can make a place value chart. You would make two boxes, the first one for tens and the other for ones.

You would put a 1 in the tens place and a 1 in the ones place.

I hope this helps!
