For this case we have to:

x: It is the variable that represents the quantity of paint bottles

y: It is the variable that represents the number of boxes of colored pencils

So, we have:

2x + 3.50y

If you can not spend more than $ 42 then we have:

2x + 3.50y\leq42

Then you can buy 10 boxes of colored pencils and 3 of paint bottles at a cost of $ 41

2 (3) +3.50 (10)\\6 + 35 = 41

You can buy 5 boxes of colored pencils and 12 of paint bottles at a cost of $

2 (12) +3.50 (5)\\24 + 17.5 = 41.5

You can buy 7 boxes of colored pencils and 8 of paint bottles at a cost of $

2 (8) +3.50 (7)\\16 + 24.5 = 40.5

Answer:

2x + 3.50y\leq42

What are the zeros of the function f(x) = x^2 + 5x + 5 written in simplest radical form?
Klio2033 [76]

Answer:

2x = -5 +/- root 5 (opt 3)

Step-by-step explanation:

0 = 4f(x)

 = 4(x^2 + 5x + 5)

 = 4x^2 + 20x + 20

 = (2x)^2 + 2*2x+5 + 25 - 5

 = (2x + 5)^2 - (root 5)^2

 = ((2x+5) - 5) ((2x + 5) + 5)

 = (2x + 5 - 5) (2x + 5 - 5)

Therefore, 2x = -5 +/- root 5

Hope u understand.

Dennis_Churaev [7]

we know that

Celia bought a bag of 12 goldfish for \$3

so

by proportion

Find the cost of 1 goldfish

\frac{3}{12} \frac{\$}{goldfish} =\frac{x}{1} \frac{\$}{goldfish} \\ \\x=3/12 \\ \\x=\$0.25

therefore

<u>the answer is</u>

The cost of one goldfish is \$0.25

Which equation represents h(x)?
Lelechka [254]

Answer: The second choice: h(x) = (f(x))(g(x))

Step-by-step explanation:

f(x) = -15

g(x) = 15

h(x) = -225

-15 * 15 = -225

Therefore, h(x) is the distribution of f(x) and g(x).
