2x + y ≤ 10
<span>y ≤ - 2x + 10 → you can see the line in red </span>
<span>As the sign is ≤, you keep only the part below the red line, included the red line </span>
<span>2x - 4y < 8 </span>
<span>- 4y < - 2x + 8 </span>
<span>y > (- 2x + 8)/- 4 </span>
<span>y > - (1/2)x - 2 → you can see the line in blue </span>
<span>As the sign is >, you keep only the part above the blue line

(totalPrice-discountedPrice)/totalPrice x 100
so that would be:
(380-300)/380 x100 = 21%
<span><u><em>The correct answer is:</em></u>
2.
<u><em>Explanation</em></u><span><u><em>:</em></u>
20 hundreds =20*100=2000;
this is two thousand, so it is made of 2 thousands.</span></span>
For this case we have the following variable:
m = Santana's total marbles
We must write an expression as a function of m to model the problem.
"Santana wants to give one-thenths of all his marbles plus eight to his brother"
The function is:
f (m) = (1/10) m + 8
Answer:
An expression that Santana can use is:
f (m) = (1/10) m + 8
There would be five white flowers and three yellow flowers in every vase. (additional info) Meaning there will be 6 vases.
