Step-by-step explanation:
y=3x+1, y= -3x+7
y=1,X=1
X+y=10,2x+2y=20
X=5, y=5
Answer:
D
Step-by-step explanation:
Direct Variation takes the form
Inverse Variation takes the form
- Where A and B are the 2 variables associated and k is the proportionality constant.
<em>Since </em><em>number of dolls [N] </em><em>varies </em><em>directly </em><em>with </em><em>advertising budget [A],</em><em> in our equation, </em><em>A should go in the numerator</em><em> and since </em><em>number of dolls [N] </em><em>varies </em><em>inversely</em><em> with </em><em>price of dolls [P]</em><em>, </em><em>P should go in the denominator.</em>
Thus we can write our equation as:
Solving this equation for k given the information "The company sold 5200 dolls when $26,000 was spent on advertising and the price of a doll was set at $30":
Rounding to
Now, given that we want to find the number of dolls [N] when and , we have:
dolls
Answer choice D is correct.
1. Area=30
4.Area=3.68
2.Area=75
S + g = 350; /*(-3) => -3s - 3g = -1050;
3s + 5g = 1450;
=> 2g = 400 => g = 200 ( general admission tickets);
=> s = 350 - 200 => s = 150 ( student tickets);
