If you know the ratio between a and b, assign the value of a to x and b to y.
You set the slope as b/a. The equation of the line would be y = (b/a)(x)
Any point on the line (besides the origin) would be an equivalent ratio (a:b would be x:y)
A.) If Lucy sells 1 necklace, her sales would equal to $15.99. Then her profit would be:
Profit = $15.99 - $3.38(1) - $5.57(1)
Profit = $7.04
The fraction of the sale price of the necklace in profit is denoted as x.
15.99x = 7.04
x = 704/1559
b.) This is the same as part (a) but in decimal form. Just simply divide 704 by 1559. The answer is 0.44
c.) If Lucy's sales is $223.86 and each necklace costs $15.99, then the number of necklaces sold is $223.86 ÷ $15.99/necklace = 14 necklaces
Her profit for the 14 necklaces sold would be:
$223.86 - $3.38(14) - $5.57(14) = $98.56
Answer:
It is the graph of f(x) shifted 2 units right and 4 units up.
A is correct.
Step-by-step explanation:
We are given two function. One is parent function and another is transform using shifting.
Parent Function:
Now we shift 2 unit right 
Now we shift 4 unit up 
We changed f(x) to g(x) by two transformation
- f(x) shifted 2 unit right then
- f(x) shifted 4 unit up
Thus, we get g(x) by transform of f(x) shifted 2 unit right and shifted 4 unit up.
Multiply 5 for both the numbers in the ratio.
you will get 10 boys and 15 girls which sum to 25 players.
Hope this helps :)
