12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric
she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds
each dog bed sells for 17.50.....5 * 17.50 = 87.50
87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==
Answer:
The constant of proportionality is 12.
Step-by-step explanation:
Let's take a look at the formula give to us:
48=4k
First, we have to isolate the variable, K, by dividing 4 on both sides.
48/4=4/4 k
48/4=12
12=k
We can check the answer by plugging it back into the equation:
12*4=48
48=48
Hence, the variable k equals 12.

Answer:
(h, k) = (9, -8)
Step-by-step explanation:
The function g(x) is "vertex form" for a quadratic whose vertex is (h, k). We are told the vertex is (9, -8), so we have ...
(h, k) = (9, -8) . . . . the values of h and k
Answer:
x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.
Step-by-step explanation:
f(x) = −x² + 50x − 264
−x² + 50x − 264 = 0
-x² + 44x + 6x - 264 = 0
-x(x - 44) + 6(x - 44) = 0
(x - 44)(-x + 6) = 0
x = 6, 44
