G = 1.25m + 5
n = 1.50n + 1
g = n
1.25m + 5 = 1.50m + 1 <== ur equation
5 - 1 = 1.50m - 1.25m
4 = 0.25m
4 / 0.25 = m
16 = m <== mary has 16 <==
g = 1.25m + 5....g = 1.25(16) + 5....g = 25 <==Gracie has 25 <==
n = 1.50m + 1...n = 1.50(16) + 1.....n = 25 <==Nancy has 25 <==
Step-by-step explanation:
y is directly proportional to x^2.
This means that y = kx^2, where k is a real constant.
When x = 7, y = 245:
245 = k(7)^2 = 49k. By division, k = 5.
Now we know that y = 5x^2, when x = 9, y = 5(9)^2 = 5 * 81 = 405.
