Hello :
<span>the parabola's equation is : f(x) = a(x+3)²-1
</span><span>the coefficient of the squared expression in the parabola's equation is : a
but ; f(4) = 0
0 = a(4+3)²-1
49a-1=0.....a=1/49
f(x) = 1/49(x-3)²-2</span>
Answer:
(x, y) = (8, 2)
Step-by-step explanation:
substitute x = 4y into the other equation
2(4y) + 4y = 24
8y + 4y = 24
12y = 24 ( divide both sides by 12 )
y = 2
substitute y = 2 into x = 4y
x = 4 × 2 = 8
solution is (8, 2 )

The amount more of rain that fell in those three days than normally falls in July and August combined was 31.19 cm.
<h3>How much more rain fell in those three days?</h3>
The amount of rain in those three days was 41.2 cm.
The combined normal rain July and August is:
= 6.36 + 3.65
= 10.01 cm
The difference is therefore:
= 41.2 - 10.01
= 31.19 cm
