Answer 1
1/46 = 2/92 = 3/138
Answer 2
x = -7
Answer 3
40
Vertex=(0,0)
directrix is x=2.5
or x-2.5=0
so focus S is (-2.5,0)
let P(x,y)be any point on the parabola.
Let M be the foot of perpendicular from P(x,y) on the directrix.
then SP=PM


Answer:
X = 8.5, Y = 6.5
Step-by-step explanation:
X = # of children's books
Y = # of puzzle books
Amelie wants to buy <u>2 more</u> children's books than puzzle books.
15 - 2 = 13 (Save the 2)
13 / 2 = 6.5
6.5 + 2 = 8.5
So; 8.5 + 6.5 = 15
X = 8.5
Y = 6.5
1/2(x+6)=2x
1/2x + 3 = 2x
x + 6 = 4x
3x = 6
x = 2
5-2x+7x-h
5-2(2)+7(2) = h
h = 5 - 4 + 14
h = 1 + 14
h = 15
55 minus 18 is 37 and then it would be 37,000 and then you just convert it so it is 37% of 100 (the answer is 37%)
