Answer:

y=3/5x-3

Step-by-step explanation:

First, put the slope in point-slope form: y-y1=x(x-x1)

y+6=3/5(x+5)

Distribute 3/5 to (x+5) and simplify.

y+6=3/5x+3

y=3/5x-3

Anthony grew 64 plants with 32 seed packets.How many seed packets does Anthony need to have a total of 90 plants in his backyard

adelina 88 [10]

Let the total seed packets needed Anthony to have 90 plants be x.

then,
64:32 :: 90:x
2:1 :: 90:x
90 = 2x
x = 45 seed packets.

________________________

64 plants = 32 seed packets.
1 plant = $\frac{32}{64} = \frac{1}{2}$ seed packets.

90 plants = $\frac{1}{2} \times 90 = 45$ seed packets.

Anthony need 45 seed packets to have 90 plants.

What is the distance between p(-300, 200) and Q(500, 400)?

alina1380 [7]

Answer:

200 √17

Step-by-step explanation:

distance between two points (x,y) and (x',y')

D² = (x' - x)² + (y' - y)²

D² = (500 - (-300))² + (400 - 200)² = 640000 + 40000 = 680000

D = √680000 = √4 x 17 x 10000 = 200 √17

Answer:

n^6 is the answer

$n^{6} * n^{\frac{1}{4} } = n^{\frac{25}{4} }$

$\frac{1}{\sqrt[4]{n} } * n^{\frac{25}{4} } = \frac{n^{\frac{25}{4} } }{n^{\frac{1}{4} } } = n^{\frac{25}{4} } - n^{\frac{1}{4} } = n^{6}$
