Answer:

y = - 1/3x + 10

Step-by-step explanation:

Step 1:

y = mx + b Slope Intercept Form

Step 2:

y = - 1/3x + b Input Slope

Step 3:

9 = - 1/3 ( 3 ) + b Input x and y

Step 4:

9 = - 1 + b Multiply

Step 5:

10 = b

Answer:

y = - 1/3x + 10

Hope This Helps :)

Amanda's school is due west of her house and due south of her friend Shereen's house. The distance between the school and Sheree

Blizzard [7]

The Amanda's house is 6.7 km far from her school.

Step-by-step explanation:

From the given information,

The Amanda's school is due west of her house forms the base.
The school is due south of the Shereen's house forms the height.
The straight-line distance between Amanda's house and Shereen's house forms the hypotenuse.

Therefore, It can be determined that it forms the right angle triangle.

It is given that,

The distance between the school and Shereen's house is 2 kilometers.

That is, the height of the triangle = 2 km

The straight-line distance between Amanda's house and Shereen's house is 7 kilometers.

That is, the hypotenuse of the triangle = 7 km

Now, the distance between the Amanda's house and her school is the base of the triangle.

To find the base :

Base = $\sqrt{(hypotenuse)^{2}-(height)^{2} }$

⇒ $\sqrt{(7)^{2} -(2)^{2} }$

⇒ $\sqrt{49-4}$

⇒ $\sqrt{45}$

⇒ 6.7 km

Therefore, the Amanda's house is 6.7 km far from her school.

kari74 [83]

Answer:

2560000

Step-by-step explanation:

2.56 x 10⁶

Since the exponent is positive 6, you can "move" the decimal place 6 times to the right.

Put in a bunch of 0's so you don't get lost:

2.56000000000000

Move 6 over -->>

2560000
