Answer:

y = - 2

Step-by-step explanation:

y =  \frac{2}{3} x \\  \\ plug \: x =  - 3 \\  \\ y =  \frac{2}{ \cancel3}  \times (    \cancel{ - 3})  \:  \:   \red{ \bold{- 1}}\\  \\ y = 2( - 1) \\  \\ y =  - 2

Q1 of company B = 2
Q3 of company B = 5.5
Interquatile range = (5.5 - 2)/2 = 3.5/2 = 1.75

Feather blew out of a bird nest 10 feet in the air. It drifted to the ground at a constant rate of 2 feet per second.
PIT_PIT [208]

The equation that  shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.

Let x represent the time in seconds for the bird feather to reach 10 feet.

Hence:

y = -2x + 10

The equation that  shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10

12. The circumference of a quarter is about 76 mm. What is
77julia77 [94]

Answer: A= 460 mm2

Step-by-step explanation:

Hi, since the circumference formula is :

C = 2 π r

Where r is the radius, we can solve the formula for the radius replacing with the value given:

76 =2 π r

76 / (2 π) = r

r = 12.1 mm

Now , we have to apply the formula for the area of a circle.

A = π r^2

A = π (12.1)^2

A= 459.96 mm2= 460 mm2 (rounded to the nearest tenth, since .9 is higher than .5)

Feel free to ask for more if needed or if you did not understand something.
