Just convert to standard form using Ax + By = C = -(A/B) where A = -9 and B = 5.
m = -9/1 which translates to -9.
Our slope is -9.

Answer:

Slope= -9

Step-by-step explanation:

Remember that functions in the form of the slope are represented like this:

Y=mx+c

The function that is given to us just moves C of place, and the m is the number that is located right aside of the variable x, so the slope is -9, this is how much would the graph will grow or decrease with the increase on the value of the variable x.

If an object is dropped from a height of 96ft, the function h(t) = -62 + 96 gives the height of the object after t seconds. When
Shalnov [3]

Answer:

Step-by-step explanation:Since we want to know how much time elapsed since the object was launched until it ht the ground. At the ground, the height is 0.

 

Therefore the equation  h(t) = 80t – 16t2 becomes 0= 80t – 16t2

 

Solving the equation for t gives  80t =16t2 or 16t=80 or t=5sec

 

The object hits the ground 5 seconds after it is launched.

The required equation of the line is y = -1/2x

<h3>Equation of a line</h3>

The standard equation of a line is expressed as y = mx + b

  • where:
  • m is the slope
  • b is the y intercept

Given the coordinate points (0,0) and (4, -2)

Slope  = -2/4 = -1/2

The intercept is 0 since the line pass through the origin

Hence the required equation of the line is y = -1/2x

What is the median of the following salary list $32,019, $21,971, $27,512, $43,702, $38,860, $25,997
mylen [45]

Answer:

$29765.50

Step-by-step explanation:

Median is the middlemost value (or the average of the 2 middlemost value if there are even number of values) in an ascending order.

First, arrange the salary list in an ascending order.

$21,971 , $25,997 , $27,512 , $32,019 , $38,860 , $43,702

As we can see here, there are even number of values (6), so the median will be the average of the 2 middlemost value, which will be:

Median = \frac{27512 + 32019}{2}

= \frac{59531}{2}

= $29765.50

9 stores is 3% of how many stores?
hichkok12 [17]
Hello there! We can solve this question by writing and solving a proportion. Set it up like this:

9/x = 3/100.

This is because 9 is 3% of x number of stores and percents are parts of 100. Setting it up like this will help us get the correct answer. Cross multiply the values . 9 * 100 is 900 and 3 * x = 3x. You get 900 = 3x. Now, divide each side by 3 to isolate the x. 3x/3 cancels out the x. 900/3 is 300. There. x = 300. 9 stores is 3% of 300 stores.
