If f(x) = one-half left-bracket x right-bracket, what is f(7.6)? 3 3.5 3.8 4
Anton [14]

This is a method of substituting values into a given function. The value of the function f x is 7.6 is 3.8

<h3>Functions and values</h3>

Given the following function expressed as:

f(x) = 1/2(x)

We are to determine the value of f(7.6). Substitute x = 7.6 into the function as shown:

f(7.6) = 1/2(7.6)

f(7.6) = 7.6/2

f(7.6) = 3.8

Hence the value of the function f x is 7.6 is 3.8

1. Which graph represents a proportional relationship ​
stealth61 [152]

Answer:

A graph that has an originality.(0,0) (this is the main thing. More below!!)

Step-by-step explanation:

  • it might be positive or negative. it should also be linear.
  • it also should not have a y-intercept.( the point where the line crosses the y axis)
  • so for example a graph with an equation of y =3x or y=-3x is proportional. It has an originality since there is no y-intercept which is b in an equation. It also has a steady rate or slope of 3 which makes it linear.

Sierra drives for h hours at a rate of 2x miles per hour. Which expression shows the distance that she drives after h hours
Eva8 [605]

Answer:

Distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh

Explanation:

Distance traveled by a body = Velocity of the body * Time taken by the body

Here velocity of Sierra =  2x miles per hour

Time taken by Sierra = h hours.

Distance traveled by Sierra = 2x * h = 2xh

So distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh
