3 0

Answer:

  • domain: [0, 1.5]
  • range: [0, 18]

Step-by-step explanation:

Jennie will complete her ride after 1.5 hours, so the function has no utility except for time values between 0 and 1.5 hours.

The domain is the interval [0, 1.5] (hours).

__

The range of the function is the set of possible distances along the trail, so will be values between (and including) 0 and 18 miles.

The range is the interval [0, 18] (miles).

A line has a slope of 2 and passes through the point
Goryan [66]

Answer:

y = 2x + 11

Step-by-step explanation:

The point slope formula for a line is

y - y1 = m(x - x1)

We already have the slope, 2, and we can substitute the point (-4, 3) into (x1, y1):

y - 3 = 2(x + 4)

y - 3 = 2x + 8

y = 2x + 11

consider the following function. f(x)=4x+7. Place the steps for finding f-1(x) in the correct order (photo)
Finger [1]

Step-by-step explanation:

f(x)=4x+7

y = 4x+7

4x = y-7

x = (y-7) /4

the correct answers are:

=> f`¹(x) = (x-7) /4 (a)

=> x - 7 = 4y (e)

=> (x-7) /4 = y (f)

=> x = 4y +7 (g)

Which expression is equivalent to -1/23 (x+24)​
mr_godi [17]

Answer:

-1/23x+-1.043478261

Step-by-step explanation:

Distribute -1/23 to x and 24

-1/23 times x equals -1/23x

-1/23 times 24 equals -1.043478261

So -1/23(x+24) = -1/23x+-1.043478261
