Answer:

They would be 44.6 miles apart

Step-by-step explanation:

Here, we want to calculate how far they will be in 1 hour

Mathematically;

Distance = speed * time

In 1 hour, Kiran would have traveled a distance of 3 * 1 = 3 miles

While Clare would have traveled a distance of 3.4 * 1 = 3.4 miles

Now, we want to calculate how far apart they would be

On the 24 miles trail, Kiran would be at a distance of 21 miles to the other end

On the 24 miles Claire would be at a distance of 20.6 miles

So how far apart they would be is

24 miles + 20.6 miles = 44.6 miles

What is the rang for the equation y=2x-3​
a_sh-v [17]

Answer:

The range for the equation is all real numbers.

Step-by-step explanation:

The range of an equation is the set of y-values that you can get by plugging in all possible x-values.

Another way to put it is, when you graph the equation, whatever y-values the line produces, is its range.

Graphing y=2x-3, you can see it is a graph with a positive slope that extends from negative infinity y-value to positive infinity x-value.

The difference of two numbers if four and their product is 60
cricket20 [7]

Answer:

The two numbers are 10 and 6.

Step-by-step explanation:

Let's begin by calling these two numbers x and y, and setting up a system of equations.

x-y=4

x*y=60

Now, you can rearrange the first equation to find the value of x expressed through y.

x=y+4

Now, you can substitute this into the second equation.

(y+4)*y=60

y^2+4y=60

y^2+4y-60=0

(y-6)(y+10)=0

y=6

x=6+4=10

Hope this helps!

Answer:

f(-121) = -5

f(31) = 3

General Formulas and Concepts:

  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = ∛(x - 4)

f(-121) is x = -121

f(31) is x = 31

<u>Step 2: Evaluate</u>

f(-121)

  1. Substitute in <em>x</em>:                    f(-121) = ∛(-121 - 4)
  2. [Radical] Subtract:               f(-121) = ∛(-125)
  3. [Radical] Evaluate:              f(-121) = -5

f(31)

  1. Substitute in <em>x</em>:                    f(31) = ∛(31 - 4)
  2. [Radical] Subtract:               f(31) = ∛27
  3. [Radical] Evaluate:              f(31) = 3
