What is the average rate of change of f(x), represented by the table of values, over the interval [-2, 3]?

Mathematics

Pavel [41]3 years ago
4 0

Answer:

  0.5

Step-by-step explanation:

The average rate of change (m) on the interval [a, b] is ...

  m = (f(b) -f(a))/(b -a)

On the interval [-2, 3], the average rate of change is ...

  m = (5 -2.5)/(3 -(-2)) = 2.5/5 = 0.5

2t-7-5t=11 what is the answer
Verizon [17]
<span>2t-7-5t=11

Start by combing like terms:

2-5t=-3t  

Now we have: 

-3t-7=11  

Add 7 to both sides

-3t=18

To isolate t we divide both sides by -3 

Final answer: 
t=-6 </span>

Eight times a number plus five another number is -13. The sum of the two numbers is 1. What are the numbers?
Pani-rosa [81]
Eight *(a number) plus 5*(another number) is -13.

translates to:

8(x) + 5(y) = -13

The sum of (the number) and (the other number) is 1.

translates to:

(x) + (y) = 1


We have a system of two equations involving two unknowns: x and y.

\rm 8x+5y=-13\\&#10;~~x+~~y=~~~~1

We can easily solve the system using Substitution or Elimination. Let's use Elimination this time.

We'll multiply the second equation by -8 so that the x's match up.

\rm ~~~8x+5y=-13\\ -8x-8y=-8

When we add the equations together, the x's will fall out of the equation, summing to zero. The 5y and -8y will sum to -3y and the right hand side will sum to -21.

\rm -3y=-21

Divide by -3,

\rm y=7

Plug back into one of your original equations to find the value of x,

\rm x+y=1\\&#10;x+7=1

Subtract 7,

\rm x=-6

The original square has the area (8 in)^2 = 64 in^2.

If we mult. this area by 36, we get the area of a larger square 2304 in^2.

The new side length is sqrt(2304 in^2), or 48.  In other words, the original square has side length 8 in, but the 'new' square has side length 48 in.
