Fantom [35]

Answer:

A. the equality means that the two equations should be equal in a certain x value. Solving the x for these equation gives you the x point where the 2 equations intersect.

B. The x value where the funcionts intersect is x = 1

Step-by-step explanation:

You can solve the x value using natural logarithms.

If you make a table for the two functions you will also see the result:

Value             y = 8^x            y = 2^(x+2)

 -3                    0,00195          0,5

 -2                    0,0156             1

 -1                     0,125               2

  0                     1                      4

  1                      8                     8

  2                      64                  16

  3                      512                  32

What is the number of times a base is multiplied by its self indicated by an exponent
lozanna [386]

The question is worded a bit strangely (in my opinion anyway), but I think your teacher wants you to describe how exponents work.

Let's say we had the expression 5^3

The base is 5 as its the bottom most value (think of something like the base of a tree or building). The exponent is 3.

The exponent of 3 tells the reader to multiply the base 5 by itself 3 times like so

5^3 = 5*5*5 = 125

With larger exponents, it becomes more tedious to write out all the repeated multiplications, which is why many calculators have an exponent button to save time.

How do you find the point slope form? (given 2 points)
belka [17]

Point-slope form is written as : y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point.

The slope (m) is found by the change in Y over the change in X

Slope = (y2 - y1) / (x2 - x1)

You can use either given point for x1 and y1 so you would calculate the slope and replace m with the slope, then replace x1 and y1 in the equation with their value.

It costs Sally 20 cents to make a cup of lemonade, and she sells each cup for 50 cents. She is using the following identity to c
mote1985 [20]

She would make 3.00 dollars


50(10) - 20(10) = (10)(50 - 20)

500 - 200 = (10 * 30)

300 = 300


(10)(50 - 20) = 30(10)

(10 * 30) = 300

300 = 300
