What is the slope of the line that contains the points (8, 3) and (8, 7)?

1 answer:

8 0

The slope can be obtained by (y2 - y1) / (x2 - x1). In this example, using the two points, we have
(7 - 3) / (8 - 8 ) = 4 / 0.
Division by 0 is undefined.
So, the answer is (d) The slope is undefined.

Your school buys 30 graphing calculators for 1822.50. Write and solve a proportion that gives the cost c of buying 120 calculato

natali 33 [55]

Answer:

7290

Step-by-step explanation:

Using proportion then

$\frac{1822.5}{30}$ = $\frac{c}{120}$ ( cross- multiply )

30c = 18700 ( divide both sides by 30 )

c = 7290

The cost of 120 calculators is 7290

Which graph is an example of a function whose parent function is y=sqrt x?

hoa [83]

See in the explanation

<h2>Explanation:</h2>

Hello! Recall that you have to post complete questions in order to get excellent and correct answers. Since you have missing graphs, I can't say what is the correct option. However, I'll try to help you about the concept of parent functions.

A parent function is the most basic function that shares the same characteristics with other complicated functions. One of the parent function in mathematics is the Square Root Function written as:

$y=f(x)=\sqrt{x}$

This parent function is shown in the First Figure below. As you can see:

The domain is the set of all real numbers greater (or equal) than zero
The range is the set of all real numbers greater (or equal) than zero

An example of a function whose parent function is $f(x)=\sqrt{x}$ is the same function translated three units to the left. In a mathematical language:

$g(x)=\sqrt{x+3}$

This graph is shown in the second figure. As you can see, these two graph share the same characteristics. The only difference is a translation performed on the second one. For the second graph, we have:
