$\bf \begin{array}{llccll}
y=&1x^2&-6x&+9\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad discriminant\implies b^2-4ac$

so... what does that give you for the discriminant?

if it's a negative value, no solutions
if it's a positive value, two solutions
if it's 0, one solution

Which of the following shows the correct value of 50

Orlov [11]

Answer:

None of the options is correct

Step-by-step explanation:

It is important to know that he expression a < x < b means that x is greater than a and less than b. So, for finding the correct value let's analyse each option.

A. 4 < 50 < 5

50 is greater than 4 but it is not less than 5, so, option A is incorrect.

B. 7 < 50 < 8

50 is greater than 7 but it is not less than 8, so, option B is incorrect.

C. 8 < 50 < 9

50 is greater than 8 but it is not less than 9, so, option C is incorrect.

D. 10 < 50 < 11

50 is greater than 10 but it is not less than 11, so, option D is incorrect.

Thus, none of the options is correct.

Brainliest for correct awnser! Hannah thinks of a number. She multiplies the number by 2, adds 4, and then divides the result by

sweet [91]

Answer:

B. Multiply 6 by 3

Step-by-step explanation:

Do the opposite order of what Hannah did. The last step that she did was divide by 3, so you would multiply the result (6) with 3:

B. Multiply 6 by 3

Your step by step for getting the number Hannah started with:

First, multiply 6 with 3:

6 x 3 = 18

Next, subtract 4:

18 - 4 = 14

Next, divide by 2:

14/2 = 7

Hannah started with the number 7.

The range of the function shown on the graph (see attachment) is: D. -9 ≤ y ≤ 8.

<h3>What is a range?</h3>

A range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range refers to the set of all possible output numerical values, which are shown on the y-axis of a graph.

<h3>How to identify the range of this graph?</h3>

The vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

By critically observing the graph shown in the image attached below, we can reasonably infer and logically deduce the following:

Range = [-9, 8]

In interval notation, the range of this graph can be rewritten as -9 ≤ y ≤ 8.
