LESSON: SOLVING QUADRATICS EQUATIONS

Mathematics
1 answer:
Misha Larkins [42]3 years ago
8 0

Step-by-step explanation:

x² + 9= 0

(move internode)

x²= -9 (heve no solution and parentheses )

if the number is negative and we are asked to find the root of n (if n is an even number). then it has no solution. example that have solution:

x²= 9

x = √9

x= 3

because, (3)²= (3) × (3)

= 9

or it could be: (-3)²

= 9

You must use parentheses if you want to convert it to the square root

2. x² - 4= -11

(move internode)

x²= -11 + 4

x²= -7 (haven't no solution because 7 is not the number of the square root and there are no brackets)

If I put a different sticker on the 30th, 50th, and 60th pages will any of the first 600 pages have all 3 stickers?
icang [17]

Answer:

so the which page that will have the 3 sticker, we must solve the least common multiple of 30, 50, 60. A common multiple is a number that is a multiple of two or more numbers. The common multiples of 3 and 4 are 0, 12, 24, ....

The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.

so the least common multiple of 30, 50 and 60 is 300. so the page that will have 3 stickers is 300th page

This table shows the results of a survey that asked a group of people what time of day their favorite TV show aired. What time c
irina1246 [14]

Based on the table (see attachment), the time which corresponds to the mode of this data set is: B. 9:00 P.M.

<h3>What is mode?</h3>

A mode simply refers to a statistical term that is used to denote the value that appears most often or occurs repeatedly in a given data set.

This ultimately implies that, a mode represents the value (number) with the highest frequency and this is 9:00 P.M with a frequency of 25.

Mila graphs the point A
melamori03 [73]
Answers:
B. <span>The x-coordinate of point A is 5.
</span>E. <span>Point A is on the x-axis.
</span>
Explanation:
Any point drawn on the coordinates has the general notation of (x,y).
The given point is (5,0). This means that:
The x-coordinate of the point is 5
The y-coordinate of the point is 0

Now, let's check the place of this point.
The x-coordinate of the point is 5. This means that we will move 5 points to the right of the origin on the x-axis
The y-coordinate of the point is 0. This means that we will not move along the y-axis which means that the point stays on the x-axis.

Now, comparing the deduced results with the given choices, we will find that the correct choices are B and E

Hope this helps :)
