Which of the following is a factor of
X^2
- 2x + 15
Select one
X-5
X+3
None of the above
X-3
Answer:
both (x - 5) and (x - 3) are factors of x^2 - 2x + 15
Step-by-step explanation:
Please write this all on one line: x^2 - 2x + 15.
Recognize that 3*5 = 15. Possible factors of x^2 - 2x + 15 are thus (x - 5) and (x + 3). Multiplying these together results in x^2 - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2 - 2x + 15.
f(x) = x² - 2x + 15
Solution:This function f(x) will have the negative "discriminant" in root ; thus forming complex roots
So this function has no rational roots

Answer:
option (B) 33 is right answer
Answer:
x = 33Step-by-step explanation:
According to Supplementary Angle sum,
104° + x + x + 10° = 180°
=> 2x + 114 = 180
=> 2x = 180 - 114
=> 2x = 66

You take a math quiz that has 25 regular points and 5 bonus points. You get a score of 20, which includes 2 bonus points. Let x represent the score you would have had without the bonus points, Which equation represents this situation?
A. x + 2 = 25 B. x + 20 = 25 C. x + 2 = 20
Answer:
c
Step-by-step explanation:
you score is 20, including bonus points. x=scor without bonus. that means that your normal score plus the bonus equals 20. so x +2=20

Notebooks cost $1.50 each. This weekend they will be on sale for $0.80. What percentage is the sale?
Answer:
33%
Step-by-step explanation:
To start take the original price and divide it by the new sale price. $1.20/$0.80 = 0.66666. We can then round that answer to 0.67. if the new price is 67% of the original price we must then we know that 67% minus the 100% will give us the discount. 100% - 67% = 33%
Answer = 33%

Written as a simplified polynomial in standard form, what is the result when
(3x – 2)2 is subtracted from 9?
Answer:
-9x^2 + 12x + 5
Step-by-step explanation:
I'm assuming you meant (3x – 2)^2. The " ^ " indicates exponentiation and is required. We then have:
9 - (3x – 2)^2, which, when expanded, is
9 - (9x^2 -12x + 4), or:
-9x^2 + 12x + 5

How can you write 200.000 using a whole number and a power
Answer:
2 x 10^5
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.
Question Explanation:
In other words you can write 200,00 using a whole number and a power 10 using scientific notation!
In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.
Solution:
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.

Acellus Find the value of x. Round to the nearest tenth. 33° 6 x = [?] PLEASE HELP DONT PUT RANDOM STUFF GETTING REPORTED
Answer:
3.27
Step-by-step explanation:
Let us assume that the values are the side of a right triangle where;
Hypotenuse = 6 (longest)
Angle of elevation = 33 degrees
Required
x = opposite side
Using the trig identity
Sin theta = opp/hyp
Sin 33 = x/6
x = 6sin33
x = 6(0.5446)
x = 3.27
Hence the value of x is 3.27
Note that the values of the sides are assumed.

Answer:
Step-by-step explanation:
Answer:
x = -3/7
Step-by-step explanation:
5(x + 3) = -2(x - 6)
Multiply the values on the outside of the parenthesis by what is on the inside.
5x + 15 = -2x + 12
Combine like terms by bringing them over to the other side using the necessary operation (addition or subtraction).
Bring -2x over to the left side by adding it to 5x.
5x + 2x = 7x
Bring 15 over to the right side by subtracting it from 12.
12 - 15 = -3
Now we have:
7x = -3
We need to get the x all by itself, so we divide both sides by 7.
7x/7 = x
-3/7 cannot be simplified further, so it is left as -3/7.
