Is this prime or can it be factored?

poizon [28]

Factor the following:
6 x^2 - 19 x + 10
Factor the quadratic 6 x^2 - 19 x + 10. The coefficient of x^2 is 6 and the constant term is 10.
The product of 6 and 10 is 60. The factors of 60 which sum to -19 are -4 and -15.
So 6 x^2 - 19 x + 10 = 6 x^2 - 15 x - 4 x + 10 = 2 x (3 x - 2) - 5 (3 x - 2):
2 x (3 x - 2) - 5 (3 x - 2)
Factor 3 x - 2 from 2 x (3 x - 2) - 5 (3 x - 2):
Answer: (3 x - 2) (2 x - 5)

Which line has an y-intercept of -2

DiKsa [7]

The y-intercept is found when x is set to 0.

Set x to equal 0 for both equations:

$3(0) - 2y = -6$
$-2y = -6$

Divide both sides by -2:

$y = 3$

The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.

-
$0 + 2y = -2$
$2y = -2$

Divide both sides by 2:

$y = -1$

The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.

Neither line has a y-intercept of -2.

Fining the Unit Rate.

MAVERICK [17]

Answer:

See below ~

Step-by-step explanation:

Option A

Unit Rate = $2.49 / 24
Unit Rate = $1.04 per bottle

Option B

Unit rate = $6.00 / 48
Unit rate = $0.13 per bottle

Option C

Unit rate = $1.86 / 12
Unit rate = $0.16 per bottle

Option C has the lowest rate, hence it is the best deal.

(2a^2b + 3ab^2 - b^3) - (4b^3 - 3ab^2 -6a^2b)

skelet666 [1.2K]

Hi there!

~

$(2a^2b+3ab^2-b^3)-(4b^3-3ab^2-6a^2b)$

Distribute the Negative Sign:

$= 2a^2 b + 3ab^2 - b^3 + -1(4b^3 - 3ab^2 - 6a^2b)\\= 2a^2 b + 3ab^2 + - b^3 + -1 (4b^3) + -1 (-3ab^2) + -1 (-6a^2b)\\= 2a^2 b + 3ab^2 + -b^3 + -4b^3 + 3ab^2 + 6a^2 b$

Combine Like Terms:

$= 2a^2 b + 3ab^2 - b^3 + -4ab^3 + 3ab^2 + 6a^2 b\\= (2a^2 b + 6a^2 b) + ( 3ab^2 + 3ab^2) + (-b^3 + -4b^3) \\= 8a^2 b + 6ab^2 + -5b^3$

Answer : $8a^2 b + 6ab^2 + -5b^3$

Hope this helped you!
