Dan factored x^2+121 into (x+1-11)

1 answer:

4 0

Answer:

Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).

Step-by-step explanation:

The difference of two squares is a special form. a² - b² = (a+b)(a-b).

But, the sum of two squares is prime. a²+ b² cannot be factored.

The function f(x)=3 (x+6)^2+8 is shifted 4 units up and 3 units right to form another function g(x). What is g(x)?

iVinArrow [24]

Answer:

$g(x) = 3\cdot (x+3)^{2}+12$

Step-by-step explanation:

There are two operations involved:

Vertical translation:

$f'(x) = f(x) \pm c,\,c\in \mathbb{R}$ (1)

Note: Positive sign represent a translation upwards.

Horizontal translation:

$f'(x) = f(x\pm c), x\in \mathbb{R}$ (2)

Note: Positive sign represent a translation leftwards.

Then, the new function must be:

$g(x) = f(x-3)+4$

$g(x) = 3\cdot (x+3)^{2}+12$

what is the slop of the like that passes through the points (4,7) and (5,8)? write your answer in simplistic form

Paladinen [302]

Answer:

slope=1

Step-by-step explanation:

Formula for slope is m = y2 - y1 /x2 - x1

you will then use 7-8/4-5

Then -1/-1 which will simplify to 1

X/2 + 3/8 = 1 solve for x

gladu [14]

Answer:

Step-by-step explanation:

hello :

X/2 + 3/8 = 1

X/2 + 3/8 -3/8= 1-3/8

X/2 = 5/3 means : 3x=10 so : x=10/3
