Answer:

D) x² + 16

A) x − 2

Step-by-step explanation:

(x³ + 3x² + 16x + 48) / (x + 3)

Use grouping:

(x² (x + 3) + 16 (x + 3)) / (x + 3)

Divide:

x² + 16

(x² + x − 6) / (x + 3)

Factor:

(x + 3) (x − 2) / (x + 3)

Divide:

x − 2

PLEASE HELP URGENT :))))

Answer:

P = (3, 3 2/7)

Step-by-step explanation:

The desired point P is the weighted average of the end point values. The weights are the numbers in the ratio of segment lengths. The smallest weight is used for the end point closest to the largest division.

P = (5N +2M)/(5+2) = (5(7, 7) +2(-7, -6))/7 = (35-14, 35-12)/7

. P = (21, 23)/7

P = (3, 3 2/7)

_____

The x-distance from M to N is 7-(-7) = 14 units. The x-distance from P to M must be 5/(5+2) = 5/7 of that, so is (5/7)14 = 10 units. So, the x-coordinate of P is ...

Mx +10 = Px

-7 +10 = 3 . . . . x-coordinate of P

The corresponding y-coordinate can be found from a graph or by a similar calculation.

My +5/7(Ny -My) = Py

Py = -6 +(5/7)(7-(-6)) = -6 +65/7 = -6 +9 2/7 = 3 2/7 . . . . y-coordinate of P

Angle 1 is a complement of angle 2 and measure 2 equals 5 degrees find measure angle 1

ANTONII [103]

Angle one equals 85 because when an angle is a complement of another angle that means their degrees added together equal to 90 degrees. And so you just do 90-5=85 to get your answer.

2×2×2+10-4÷4+3×3×3 can y'all please help this is due tomorrow

baherus [9]

Then you'll need to get started on it pretty soon.
Just take it slow and easy, and remember your order of operations (or PEMDAS).
First look through it and do any multiplications and divisions that you find.
Then do the additions and subtractions.
I just gave it a quick scan and I came up with 26. I dont know if it's correct.
Get to work. You can do this !

Is y= |x|-1 a linear equation

natita [175]

Answer:

y=x-1

Step-by-step explanation:

those lines by the x are absolute value lines and the absolute value of x is x so the equation basically stays the same
