Mathematics

Readme [11.4K]3 years ago
7 0

Answer:

6

Step-by-step explanation:

The rational root theorem states that the roots must be factors of p/q

where p is the constant and q is the coefficient of the highest order term

p = 8  which has factors ±1, ±2,±4,±8

q  = 1 which has factors ±1

The possible roots are ±1, ±2,±4,±8

                                        --------------------

                                           ±1

which simplifies to

±1, ±2,±4,±8

6 is not a possible root

When you translate, (x, y+6) will move
Darya [45]

Answer:

(x, y+6) will vertically move 6 units up.

Step-by-step explanation:

If we move vertically 6 units up, 6 is added to the y-coordinate.

so

(x, y+6) will vertically move 6 units up.

For example, let suppose the point P(-2, 3). When we apply a translation of (x, y+6) to the point P(-2, 3), the coordinates of point P after the translation will be:

(x, y)              →                 (x, y+6)

P(-2, 3)          →                 P(-2, 9)             ∵ P(-2, 3+6)

Therefore, (x, y+6) will vertically move 6 units up.

Answer:

#3=51. #5=85

Step-by-step explanation:

#3. PEMDAS

(2-10×6)-7

PARENTHESIS FIRST

MULTIPLICATION FIRST

10×6=60

60-2=58

58-7=51

#5. PEMDAS

(12-11)+12×7

PARENTHESIS FIRST

12-11=1

1+12×7

MULTIPLICATION FIRST

12×7=84

84+1=85

1. Where will the line y = -1/2 -3 cross the y-axis?
soldier1979 [14.2K]

1) The y- axis is where x = 0, so the line "y = -1/2x - 3" will cross the y-axis when x = 0. You plug in "x = 0" into the equation, and get y = 0 -3, so y = -3. That means the line " y = -1/2x - 3" will cross the y-axis ar (0, -3)

2) If there are 2 parallel lines, then there is no solution, because the definition of parallel lines is, " 2 lines in the same plane, that never meet." That makes the solution inconsistent.
