What are the roots for 0=3x^2-4x-9
GarryVolchara [31]
3x ^2 - 4x - 9 = 0
3x ^ 2 - 4x = 9
X( 3x - 4) = 9

X = 9

3x - 4 = 9
3x - 4 + 4 = 9 + 4
3x = 13
3x/3 = 13/3
X = 13/3.

The Jackson family rents 6 movies each month. Draw a graph of movies rented versus time. Find the value of the slope and interpr
atroni [7]

Let us say "y" coordinate represents number of movies and "x" coordinate represents number of months.

Movies watched in 1st month = 6

so we can say first ordered pair is (1,6)

Movies watched in 2nd month =6

so we can say second ordered pair is (2,6)

Now we have two points here (1,6) and (2,6)

We can use formula for slope as :

slope = \frac{y2-y1}{x2-x1}

slope = \frac{6-6}{2-1}

slope = 0

The slope of a horizontal line. A horizontal line has slope 0 because all its points have the same y-coordinate. As a result, the formula used for slope evaluates to 0.

The graph is shown here:

The equation of graph would be y=6.

Pythagoream theorem!!! help meeee
seraphim [82]

The equation for Pythagorean theorem is

a^2 + b^2 = c^2

c = the hypotenuse of a right angle, the longest sides

a, and b is the shorter sides of the right angle

Since we have the hypotenuse, and one number for the other side, cut the other side (6) in half because of how a area of a triangle is based off the equation, h x b divided by 2 = A

Plug it into the equation above:

3^2 + b^2 = 8^2

9 + b^2 = 64

b^2 = 55

b = √55

D. x = √55 is your answer
